We have a table with a large amount of data and I do not want to load it at once for my dxDataGrid.
I want to implement paging with Skip / Take which is supplied from the dxDataGrid's DataSourceLoadOptions.
This is my controller:
[HttpGet]
public async Task<Object> GetSalesOrdersWithTotals(DataSourceLoadOptions loadOptions)
{
try
{
var results = await SalesOrderService.GetSalesOrdersWithTotals(loadOptions.Skip, loadOptions.Take, 40);
loadOptions.Skip = 0;
loadOptions.Take = 0;
return DataSourceLoader.Load(results, loadOptions);
}
catch (Exception ex)
{
return Json(new { code = "422", success = false, message = "Unable to fetch sales orders with totals - " + ex.ToString() });
}
}
This is the service that returns the data:
public async Task<IEnumerable<SalesOrderWithTotals>> GetSalesOrdersWithTotals(int skip, int take, int defaultPageSize)
{
if (take == 0)
{
//Fix for passing a 0 take
take = defaultPageSize;
}
var salesOrderWithTotals =
from o in _context.SalesOrder
select new SalesOrderWithTotals
{
SalesOrderId = o.SalesOrderId,
Net = _context.SalesOrderItem.Where(it => it.SalesOrderId == o.SalesOrderId).Select(it => it.Qty == null ? 0 : it.Qty.Value * it.UnitPrice == null ? 0 : it.UnitPrice.Value).Sum(),
Tax = _context.SalesOrderItem.Where(it => it.SalesOrderId == o.SalesOrderId).Select(it => it.Qty == null ? 0 : it.Qty.Value * it.UnitPrice == null ? 0 : it.UnitPrice.Value).Sum() * (o.Tax.Percentage /100),
Gross = _context.SalesOrderItem.Where(it => it.SalesOrderId == o.SalesOrderId).Select(it => it.Qty == null ? 0 : it.Qty.Value * it.UnitPrice == null ? 0 : it.UnitPrice.Value).Sum() + _context.SalesOrderItem.Where(it => it.SalesOrderId == o.SalesOrderId).Select(it => it.Qty == null ? 0 : it.Qty.Value * it.UnitPrice == null ? 0 : it.UnitPrice.Value).Sum() * (o.Tax.Percentage / 100),
Name = o.Customer.Name,
CustomerOrderNumber = o.CustomerOrderNumber,
Contact = o.Contact,
OrderDate = o.OrderDate
};
return await salesOrderWithTotals.Skip(skip).Take(take).ToListAsync();
}
Looking at SQL profiler, this takes the first 40 records but of course the dxDataGrid is not aware of the total count of records so pagination is not available.
What would be the best method to achieve what I want in this case?
Many thanks
You must do an extra query to get the count of your SalesOrder and keep it in for example salesOrderCount. Then keep the Load method return data as bellow.
LoadResult result = DataSourceLoader.Load(results, loadOptions);
LoadResult has a parameter called totalCount so set it with the real count of your data:
result.totalCount = salesOrderCount;
and then
return result;
Now the dxDataGrid is aware of the total count of records.
This is my datatables serverside implementation. FilterInput contains 5 variables:
Level <- string
Message <- string
Exception <-string
StartDate <- DateTime
EndDate <- DateTime
For some reason when I run this code as it is, I will always get this error:
{System.NullReferenceException: Object reference not set to an
instance of an object.
This is referring to this line:
data = data.Where(
u => u.Level.ToString().ToLower().Contains(FilterInput.Level.ToLower()) &&
u.Message.ToString().ToLower().Contains(FilterInput.Message.ToLower()) &&
u.Exception.ToString().ToLower().Contains(FilterInput.Exception.ToLower())
).ToList();
However, if I remove the search for FilterInput.Exception, everything runs fine again. I have tested it with input ("abc") or without input ("") and the results are the same. The other FilterInputs don't have the same error.
