In a customised form I would have a create Purchase Menubutton which opens a dialog to create a purchase order.
But I need to select few records like one or two lines and then create purchase order only for those records. How do I do that?
Take a look on the "Create purchase order" button on the SalesTable form.
It works differently: you select the lines to purchase after you press the button, but it might work in your case also.
Also have a look on how to use multiple selected records in a grid.
Here is a piece of code which allows you to get the record from the previous form.
You have to put this piece of code in the INIT method of the dialog. So you have to override the init of the dialog.
DmoVehicleTable vehicleTable;
DmoVehicleId vehId;
// Get the vehicle ID from the previous form
if (element.args() && element.args().record())
{
switch (element.args().record().TableId)
{
case (tableNum(DmoVehicleTable)):
vehicleTable = element.args().record();
vehId = vehicleTable.VehicleId;
break;
default:
throw error (strFmt("#SYS477", this.name()));
}
}
I hope this will help you.

Hypothetical:
Say i'm having someone order a cake and they choose vanilla or chocolate, and then they have to choose a frosting
if vanilla: strawberry or buttercream
if chocolate: mocha, dark chocolate or buttercream.
Right now the frosting value in the data model can accept all four options, so all four show up in the dropdown.
a) is there a way to change the binding for the second dropdown after the first is chosen?
This can be done without having the data saved in any datasource. Simply do the following...
Suppose the first dropdown is named primaryDropdown and the second dropdown is called secondaryDropdown. In the primaryDropdown options set the following:
["Vanilla", "Chocolate"]
Also, make sure to uncheck the option allowNull and on the onAttach event handler, place the following:
widget.value = "Vanilla";
Now we move on to the secondaryDropdown. Here, we will do a binding so place the following in the options value:
getAvailableOpts(#widget.root.descendants.primaryDropdown.value)
In the client script, we need to make sure that function exists so please paste the following in any client script:
function getAvailableOpts(primaryValue){
var options;
switch(primaryValue){
case "Vanilla":
options =["Strawberry","Buttercream"];
break;
case "Chocolate":
options = ["Mocha","Dark Chocolate","Buttercream"];
break;
default:
options = [];
}
return options;
}
From here, you are good; However we can still make it better. For that, make sure to also uncheck the allowNull option for the secondaryDropdown and then we need to add some logic in the onValueChange event handler of the primaryDropdown.
widget.root.descendants.secondaryDropdown.value = widget.root.descendants.secondaryDropdown.options[0];

Im guessing you set the dropdown "possible value" options in the data source and you have those fields as just string fields in your table.
the quick and dirty way to do this is go to the Cake drop down and on the Property Editor>Events>OnValueChange select Custom Action and use this Code
if(widget.value==="Vanilla"){
widget.root.descendants.Field.options = ['Strawberry','Buttercream'];
}else if (widget.value === "Chocolate"){
widget.root.descendants.Field.options = ['Mocha','Dark Chocolate','Buttercream'];
}
"Field" here is replaced with the name of the dropdown box for your frostings
also go to the property editor of the frostings dropdown and delete everything in the options field there.
I was trying to solve for a similar situation and created an additional table to serve as a lookup.
I have a drop down for CATEGORY with possible options set on the field in the main data source.
Then I have a second table with 2 Columns: CATEGORY, and SUB_CATEGORY.
On the entry form I have options for the SUB_CATEGORY drop down set to SUB_CATEGORY on the CATEGORY_MATRIX lookup table.
Then for an onValueEdit event on the CATEOGRY drop down I have a script to reload the CATEGORY_MATRIX table source based on the value of the CATEGORY drop down in the query so when the CATEGORY is selected only valid SUB_CATEGORY options are shown in the second drop down.
var datasource = app.datasources.CATEGORY_MATRIX
datasource.query.filters.CATEGORY._equals = newValue;
datasource.load();
There may be more efficient ways to do this but the benefit is I could create another form page and dynamically add new combos so there isn't any required code change as new combos are needed.
I am new in ASP.net MVC.
The website I am modifying has a drop-down list called "site", and users can change the site, then the rows of sales of the site would be shown accordingly.
Now my client wants the "site" drop-down list to include "All Sites", so when "All Sites" is selected, all sales across all sites would be shown.
Can someone give me a direction about what I should do?
Should I change table mapping to let every sale always point to an actual site and dummy site called "All Sites"?
Thanks

