[Solved] How to hide columns after binding data

Hi,

I have a gridview with datasource defined and I just want only some of the columns to be visible. But when I bind data using DataSource property, my design time column visibility settings are lost and all columns are shown.

I'm using Q2 2009 trial version, but in Q1 everything works fine...

Thanks for solution.

subclass RadGridView results in grid not rendering correctly

If I create simple class that extends the RadGridView:

public class MyGrid : RadGridView

{

}

If I put this grid on my form, the grid just renders text, the column headers have no background, either do the cells. How can I subclass the RadGridView and still have the default styling apply?

[Solved] BackColor Grid

Hi,

I'm a beginner with the gridview. How can I change the backcolor of the grid?
radgridview1.backcolor = Color.Yellow doesn't work :-(

I found in the themebuilder the property: GridTableBodyElement. But I did find a snippet, how can I use it.

Greetings

[Solved] ScrollToRow Index Out-of-Range Error

Hello,

I'm getting an index out of range error on a scroll-to command that doesn't seem to make sense. In the block of code just before the ScrollToRow command, I am setting the datasource equal to null, and then re-initializing the datasource. Next, I am checking if the number of rows exceeds the number that can be displayed, and if so, I wish to scroll to the bottom to display only the last rows. Here is the code:

    
                                    grdRecords.DataSource = objRecordList; 
        
                                    AlignRecordGrid(); 
        
                                    int iVisibleRows = grdRecords.GridElement.RowsPerPage; 
        
                                    if (grdRecords.Rows.Count > iVisibleRows) 
        
                                    { 
        
                                        grdRecords.GridElement.ScrollToRow(objRecordList.Count - iVisibleRows + 3); 
        
                                        //grdRecords.FirstDisplayedScrollingRowIndex = objRecordList.Count - iVisibleRows + 3; 
        
                                    }

I run into an error here every time saying that the index is out of range. This is strange to me since in the example, the number of rows is 21 and the rows per page is 14. When the gridview is a windows gridview, the commented out line did the trick just fine.

Any help would be appreciated!

Thanks!
Jeremy

[Solved] Breaking Change in 2009 Q2: names of dynamically added controls must be uniqe

Q2 throws an exception when I try to add 2 RadButtons with the same name to a RadPanel.Controls Collection.
This was possible in Q1, had to add code to generate uniqe names.

Not documented AFAIK. Please update your documentation with all the breaking changes introduced in 2009 Q2.

Kind regards

MultiColumn Combo Box read only text

Hello,
I am using the latest version of the controls and I'd like to be able to set the text of a MultiColumn Combo Box to read only.

'm using the combo for a multi column selection so the users can see more information on a row, but the text should be read only. In your demo also it is possible to freely type into the text area.. I've had to get round it like this.. which is hardly elegant..

Private Sub ComboVatRates_TextChanged(ByVal sender As System.Object, _

ByVal e As System.EventArgs) Handles ComboVatRates.TextChanged

Dim rowInfo As GridViewRowInfo = DirectCast(Me.ComboVatRates.EditorControl, RadGridView).SelectedRows(0)

If Not rowInfo Is Nothing Then

Me.ComboVatRates.Text = rowInfo.Cells(1).Value.ToString()

End If

End Sub

RadMenu Hot keys not working

Hello Telerik,

I am using RadMenu in my winform application and want to use hotkeys (e.g. Alt + A) for them. I try use the CommandBinding property for the menu items and use it as described on the support forum.

<admin>Obsolete Command Binding Link</admin>

The hotkey for a specific menu is only working when the mouse pointer is above it and is not working from any where else in the form (when mouse is not over it). So could you please help me in this regard and provide me with an example code for VB in VS2005.

Regards,

Haroon
