I have GridView with ContextMenu, i added to this ContextMenu several options after the user click right click on item from my GridView  and i want to know how can i change the color of the item that the mouse is in, you can see he default color in the attach screenshot

I set the datasource of multicolumncombobox everytime dropdown opening event is fired.
But on the first instance, it only show the header and a vertical scroll like 1st.png attachment. It did have rows since if I press downbutton, a row will be selected
while on the second instance and later, it works like 2nd.png attachment.


Any suggestions?

Hi,
I have a radGridView control with two columns, the second one should contain string values in every cell except for the last one which should be a checkbox. I'm not able to put the checkbox inside the cell. I've tried using the "CreateCell" event of the gridview in this way:


The problem is that e.Row.RowInfo.Index is not the "absolute" row index but it's relative to the displayed cells. So, if I have a resized form the result of e.Row.RowInfo.Index could be any number between 0 and rows.Count.
Can anyone help me? Thanks.

Hello everyone

I'm trying to sort a RadGridView by clicking a header cell. The name of the column which should be sorted is "priority" and it's type is double. I have some other column which has different values. All these columns together build a "priority number" like 1.0, 2.0, 2.1 etc. And this "priority number" is in column called "priority". And now I'm trying to sort the priority column. It shouldn't matter which column header i click, it just have to sort the priority column. I tried this code:

private void radGridView1_CellClick(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    if (e.RowIndex == -1)
    {
        if (e.Column.Name == "va")
        {
            if (radGridView1.Columns["priority"].SortOrder == RadSortOrder.Ascending)
            {
                radGridView1.Columns["priority"].Sort(RadSortOrder.Descending, false);
            }

            else if (radGridView1.Columns["priority"].SortOrder == RadSortOrder.Descending)
            {
                radGridView1.Columns["priority"].Sort(RadSortOrder.Ascending, false);
            }

            else
            {
                radGridView1.Columns["priority"].Sort(RadSortOrder.Ascending, false);
            }
        }
    }
}

But it doesn't work. When I hit "va" column header, it sorts the "va" column and not the "priority" column. But in debugging mode I can see it goes through this code. Can anyone please tell me why it's not sorting "priority" column?

Thank you

When using a RadCalendar and if a user clicks on the currently selected date, the SelectedDate value of the RadCalendear will change to the RangeMinDate.  I'm currently using version 2011.3.11.1219. Please let me know if I'm missing something or a common work around for this.

Thanks,
Chris

Hi:

I have a problem modifying mi RadForm Title Bar Font. I'm trying to do by design, but it does not apply, i think its because im using Office Silver theme. Anyway, there are form propperties that I could change by code just when the form initializes, like the Icon and Image (thanks for that hit :)   ); but the font it says is Read Only:

Is there a way to change the font just for the RadForm Title Bar?

Thanks

Hi,
I had some issues trying to load different raddock's layouts containing distinct numbers of Tabbed Documents. This error always occurs on as specific situation, I'm gonna explain considering this two layouts:
LAYOUT1 = 4 Tabbed Documents
LAYOUT2 = 3 Tabbed Documents

First I load LAYOUT1 on my raddock and it creates 4 new Documents without errors. Then I load LAYOUT2 and apparently raddock re-use 3 opened documents and dispose one, that's ok. Finally, when I try to load LAYOUT1 again, I get a disposed object exception as below. I simulated this situation on Q2 2013 SP1 Examples (Dock\Serialization) and got same error (this example only uses ToolWindows, but when you dock the control filling the parent it becomes a Tabbed Document property). I really need that funcionality to by your product, thanks for your attention.

Hi,
I need to change my application's font dynamically,when I set the font of main window without setting theme everything works fine
but unfortunately when I set the theme changing font not working.
Is there any way to change the font of controls dynamically after setting theme?

All the rad controls and their groups are gone from my toolbox.

I spent 2+ hours repairing VS2010 and loading updates.  I then ran the telerik toolbox configurer and they were there.  Then, while changing the Text property of a Telerik control, VS crashed.  When I reopened the project the tools were all gone from the toolbox again.

What is going on?!  This is costing me a huge amount of time!

How can I fix this quickly?
