I need to set the value of leading of text layer in Photoshop. I am first retrieving the selected text layer and then gets its value in a TextItem object. Then I get the value of the leading from a combo-box and set the value of leading using the following code.
var activeTextItem:TextItem = curLayer.textItem;
activeTextItem.leading = ComboBox.text.toString();
This code works fine when using on Windows. But when I try to execute the above code on Mac it always shows the leading as null object.
Can someone please guide me why I am not able to set the value of leading in Mac?
Thanks
I found the solution for this.
The leading has a value called Auto which by default has value a null. Therefore when I use the above code I am not able to set the value as leading parameter is null.
To overcome this I put a check that if leading is null value ie Auto then set the property useAutoLeading to false and once you set the value then again set the useAutoLeading property to true.
if("Auto" == ComboBox.text)
{
activeTextItem.useAutoLeading = false;
activeTextItem.leading = ComboBox.text.valueOf();
activeTextItem.useAutoLeading = true;
}
Thanks.

i have column in database with Int data type, but textbox don't allows null. it gives error "Input string was not in a correct format".
objinsert.VehGrpID = Convert.ToInt32(txtVehGroupID.Text);
Use TryParse instead.
int GrpID = 0;
int.TryParse(txtVehGroupID.Text, out GrpID)
if(GrpID > 0)
objinsert.VehGrpID = GrpID;
You can just special-case out empty values. I am, of course, assuming here that an empty value should map to null.
objinsert.VehGrpID = string.IsNullOrWhiteSpace(txtVehGroupID.Text) ? null : (int?)Convert.ToInt32(txtVehGroupID.Text);
You'll also want to adjust your code to set the textbox's text accordingly.
Your question is also a bit unclear, because you say the textbox won't allow nulls, but you haven't shown us any code that adjusts the textbox text.
You can also use DBNull.Value Field. If a database field has missing data, you can use the DBNull.Value property.
check this link http://msdn.microsoft.com/en-us/library/system.dbnull.value%28v=vs.110%29.aspx
try this
int VehGrpID = Convert.ToInt32(txtVehGroupID.Text);
OR
int VehGrpIDtxtVehGroupID.Text = int.Parse(txtVehGroupID.Text);
The Text property of your textbox is a String type, so you have to perform the conversion in the code.
LATEST UPDATE: Issue answered here. Some one else at stackoverflow had a similar issue and it was resolved. Solution provided for convenience. This is the line of code I was missing:
comboHeaderColumn.useLabelFunctionForFilterCompare = true;
that line is followed by these:
comboHeaderColumn.filterComboBoxBuildFromGrid = true;
comboHeaderColumn.labelFunction = formatState;
where formatState is a local method that formats the data for the combobox.
UPDATE: I've now got the combobox's loading with the correct data, but when I select a value nothing happens. The combo boxes load only data that is in the column, and when you select a value in the combobox, it's supposed to filter the rows on that value. It doesn't.
Thanks for looking. I'm having trouble getting multiple filters to work in Flex in Flash Builder 4 using the ExtendedDataGrid and ComboBox's. Here is an image of part of the grid:
The User Name and City filter properly if you type text into the box's above the column header and the Request Date lets you select date ranges if you click on the Custom bar, but the Request Reason and State ComboBoxes do not list anything. I've created them using comboHeaderColumn.filterComboBoxBuildFromGrid = true; but all it does is put "[object Object]" as the only other selection under All.
I've used this article but it will only allow you to use a single filter for the entire grid.
My finished grid will have about 20 columns and from 20,000 to 450,000 rows of data so the filters are really important and I'll need more than one.
The code is very straight forward and loops through all the returned data and if the column is identified as a filter column it does this:
comboHeaderColumn.filterComboBoxDataProvider = codeValuePairs;
comboHeaderColumn.filterComboBoxLabelField = "Value";
comboHeaderColumn.filterControl = "ComboBox";
comboHeaderColumn.filterOperation = FilterExpression.FILTER_OPERATION_TYPE_EQUALS;
comboHeaderColumn.headerText = ac.Header;
comboHeaderColumn.dataField = ac.Name;
if( ac.Header == "State" || ac.Header == "Request Reason" )
{
comboHeaderColumn.filterComboBoxBuildFromGrid = true;
}
ProfileDataColumns.push(comboHeaderColumn);
This creates 2 entries in the combo box: All and [object Object]
What am I missing??? Anyway, after half a day searching I decided to reach out.
Any suggestions or direction to an article would be very much appreciated.
Thanks.
I have a drop down list that I am binding to a record that clearly sets value=0, text=''
the dropdownlist looks fine, i do not see any text in the control BUT when i try to validate in the code behind it says the dropdownlist.text = 0
i do not know why the control shows no text on the form but holds a value in its .text property, it doesn't make any sense. can anyone help? Thanks.
I fixed the issue I was having by inserting a null value along with the text of '' and now the dropdownlist.text is = '' intead of 0.