public JsonResult Search(SearchViewModels Input, EventLogsSearchViewModel FilterInput)
{
JsonResult result = new JsonResult(null);
try
{
var data = dbContext.EventLogs.ToList();
int totalRecords = data.Count;
var modelStructure = new Dictionary<int, string>();
modelStructure.Add(1, "Level");
modelStructure.Add(2, "TimeStamp");
modelStructure.Add(3, "LogEvent");
modelStructure.Add(4, "Message");
modelStructure.Add(5, "MessageTemplate");
modelStructure.Add(6, "Exception");
modelStructure.Add(7, "Properties");
var StartDate = FilterInput.StartDate != default(DateTime);
var EndDate = FilterInput.EndDate != default(DateTime);
if ((!string.IsNullOrEmpty(FilterInput.Level) && !string.IsNullOrWhiteSpace(FilterInput.Level)) ||
(!string.IsNullOrEmpty(FilterInput.Message) && !string.IsNullOrWhiteSpace(FilterInput.Message)) ||
(!string.IsNullOrEmpty(FilterInput.Exception) && !string.IsNullOrWhiteSpace(FilterInput.Exception)) ||
(StartDate && EndDate))
{
data = data.Where(
u => u.Level.ToString().ToLower().Contains(FilterInput.Level.ToLower()) &&
u.Message.ToString().ToLower().Contains(FilterInput.Message.ToLower()) &&
u.Exception.ToString().ToLower().Contains(FilterInput.Exception.ToLower())
).ToList();
data = data.Where(u => u.TimeStamp >= FilterInput.StartDate && u.TimeStamp <= FilterInput.EndDate).ToList();
}
if (!(string.IsNullOrEmpty(Input.Order) && string.IsNullOrEmpty(Input.OrderDir)))
{
var columnName = modelStructure.FirstOrDefault(f => f.Key == Convert.ToInt32(Input.Order));
data = data.AsQueryable().OrderBy(columnName.Value + " " + Input.OrderDir).ToList();
}
int recFilter = data.Count;
data = data.Skip(Input.StartRec).Take(Input.PageSize).ToList();
var modifiedData = data.Select(u => new EventLogsListViewModel
{
Id = u.Id,
Message = u.Message,
MessageTemplate = u.MessageTemplate,
Level = u.Level,
TimeStamp = u.TimeStamp,
Exception = u.Exception,
Properties = u.Properties,
LogEvent = u.LogEvent
});
result = this.Json(new
{
draw = Convert.ToInt32(Input.Draw),
recordsTotal = totalRecords,
recordsFiltered = recFilter,
data = modifiedData,
order = Input.Order,
orderdir = Input.OrderDir
});
}
catch (Exception e)
{
logger.LogError(e, LoggingGlobals.LoadingException);
}
return result;
}
EDIT: The exception still happens even when FilterInput.Exception is not null
I am trying to use a DocumentListener on a number of JTextFields. I need to know which textField is coming into the DocumentEvent so I can do some specific processes. Below is how I have my DocumentListener coded and one of the JTextFields set up [thanks to this example: How to get JTextField name in which is Document placed? ](my textField is declared at a higher scope).
How do I fix this?
final DocumentListener documentListener = new DocumentListener() {
#Override
public void changedUpdate(DocumentEvent documentEvent) {
printIt(documentEvent);
}
#Override
public void insertUpdate(DocumentEvent documentEvent) {
printIt(documentEvent);
}
#Override
public void removeUpdate(DocumentEvent documentEvent) {
printIt(documentEvent);
}
private void printIt(DocumentEvent documentEvent) {
final DocumentEvent.EventType type = documentEvent.getType();
String typeString = null;
final JTextField textField = (JTextField) documentEvent.getDocument().getProperty("parent");
if (type.equals(DocumentEvent.EventType.CHANGE)) {
typeString = "(parent: " + textField + ") Change";
} else if (type.equals(DocumentEvent.EventType.INSERT)) {
typeString = "(parent: " + textField + ") Insert";
} else if (type.equals(DocumentEvent.EventType.REMOVE)) {
typeString = "(parent: " + textField + ") Remove";
}
System.out.print("Type : " + typeString);
final Document source = documentEvent.getDocument();
final int length = source.getLength();
System.out.println("Length: " + length);
}
};
My JTextField is coded like the following...
