Hi everyone,

in the attached file you see the exception I get (Sorry, it's in German). The Problem with this exception is, that it appears not every time by doing the same steps. So we can't say definititly what step let this exception occures.

 

So here are the circumstances:

  • RadGradView with some columns (4-5)
  • Binding on a DataTable
  • ReadOnly  = false

So when from a dialog a value is puttin' in one of the cells, the problem somtimes appears.

I downloaded the source code and searched a bit. (In GridView_WPF.sln: GridView/Cells/GridViewCell.cs) 

In the method 'PrepareCellToolTip' the second time when ToolTipService.GetToolTip is called:

var visualElementToolTip = ToolTipService.GetToolTip(this);
var isCellErrorToolTip = this.CellErrorMessage != null && this.CellErrorMessage == visualElementToolTip;
 
 var row = this.ParentRow as GridViewRow;
 var rowToolTip = ToolTipService.GetToolTip(row) ?? string.Empty;

Before row is hand over to 'GetToolTip()',  there should be proved if it isn't null, right?

Hi,

I am using RadGridView in WPF application and binding it to a DataTable view. For my RadGridView I have set AutoGenerateColumns as "True" (to get my columns automatically).
 
Problem: In DataTable object (which I am binding to RadDataGridView) I have one DateTime column. In RadDataGridView it only shows Date calender in the dropdown for picking date, but no time. More over I want to change date format for DateTime column. As AutoGenerateColumns  is true, I don't have any control over the columns. Can anyone please show me how to show RadDateTimePicker in RadGridView column when AutoGenerateColumns is True?

My XAML code for RadGridView  is as below:

<telerik:RadGridView Grid.Row="1" AutoGenerateColumns="True" ItemsSource="{Binding ManualDataTable}" IsReadOnly="False" CanUserDeleteRows="True"  Name="radGridViewManualData" ShowInsertRow="True" />

Any help will be highly appreciated.


Regards,
Moon

I am trying to set the row height of the RadGridView element to fill the whole space of the grid instead of showing blank space when the number of rows is less than the height of the grid, the problem is I couldn't find a simple way to do this without many complications and performance issues using different events to set the RowHeight property when the size is changed for the grid. How to achieve this?

Hi everyone,

 

I'm using the OpenStreetMapProvider for a long time now, but since this monday I have a problem. Instead of the real map tiles see the the pictures you can see in the attached file. I don't understand whats wrong here. I'm not using MapQuest. And Openstreetmap is still free to use.

 

Can someone tell me how to solve this, so I can have my map back?

 

Best Regards

Erich

Is there any way to delete a custom list style?

These commands seems not working and will create some null reference exception on next opening of manage styles dialog.

                document.StyleRepository.Remove(listStyle.StyleLink);

                document.ListManager.UnRegisterListStyle(numListStyle);

                document.ListManager.UnRegisterListStyle(listStyle);