You can make a function with an optional parameter which will help us to decide whether we have to show sales of all sites or sales of only selected site.
The function will looks something like this:
public IEnumerable<Sale> GetSales(int? id)
{
if (id != null)
{
var salesBySite = getSalesBySite((int)id);
return salesBySite;
}
else
{
var salesOfAllSites = getAllSales();
return salesOfAllSites ;
}
}
In drop-down list all options should have values as the ids of respective site but the option "AllSites" should not have value or empty value.
When user select any site from dropdown, id will be passed to the function GetSales. If user select AllSites from dropdown then no id will be passed to function, function will return the sales of all sites.
In my opinion, there is no right way to do that. But it looks like a "report" to me. User is actually selecting a filter.
You shouldn't change the table, you can summarize on C# or create a view
I created a form with a single data source: InventJournalTable.
I also added a grid on it and two field from the data source : JournalType and JournalId
The ActionPane has a button and in its clicked event handler I am trying to do the following:
1. add a new data source and join it with the current one on JournalId
2. add to fields from the newly added data source to the current Grid.
This is what I have until now ... just for testing.. I have tried to access data source and add a range. It works nice, maybe the join is working too, but how can I add those two fields?
void clicked()
{
Query query;
QueryBuildDataSource qbdsInventJournalTable;
QueryBuildDataSource qbdsvwInventJournals;
super();
query = InventJournalTable_ds.query();
qbdsInventJournalTable = query.dataSourceTable(tableNum(InventJournalTable));
qbdsInventJournalTable.addRange(fieldNum(InventJournalTable, JournalType)).value(queryValue(InventJournalType::LossProfit));
qbdsvwInventJournals = qbdsInventJournalTable.addDataSource(tableNum(vwInventAdjJrnlCostAmount));
qbdsvwInventJournals.addLink(fieldNum(InventJournalTable, JournalId), fieldNum(vwInventAdjJrnlCostAmount, JournalId));
qbdsvwInventJournals.joinMode(JoinMode::OuterJoin);
//gridOverview.addDataField(
InventJournalTable_ds.executeQuery();
}
One more thing, I plan to add another button named "Remove details" which will remove the second data source and the grid should return to its initial state.
Am I on the right track at least? Can I get some hints about this?
Instead of dynamically adding the datasource/fields/etc have you considered just adding them on the form, but disabling the joined datasource until you need it? Seems to me like a simpler/cleaner solution.

