Hi All,

Is there a way to access a control that is in the first cell of a selected row during gridview selectionchanged event?

My first cell is a GridViewColumn with a combobox. It's not bind to the datasource.

In the the AddedItems or RemovedItems property of e I have the buisness object but nothing regarding the first cell/column that is not part of the datasource.

What would be the easiest way to change the selected item in the combobox when selecting a row.

I need to change the selected value in the combobox for the newly selected row and for the ex-selected rows.

thank you

Wrapping the Carousel

Maybe I'm missing it, but is there a setting on the Carousel that tells it to loop around when it gets to either end of the list?

How to enable dragover Auto Expand

We are using the Radtreeview to show some virtual folders. We have a require ment to drop files inside the treeview.

ie, the end user can drag and drop the items from the windows explorer to the RadTreeView. But the treeview items does not automatically expands when the user drags the file over the treeview item.

We just like to do the same of windows explorer treeview drag drop functionality. The windows explorer (win forms) treeview automatically expands while drag over an item .

How to achive that in RadTreeview?

Hide Expand/Collapse

Hello,

My application looks like your example "firstlook".
I want to be able to hide expand/Collapse image if there are no child records. I saw the example N° 101300_HideExpandButton.
Today , is there an easier way to hide expand/Collapse ? (because this post dates september 18th, 2008)

Thanks.

Control Expander on SelectionChanged event

Hi,

I have WPF 2009 SP2 (2009.2.701.35). I am attempting to control the expander (+ - ) on the grid. I use the following event

PreviewDataRecordCreate for the intialization of the grid to control the expander which works well. However i would like to validate the expander when the user selects the row (selectinchanged event)
I have tried to cast to the ExpandableDataRecord but this is always null. I would like validate that the expander is valid i.e. i do have data for the child grid. I am currently calling a rebind of the grid view but this does not help. I dont want to remove the row and re-add it as that seems to be a hack.

Secondly is there an event when the user clicks on the expander (+-) as this does cause a selectionchanged event?

The last question is that there is allot of classes marked as deprecated such as ExpandableDataRecord is there mechanism to look at which classes we should use instead as the forum posts would refer to the old classes?

Kind Regards,

Clinton

it is possible to not display a value?

I mean, suppose you have a line graph with 20 value but i don't want 4th and 8th values so that my line is broken because 4th and 8th values are invalid.
It is possible?
