With the latest release of the telerik controls the Radbutton has a weird UI glitch when the TerliekMetroBlue theme is applied.
Image 1 and Image 2 has the Button enabled at design time and is working as expected.
Image 3 and Image 4 has the Button disabled at design time and is not working as expected.

I just upgraded to Telerik UI for WinForms 2014 from 2010.
I have an application with about 40 grids we build dynamically that have checkbox columns. Many of the tables feeding these grids have NULL values for the bit column. When applying a filter to a grid that has NULL values in the CheckBox column I get an error. If I modify my query using ISNULL(fieldname, 0) AS fieldname I am able to filter, but I can no longer update the bit field for that CheckBox column because it is now aliased.
Before the upgrade the filtering worked even if there were NULL values. What can I do to get both filtering and update capability on CheckBox columns that reference a bit column that contains NULL values. The underlying data cannot be changed to eliminate NULL values because a NULL represents a state other than true or false when handling data in our stored procedures.
This is the code used to create the CheckBox columns:
ElseIf objTab.Columns(i).DataType.Name = "Boolean" Then
Dim col As GridViewCheckBoxColumn = New GridViewCheckBoxColumn
col.Name = colname
col.FieldName = colname
col.HeaderText = colname
col.ReadOnly = Not (pCanWrite)
objGrd.Columns.Add(col)

I have a GridView that is bound to a binding list
BindingList<DataElementMap> DataElementMaps { get; set; }
mappingsGridView.DataSource = DataElementMaps;
I am adding a menu item to the Context Menu using the following
This works fine until I clear the data bound list. (i.e. DataElementMaps.Clear(); )
After a clear is executed the above code throws the following exception
System.ArgumentException occurred
Message=Cannot remove the specified item because it was not found in the specified Collection.
Source=mscorlib

I'm having an issue with the GridView. I'd like to be able to dynamically make appear the AddNewRow control. By default I set the AllowAddNewRow=false, but if the user clicks on The "Add New Row" menu item, I'd like for the NewRow control to appear on the grid, after I set the AllowAddNewRow=true. But I can not find a way to redraw or reload the entire grid for it to appear. Is this even possible?
The gridview is on a form, do I have to reload the whole form for this work?
I am using version 2014.2.715.40.
Thanks for the help
P.S. A little sample of the method called dynamically:
public void New()
{
radGridPilotage.MasterTemplate.BeginUpdate();
radGridPilotage.AllowEditRow = true;
radGridPilotage.MasterTemplate.AllowAddNewRow = true;
radGridPilotage.MasterTemplate.EndUpdate();
radGridPilotage.Update();
}

I am capturing scroll events (via gvLibrary.TableElement.VScrollBar.Scroll += this.gvLibrary_Scroll;) so that I can call a method on a lazy-loader class to update records in my buffer. It's designed so that the 100,000+ records won't have to load all at once, but instead we load just a few pages of data at a time. Each time the scroll is CLICKED, I am successfully able to trap the event and update my lazy-loaded queue. However, if I drag the scroll bar, the event does not appear to fire. Is there another event that I can use to handle when the scroll thumb is dragged?
Thank you,
VSmirk

Hi all,
I've set the OptionsButton Visibility to Collapsed
and indeed I don't see the small button appearing in the footer of the StartMenu but for some reason I see a default RadMenuItem appearing on the left column of the StartMenu with the text "Options <application name>".
I have also tried (with no luck)
Thank you

Hi,
I hope I'll get a reply this time (this will be my third post with no answer)
I was trying to use ExampleForms, I copied the source code of "Grouping" form into my project, it was loaded just fine.
But how to initiate the form? there is no ShowDialog method, and the show does not really show the form, so what should I do?
Dim form1 As New Form1
'form1.StartPosition = FormStartPosition.CenterScreen
'form1.ShowDialog()
form1.Show()
This is the code I used, where Form1 is a form inheriting ExamplesForm (Grouping form found in QuickStart)
Please reply ASAP.
Thank you,
Saleem.

private void myGrid_CommandCellClick(object sender, EventArgs e) |
| { |
| GridCommandCellElement gCommand = (sender as GridCommandCellElement); |
| if( gCommand.ColumnIndex == 11 ) |
| // code.. |
| } |
Simple question - I have two command buttons and wondered if it's possible to get the unique name from within the event?! can only find the column index number. gCommand.Name returns ""
Cheers
Ewart.
