I have a RadGrid setup so that double clicking a row opens a form under the row to allow editing. The form itself lives in a web user control.
On this form one of the fields is a CheckBox. It looks like this.
The code in the 'Checked=' bit sees that on edit the Checked property gets set to True or False. Perfect.
However, when I hit the Add New Record button, this line gets a problem.
Exception Details: System.InvalidCastException: Specified cast is not valid.
Source Error:
Source File: c:\Dev\RadGrid\RadGrid\Controls\ContactDetails.ascx Line: 26
It's pretty easy to understand why. DataItem.con_Is_Active has no value on an Add New Record insert.
My question is, were do I intercept this to prevent this error on Adding a new Record?
I've looked for but have been unable to find the InitInsertButtons click event if any such event exists..
I'm sure this is simple I just don't know where to put such a check. I suppose what I'd like to do is set the DataItem.con_Is_Active property some default value (like 'False') before the it gets to this point.

The splitter is similar to the webmail demo (fulscreen)
However when the page loads you can clearly see the splitter be small, then "POP" into fullscreen.
Is there any way around that?? at least somehow set a default height so the popping isn't so in your face.

Thank you

I tried following to export to pdf in Landscape page orientation:
RadGridResult.ExportSettings.Pdf.PageHeight = Unit.Parse("215mm")
RadGridResult.ExportSettings.Pdf.PageWidth = Unit.Parse("260mm");
But it didn't work, and I have no idea on how to export to Word in Landscape orientation.
But I can do it with Excel just fine. Is there anyway to "convert" Excel to PDF or Word format on the fly?
THanks
LamK.

By default, when we export from RadGrid to MS Word, it automatically has 1 inches page margin, I would like to programmatically change it to 0.5.
Would you please show me how to do that?
Thanks

I have a Radgrid on an ASP.NET form and it is bound to a database table. In the view mode one of the columns has a text value in it that shows a mode. I am using an edit form. In the edit form I have a dropdown on that same field that allows the user to select one of three choices. I can find the dropdown in the edit template using
But what I can't figure how to get is the current data value in the current data row. I know it is in the griddataitem but how do I get to this in the itemdatabound event. I want to "jam" the dropdown list to what is currently in the grid before it goes to edit mode on that row.
Thanks in advance for your help.

i have a rad Filter like below. i want to switch out the Display Name based on a condition.
<
telerik:RadFilter ID="WorkOrdersRadFilter" runat="server" Skin="WebBlue" ShowApplyButton="true"
OnApplyExpressions="WorkOrdersRadFilter_Apply" ApplyButtonText="Filter Work Orders"
OnPreRender="RadFilter_PreRender" OnFieldEditorCreating="RadFilter_FieldEditorCreating"
OnFieldEditorCreated
="RadFilter_FieldEditorCreated"
>
<FieldEditors>
<telerik:RadFilterTextFieldEditor FieldName="WORKORDERNUMBER" DisplayName="Work Order#"
DataType="System.String" />
<
goldcustom:RadFilterComboBoxEditor FieldName="WOTYPENAME" DisplayName="WO Type"
DataTextField="WOTYPENAME" DataSourceID="WorkOrderTypeFilterODS" DataType="System.String"
ComboBoxSkin="WebBlue" />
<
telerik:RadFilterTextFieldEditor FieldName="TRACKINGNUMBER" DisplayName="Tracking#"
DataType="System.String" />
<telerik:RadFilterTextFieldEditor FieldName="KEYREFERENCE" DisplayName="Key Ref"
DataType="System.String" />
</FieldEditors>
</telerik:RadFilter>
i tried what was suggested in one of the tutorials, but it never seems to fire this event.i also tried OnFieldEditorCreating which simply is used to invoke the class for radComboBoxes and that never fires either unless of course it's a radComboBox.
i assume that i want to do this when i click the "Add Expression" button on the RadFilter. is there some way i can switch out the DisplayName?? i've been thru every tutorial i can find, but nothing really works.
can i get some direct help? i'm a registered developer, do you guys need any info from me?
thanks
rik
Want to run something like this to switch out the Display name depending on a condition:
protected void RadFilter_FieldEditorCreated(object sender, RadFilterFieldEditorCreatedEventArgs e)
{
if (e.Editor.FieldName == "WORKORDERNUMBER")
{
e.Editor.DisplayName = "My custom text";
}
}
