TableBodyElement

Hi,

I have a master/child table were i like to remove the border around the child table or just resize the child.
I found a thread that had some of the same elements that i was looking for, but the solution did not work.

One of the part that did not work was this:

if (e.CellElement is GridDetailViewCellElement)

{

GridDetailViewCellElement cell = e.CellElement as GridDetailViewCellElement;

cell.ChildTableElement.DrawBorder = false;

cell.ChildTableElement.TableBodyElement.DrawBorder = false;

}

The TableBodyElement is not in the property list of ChildTableElement.
Is there another way to remove the border around the child.
And is there a way to resize the child grid?

Regards
Svein Thomas

Filtering Question

My filter image and sort image seem to overlap in the column headers of my grid. I'm using the Office2010 theme.

Also, when the user has selected a filter, there is no visual indication that the data in the grid is filtered. Is there a way to update the filter icon so that it "appears" filtered?

Adding an image to the GridRowHeaderCellElement

I have a radgrid that I want to add an image to the GridRowHeaderCellElement ImagePrimative dynamically. I don't want to ad the image unless a certain condition is met. I don't think conditional formatting will work because the GridRowHeaderCellElement does not contain any data. The condition will be calculated on a hidden cell in the row. I want the image in the GridRowHeaderCell to show graphicly that this record contains certain other data, sort of like a flag.
How do I access the GridRowHeaderCellElement Imageprimative property to assign an image while looping through the rows? I am using hierarchial data so the expander cell is occupied. I need access to the header or Indent cell properties for each row.

Ctrl+enter on check box header cell

Hi,

I'm using the checkbox header class from here: http://www.telerik.com/support/kb/winforms/gridview/add-check-uncheck-all-check-box-in-the-header-cell.aspx

I need to handle users pressing Ctrl+enter to perform an action on all selected rows. The problem I am having is this: if you press Ctrl+enter after checking the check box in the header cell, the check box interprets this as a click and de-selects all the rows in the grid, and consequently no action is performed.

If I select another cell after checking the header check box, it works fine. I have tried selecting another cell programmatically, but the problem still occurs.

How can I prevent Ctrl+enter from triggering a click on the checkbox and still have it raise the Datagrid.KeyDown event?

Thanks,
Matt

Collapse RadRibbonBarGroup not working

I am using WinForms Q2 2010 SP2 RadRibbonBar control. According to http://www.telerik.com/help/winforms/ribbonbar-end-user-capabilities-collapsing-the-ribbonbar.html, the right-most RadRibbonBarGroup will collapse to a simple rectangle when the form containing the RadRibbonBar is resized smaller than the RadRibbonBarGroup size. This isn't working for me. When I resize the form to a smaller size, ALL of the RadRibbonBarGroups collapse AND none of them collapse to a simple rectangle. How do I manage this programatically?

Mark Multiple Answers

I think a thread initiator should be allowed to mark multiple threads as answers, because many times different approaches that yield the same results are mentioned in different threads by different people.

Thanks

RadMenuItem Enabled property bug (2010 Q3)

After upgrading to the 2010 Q3 release, RadMenuItems will no longer update their display when changing Enabled from false to true. In other words, the menu item becomes clickable as it should, but it still looks disabled (the text is gray and there is no hover effect on the fill).

Help?

NullReferenceException when tabbing out of the last cell on a row.

Hi guys,

I have a grid binded to a Linq datasource. Binding is done by hand/code when populating data.
Some of the data needs a editable grid, and some dont. I therefor switch between two datasources and switch between making the grid readonly and writable.

When its in writable mode, i'm able to write data into the cells and a new row is added automatically if move to another row (with the arrowbuttons) or click outside the row, but if i tab out of the last cell in the row i get an NullReferenceException ("Object reference not set to an instance of an object")?. I use the latest version of the grid (2010.3.10.1109).

Any idea?

Regards
Svein Thomas