textFieldFencing_LC1 = new JTextField();
textFieldFencing_LC1.setHorizontalAlignment(SwingConstants.CENTER);
textFieldFencing_LC1.setFont(new Font("Tahoma", Font.PLAIN, 9));
textFieldFencing_LC1.setColumns(10);
textFieldFencing_LC1.setBounds(234, 535, 85, 14);
panelLC.add(textFieldFencing_LC1);
textFieldFencing_LC1.getDocument().addDocumentListener(documentListener);
textFieldFencing_LC1.getDocument().putProperty("parent",textFieldFencing_LC1);
The output I want should look like this
Type : (parent: textFieldFencing_LC1) InsertLength: 1
Type : (parent: textFieldFencing_LC1) InsertLength: 1
The output I am getting looks like this ...
Type : (parent: javax.swing.JTextField[,234,535,85x14,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource#384cdfdd,flags=296,maximumSize=,minimumSize=,preferredSize=,caretColor=sun.swing.PrintColorUIResource[r=51,g=51,b=51],disabledTextColor=javax.swing.plaf.ColorUIResource[r=184,g=207,b=229],editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],selectedTextColor=sun.swing.PrintColorUIResource[r=51,g=51,b=51],selectionColor=javax.swing.plaf.ColorUIResource[r=184,g=207,b=229],columns=10,columnWidth=0,command=,horizontalAlignment=CENTER]) InsertLength: 2
Type : (parent: javax.swing.JTextField[,234,535,85x14,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource#384cdfdd,flags=296,maximumSize=,minimumSize=,preferredSize=,caretColor=sun.swing.PrintColorUIResource[r=51,g=51,b=51],disabledTextColor=javax.swing.plaf.ColorUIResource[r=184,g=207,b=229],editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],selectedTextColor=sun.swing.PrintColorUIResource[r=51,g=51,b=51],selectionColor=javax.swing.plaf.ColorUIResource[r=184,g=207,b=229],columns=10,columnWidth=0,command=,horizontalAlignment=CENTER]) InsertLength: 3
After reading the documentation on this Class, I realized the putProperty(Object,Object) method would allow me to put a String into it. So, now my listener on my JTextField looks like this...
textFieldFencing_LC1.getDocument().addDocumentListener(documentListener);
textFieldFencing_LC1.getDocument().putProperty("parent","LC1"); // String, String
Note, the second parameter in the putProperty() is a String with meaning for me, so I can check for LC#. While the update in the DocumentListener looks like this...
final DocumentEvent.EventType type = documentEvent.getType();
String typeString = null;
// Cast documentEvent to String
txtField.setText( (String) documentEvent.getDocument().getProperty("parent") );
if (type.equals(DocumentEvent.EventType.CHANGE)) {
typeString = "(parent: " + txtField.getText() + ") Change";
} else if (type.equals(DocumentEvent.EventType.INSERT)) {
typeString = "(parent: " + txtField.getText() + ") Insert";
} else if (type.equals(DocumentEvent.EventType.REMOVE)) {
typeString = "(parent: " + txtField.getText() + ") Remove";
}
System.out.print("Type : " + typeString);
final Document source = documentEvent.getDocument();
final int length = source.getLength();
System.out.println("Length: " + length);
}
Output now looks like...
Type : (parent: LC1) RemoveLength: 0
Type : (parent: LC1) InsertLength: 1
Type : (parent: LC1) InsertLength: 2
Type : (parent: LC1) InsertLength: 3
Bottom line: a referenced Class and two lines of code placed on the JTextFields I need to listen to so an automatic update occurs, is a lot better than adding a CaretListener on all of those fields.