I create a menu dynamically. I add several checkable actions into one menu. Sometimes actions may have the same text that user sees. It's up to user (actually user adds commands into menu).
The problem is in this case clicking works wrong. If I click on the first action (from 2 with the same texts) everything is good but if I click on the second one, both actions are selected. I don't understand why. The code where actions have been created is here:
for (int i = 0; i< currentList.size(); i++)
{
QString lanKey = currentList.at(i)->Language->toString();
QAction* lanAction = new QAction(this);
QString name ="action_" + currentList.at(i)->Id->toString();
lanAction->setObjectName(name);
lanAction->setText(lanKey);
lanAction->setCheckable(true);
lanAction->setData(i);
connect(lanAction, SIGNAL(triggered(bool)), this, SLOT(ShowSomething(bool)));
ui->menuMy->addAction(lanAction);
}
Here, lanKey is language that may be the same for different actions. Anyway click on the specific action should lead only to checking of this action. What's wrong?
The slot is here:
void VMainWindow::ShowSomething(bool IsTriggered)
{
QAction* senderAction = (QAction*)sender();
int listIndex = senderAction->data().toInt();
if (IsTriggered)
{
CreateEditor(subtitles, listIndex);
}
else
{
//hide this editor
QString name = "editor" + editorsList->Id->toString();
QDockWidget* editorDock = this->findChild<QDockWidget*>(name);
if (editorDock != 0)
{
this->removeDockWidget(editorDock);
this->setLayout(layout());
}
}
}
Thanks
The source of problem is found: it turned out that the slot finds the checked action wrong - by text, not by id.
I can't find a logical issue in the code you posted so far. Here are a couple of options which I would try in order to resolve this problem:
Limit the users possibilities when adding items to a menu so that he can't add two items with the same name.
Add qDebug() output to ShowSomething to see if there is a problem with signals&slots. For example, if the slot gets called once for the first item but twice for the second item there is a problem there.
Debug into CreateEditor step-by-step.
As the problem seems to appear only for actions with a similar name, you should make sure that you never make a lookup of an action (or something related) by its text() but rather by its data() or objectName() (assuming that currentList.at(i)->Id will always be unique)
I have a dropdown list (FK) which I would like to set and display a default value based on a login userid. Can you please tell me how to do it? I only want to affect the dropdown filter that appear at the top above the Gridview.
Thanks

If you only want this functionality in the DropDown list that appears in the Filter Criteria section, just modify the URL by adding the QueryString parameters you would like to filter by. The DynamicFilter will pick up the values from the QueryString and set the DropDown lists accordingly. (fyi. this is the same functionality that the ForeignKey.ascx FieldTemplate provides)
It would be nice if there was a better way to actually create this URL (instead of using string), but as of right now, any solution I provide is probably going to break in a subsequent version.
example (in page_load)
Response.Redirect("~/Employees/List.aspx?ReportsTo=1234");
Is this a universal change, or just for one foreign key relationship?
Assuming it is for just one foreign key relationship, you could create a new FieldTemplate, to be used just for that relationship. The New FieldTemplate would be a copy of the default "ForeignKey" FieldTemplate. In the New FieldTemplate modify the OnDataBinding (or Page_PreRender) event to set the "default value" of the DropDownList.
Then, to force the New FieldTemplate to be used for that relationship, you would need to use the System.ComponentModel.DataAnnotations.UIHint attribute on the member of your Entity Class that represents that foreign key relationship. (links below)
http://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.uihintattribute.uihint.aspx
or http://www.asp.net/learn/3.5-SP1/video-291.aspx (around 07:30 mins)
For a little help, you could take a look at the DynamicData Futures release on CodePlex. Specifically the "Populate Insert templates with values from filters" section. http://www.codeplex.com/aspnet/Release/ProjectReleases.aspx?ReleaseId=14475
I have figured out a workaround, but am open to a more elegant solution.
I edited the FilterUserControl.ascx.cs by inserting the following line in the Page_Init after PopulateListControl(DropDownList1);
DropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(DropDownList1.Items.FindByText("Bob")); // Username is hardcoded just for test
This seems to work but I would prefer using the custom Partial Entity Class with metadata to solve this if possible.
I have solved this in an application I am working on, in your insert view template code behind:
In ItemCreated event for the details view:
foreach (DetailsViewRow row in DetailsView1.Rows)
{
foreach (Control ctl in row.Controls)
foreach (Control c in ctl.Controls)
foreach (Control x in c.Controls)
{
if (x.ClientID.Contains("tblName"))
{
foreach (Control y in x.Controls)
{
if (y.ClientID.Contains("DropDownList"))
{
ddl = y as DropDownList;
ddl.SelectedValue = Convert.ToString(UserId);
ddl.Enabled = false;
}
}
}
}
}
With this code, when a user is logged in and they go to insert some entity (tblName) the drop down list (fk to userId) is already selected and disabled.
