Can we change RADGridView Header Height at runtime?

Situation is like this:

I need to display following like RadGridview in Windows Application.

.......... |              Col1        |        Col2         |         Col3     |................
.......... |Col11|Col12|Col13| c  | c | c | c | c  | ....................
                                         | o  | o | o| o | o |
                                         | l   | l  | l | l  |   l |
                                        | 21 |22 |23|24 |25 |
                                       
1) Is that possible to display column header vertically?
2) If (1) is not possible then can we change Header height?
3) can we give ToolTip to each column header and its sub-column header?

Probably attached image may clear the idea.
Is there any solution for this situation?
                                       
Thanks.

Hello yashpal gohil,

Thank you for writing.

You can change the text orientation by using TextOrientation property in ViewCellFormatting event. Also you can set the header row height using the TableHeaderHeight property. Please, consider the following code:

this.radGridView1.GridElement.TableHeaderHeight = 100;
 
void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement is GridHeaderCellElement)
    {
        e.CellElement.TextOrientation = Orientation.Vertical;
        ((GridViewTableHeaderRowInfo)e.CellElement.RowInfo).Height = 100;
    }
}

As for the ToolTip question, I recommend you check our Demo application and in particular GridView/Tooltips example.

Write me back if you have any other question.

Sincerely yours,

Hi Martin,
thanks for your effort in solving problem of mine.

Here I want to say that even using your code I can't get desired result.

Any way I get tooltip for column and textfields using some other article.

When I change orientation of text direction of each character rotates! thing I don't wont.

And height of header I can't increase with various methods including mention by you.
This may because I have done Grouping with column.

Please check these details.

Thanks,
yashpal

Hi yashpal gohil,

I have tested my code with latest Q3 2009 release and it works for grouped RadGridView as well. If you are using older version I highly recommend that you to download the latest one and give it a try. It has a numerous fixes and improvements.

Martin,

 

Does your full example use the ColumnGroupsViewDefinition like yashpal is trying to do?  Like yashpal, I've also found that the RadGridView simply ignores the TableHeaderHeight property when the grid uses the ColumnGroupsViewDefinition.

I'm using 2009 Q3 SP1.

Hello poiuytrewq poiuytrewq,

Actually, ColumnGroupsViewDefinition does not support changing the header row height. We will include this functionality in some of the future releases. Let me know if you have other questions. 

Kind regards,

Hi anand,

No, currently this feature is not available in RadGridView and we have not scheduled this task. I added it as a feature request in our PITS system where people can vote and when more people request the same functionality we will raise its priority.

If you have any other question, we will be glad to help.

To fix the height of the header row, create a new style which you can store in your resource dictionary:

<Style x:Key="GridViewHeaderRowStyle" TargetType="telerik:GridViewHeaderRow">
        <Setter Property="Height" Value="40"/>
   </Style>

 ‚Äčthen set the HeaderRowStyle with the newly created style:

 <t:RadGridView x:Name="MainGrid"
                           HeaderRowStyle="{DynamicResource GridViewHeaderRowStyle}"  >

Hello Eric,

This forum concerns Telerik UI for WinForms, while your answer seems to be for another product. Just wanted to let you know.