I encounter this problem repeatedly, and haven't a clue what is causing it. I get an exception in the DataBind: SelectedValue which is invalid because it does not exist in the list of items.
Here are some important pieces of information:
I reload listOrgs periodically when the underlying data has changed.
The Organization.DTListAll call returns 2 Int, String pairs.
There are no duplicate or null values in the returned data
After the first two lines below, listOrgs.Items.Count is 0, and the Selected Value is 0
The selected value after the DataBind operation executes is the ID value from the first row in the data
This exception happens the very first time this code is executed after a fresh page load
listOrgs.Items.Clear();
listOrgs.SelectedValue = "0";
listOrgs.DataSource = new Organization().DTListAll(SiteID);
listOrgs.DataTextField = "OrganizationName";
listOrgs.DataValueField = "OrganizationID";
listOrgs.DataBind();
Apparently the solution I posted wasn't entirely effective... Eventually in my application I changed to this:
listOrgs.Items.Clear();
listOrgs.SelectedIndex = -1;
listOrgs.SelectedValue = null;
listOrgs.ClearSelection(); // Clears the selection to avoid the exception (only one of these should be enough but in my application I needed all..)
listOrgs.DataSource = new Organization().DTListAll(SiteID);
listOrgs.DataTextField = "OrganizationName";
listOrgs.DataValueField = "OrganizationID";
listOrgs.DataBind();
I kept getting this error.
Weird thing is that before I set the datasource and rebind after deleting an item the selected index = -1.
If I explicitly set the selectedIndex = -1; then it works and doesn't throw an error.
So even though it was already -1 setting it to -1 stops it from erroring.
Weird eh?
Try setting listOrgs.SelectedValue = "0" after you refresh the DataSource
At the moment you are trying to select the first item in an empty list.
Change the first two line with this :
listOrgs.SelectedItem.Selected = false;
listOrgs.Items.Clear();
In case you still have this problem this is how i resolved it:
listOrgs.SelectedIndex = -1; // Clears the SelectedIndex to avoid the exception
listOrgs.DataSource = new Organization().DTListAll(SiteID);
listOrgs.DataTextField = "OrganizationName";
listOrgs.DataValueField = "OrganizationID";
listOrgs.DataBind(); //Unless you have "listOrgs.AppendDataBoundItems = true" you don't need to clear the list
#PMarques answer helped me out and did solve my problem.
However whilst experimenting, it clicked in my head why I was gettign the error in the first place.
I was setting the "Text" attribute thinking that it might create an encompassing label or fieldset + legend, for me (which it doesn't).
The Text property for a list is infact the SelectedValue property for a ListControl.
So my mistake in misinterpreting what the text property did.
Not sure it is your case, but I had the same problem and apparently there was no explanation, then I realized doing a copy and paste on notepad of a field of database that at the beginning of the value there was a NULL.
Curious thing was that a select joining tables was working. I deleted the row and reinserted, after was working fine.
I was getting the same error repeatedly and try ending up by not setting the default selected value to Index -1.
I commented my code ddlDRIBidAmt.SelectedValue = -1
This value was set at the time where my Page Controls were reset to default values.
I know its too late to answer, but what I tried is an dirty solution but it worked.
After databinding, I am insert a item at index 0
ddl.Items.Insert(0, new ListItem("---Select---","-1"));
And on setting,
I am placing try catch, In catch i am setting Value to -1
I am trying to access an XMLList item and convert it to am XML object.
I am using this expression:
masonicXML.item.(#style_number == styleNum)
For example if there is a match everything works fine but if there is not a match then I get an error when I try cast it as XML saying that it has to be well formed. So I need to make sure that the expression gets a match before I cast it as XML. I tried setting it to an XMLList variable and checking if it as a text() propertie like this:
var defaultItem:XMLList = DataModel.instance.masonicXML.item.(#style_number == styleNum);
if(defaultItem.text())
{
DataModel.instance.selectedItem = XML(defaultItem);
}
But it still give me an error if theres no match. It works fine if there is a match.
THANKS!
In my experience, the simplest way to check for results is to grab the 0th element of the list and see if it's null.
Here is your code sample with a few tweaks. Notice that I've changed the type of defaultItem from XMLList to XML, and I'm assigning it to the 0th element of the list.
var defaultItem:XML =
DataModel.instance.masonicXML.item.(#style_number == styleNum)[0];
if( defaultItem != null )
{
DataModel.instance.selectedItem = defaultItem;
}
OK I got it to work with this:
if(String(defaultItem.#style_number).length)
Matt's null check is a good solution. (Unless there is the possibility of having null items within an XMLList.. probably not, but I haven't verified this.)
You can also check for the length of the XMLList without casting it to a String:
if (defaultItem.#style_number.length() > 0)
The difference to String and Array is that with an XMLList, length() is a method instead of a property.
