I'm trying to pop up a MsgBox in a GridView's CellValidating event. like this:
The event keeps firing over and over, causing the MsgBox to appear "a million" times, and finally, the MsgBox AND the Form that contains the GridView both lose the text in their title bar.
I can use a flag like this:
...and it works correctly, as long as I am trying to navigate away from the cell to some other element in the grid. If I click on any other control on the form, I get the message twice (???) but then the focus still goes to whatever other control it was I clicked on. For example, I have a "Close" button on the form, and I want the user to be able to click it to cancel their edits and not get the validation MsgBox, but instead I want to show a "Discard changes?" type dialog. Any ideas?
PS: If possible, please provide tech specs on exactly what causes the event to fire, such as the gridview losing focus, etc.
| If e.Value.ToString.Length = 0 Then |
| e.Cancel = True |
| MsgBox("Text is required.") |
| End If |

I have the RadGridView.CellDoubleClick Handler implemented. FYI, it's being used to open the Row being Double-Clicked in a separate Form for view / edit / delete, but that's besides point. The problem is that it's being Triggered when I'm trying to expand / collapse ChildGridViewTemplate in quick succession (i.e. to quickly browse the ChildGridViewTemplate of a series of Rows). This is happening with Mouse Double-Click Speed as fast as 8 / 10 not to mention the average 5 / 10 setting. Is there a way I can detect in the RadGridView.CellDoubleClick Handler that the Cell being clicked on is a ChildGridViewTemplate Expander Cell (i.e. a GridGroupExpanderCellElement)?

I upgraded from 2009 Q2 SP1 to 2009 Q3 and have noticed some odd behavior with Autohide toolwindows that was not there before.
On the main MDI form, I have a toolwindow set as autohide. With the new release, I find that when I open a child MDI form, the autohidden toolwindow opens or animates as if I hovered over its tab. This did not use to occur. I only want animation when I hover over the tab.
On a child MDI form, I have a toolwindow set as pinned. When I hide it, hovering over the tabs does not do anything until I resize the main MDI form window. That action causes the tabs to animate normally. Again, this did not use to occur. I want animation anytime I hover over a tab.
Has anybody else experienced this?
More importantly, how can I get back the old (normal) behavior short of rolling back to Q2?

Hello muralitharan,
You use a very old edition of RadGridView. Please download and use the latest edition of RadControls for Winforms (Q3 2009). We have made many improvements and fixes in filtering.

Hello,
We met a probelm about the RadTreeNode Class of Treeview,
We find that the MouseDown Event of RadTreeNode Class disappear now and other Events such as NodeCollapsed,NodeExpanded also disappear besides only the PropertyChanged Event in RadTreeNode Class,
For example:
The code as above is work OK in RadControls for WinForm Q2 2009,but it'll occur error message when compile these codes for WinForm Q3 2009,
The error message show "Telerik.WinControls.UI.RadTreeNode' is not include the Definition of 'MouseDown'..."
This problem have led to some functions can't work of our software now.
We need your help to resolve this problem ASAP.
Best Regards.

Hi,
I have a multicolumn comboBox, it worked properly for me till i selected a row from the grid.
I have a multicolumn comboBox, it worked properly for me till i selected a row from the grid.
After selecting the row and focusing on the textbox, whenever i press any key it gives the following exception. (See Attached File.)
I also tried it in your DEMOS of multicolumn comboBox and i received the same result.
It surely seems as a bug, i hope it will be removed in Q3.

I have a RadGridView control on a form which I need to place a RadButton over the top of. The RadGridView will be disabled in code using the enabled property based on a timer. Basically a timer will disable the grid and the refreshing aspect of it. The RadButton will then be made visiable and allow the user to re-enable the grid display and thus allowing data to update again.
The problem I am having is that the RadButton docks to the RadGridView Control meaning it becomes a child of the RadGridView control. This means when I disable the RadGridView the button also becomes disabled.
Do you have any idea how I can have the button overlapping the RadGridView Control without it becoming a child of the control?
Regards
Neil