I have a function like this
public bool CheckMentorAccess()
{
bool blnAllow = false;
try
{
string strSelectMentorQuery = "SELECT COUNT(DISTINCT MLL.LED_ID) FROM M_USER_DETAILS MUD INNER JOIN M_LEADERLED MLL " + "ON MLL.LED_ID = MUD.PK_ID WHERE MLL.LEADER_ID = '" + Session["UserID"].ToString() + "' AND MUD.ACTIVE = 1 AND MLL.START_DATE <= Getdate() AND" + " MLL.END_DATE > Getdate()";
int intNoOfMembers = Convert.ToInt32(cSQLHelper.myExecuteScalar(strSelectMentorQuery));
if (intNoOfMembers > 0)
{
blnAllow = true;
}
}
catch (Exception ex)
{
ExceptionLogger.LogException(ex);
blnAllow = false;
}
// Return the value
return blnAllow;
}
And then I use if like this
if ((Int32.Parse(Session["ROLE_ID"].ToString()) == 3) && (CheckMentorAccess() == true))
{
cmbempList.Visible = true;
}
but it is throwing a null reference exception on the first line of the sample above
Can anyone help me out..
You can try
if (Session["ROLE_ID"] != null && (Int32.Parse(Session["ROLE_ID"].ToString()) == 3) && (CheckMentorAccess() == true))
{
cmbempList.Visible = true;
}
First check that Session["ROLE_ID"] exists before you use ToString.
It is always safer to use Convert.ToString.
Well, if the stack trace only points at that line, I'd guess this is the problem:
Int32.Parse(Session["ROLE_ID"].ToString())
That will throw a NullReferenceException if Session["ROLE_ID"] returns null.
(It will throw FormatException if the value exists in the session but isn't a valid integer.)
It's possible that it's the call to CheckMentor() which is failing, of course - but then your stack trace should say so. That could fail if cSQLHelper is null, for example.
Try this - check the values you are using when you call the method:
if (Session["ROLE_ID"] != null)
{
if ((Int32.Parse(Session["ROLE_ID"]) == 3) && (CheckMentorAccess()))
{
cmbempList.Visible = true;
}
}
and check in the method
public bool CheckMentorAccess()
{
if (Session["UserID"] == null)
{
throw new NullReferenceException("UserID is null");
}
bool blnAllow = false;
try
{
string strSelectMentorQuery = "SELECT COUNT(DISTINCT MLL.LED_ID) FROM M_USER_DETAILS MUD INNER JOIN M_LEADERLED MLL " + "ON MLL.LED_ID = MUD.PK_ID WHERE MLL.LEADER_ID = '" + Session["UserID"].ToString() + "' AND MUD.ACTIVE = 1 AND MLL.START_DATE <= Getdate() AND" + " MLL.END_DATE > Getdate()";
int intNoOfMembers = Convert.ToInt32(cSQLHelper.myExecuteScalar(strSelectMentorQuery));
blnAllow = intNoOfMembers > 0;
}
catch (Exception ex)
{
ExceptionLogger.LogException(ex);
blnAllow = false;
}
// Return the value
return blnAllow;
}
I have a gui class, The functions optional value getting error. If i am not passing the fillcolor and other optional values.
Error:
ReferenceError: Error #1069: Property fillColor not found on String and there is no default value.
AS 3.0
var windowBase:Sprite = UIClip("Sprite");
/* sliderClip = Gui.UIClip("MovieClip",{width:100, height:50, fillColor:0xFFFF0D, alpha:.7});
*/
function UIClip (type:String, params:object = '') {
var clip;
trace("Hello")
if (type == 'MovieClip') {
clip = new MovieClip ;
} else {
clip = new Sprite;
}
//trace(params + "params.fillColor " + params.fillColor)
if (params is Object) {
clip.graphics.beginFill ((params.fillColor != "") ? params.fillColor : 0xFFFFFF, params.alpha ? params.alpha : 1 );
clip.graphics.lineStyle (params.lineThickness != "" ? params.lineThickness : 1, params.borderColor ? params.borderColor: 0x000000);
clip.graphics.drawRoundRect (0,0,
(params.width != undefined ) ? params.width : 100,
(params.height != undefined) ? params.height : 100 ,
params.eW ? params.eW : 0,
params.eH ? params.eH : 0);
clip.graphics.endFill ();
//trace("Hello")
}
return clip;
}
How can I solve this?
Condition "if (params is Object)" is true. String is object, too.
I'm using null for optional params if they have no default value.
Try this:
function UIClip (type:String, params:object = null)
and test "if (params != null)"
