RadGridView Columns sometime disappear.
For example:
I have set BindingSource, deleted not needed columns (leaving 2 TextBoxColumns on the GridView) and then added LookupColumn. When I have clicked OK button, the LookupColumn disappeared.

I have a RadDock control that contains Tool Windows, Document Windows and Shaped Forms.
I want to be able to display a list of hidden windows and restore them to their pre-hidden state.
Questions :-
- Is there a list of these windows somewhere or do I have to track the windows that are hidden?
- If I need to track the windows that are hidden how do I do that?
- Any suggestions as to which control would be best suited to display the list of hidden windows, i.e. if you've done it before, used a particular control and it worked well
Thx

18
0
0
0

0
21

I know there is supposed to be an EptyValue property that approximates the empty (0 ???) values, but how can i use it ?
Currently i don't see any results on the chart
I use a bar chart and as it is now, the 0 values do not get approximated

It drives me absolutly crazy when I make a change in the design mode and the change doesn't show up when I debug it. Where does Telerik store the settings for the UI at? I know its a binary file somewhere, I have came across it before and I know If delete it, it will be rebuilt with the latest settings. I hate spending 20 mins having to trick the Telerik stuff into working and I am a little frustrated. I know I could explain in greater detail what is going on but first I would really like to know where the settings file is.

The following link points to a Visual Studio 2008 VB.NET project that demonstrates some grid editing problems. I need advice on these problems.
http://www.glt1.com/gl/misc/GridView20091207.zip
Here are three sets of steps to produce the problems:
http://www.glt1.com/gl/misc/GridView20091207.zip
Here are three sets of steps to produce the problems:
Run the project
Click in the "Row Text" column of the third row. The row is highlighted as expected.
Click again in the "Row Text" column of the third row. The cell goes into edit mode. The row size decreases so that the cell editor is only a single line. The row SHOULD have remained the same size.
Click in the "Row Text" column of the first row. The cell goes into edit mode as expected.
Click in the "Row Text" column of the third row. The cell goes into edit mode as expected, while remaining the correct size. It seems to stay the correct size from this point on, that is, the downsizing-to-one-line problem seems to occur only when going into edit mode for the first time.
Run the project
Click in the "Row Text" column of the third row. The row is highlighted as expected.
Click again in the "Row Text" column of the third row. The cell goes into edit mode (and the row sizing problem is evident once again).
Click just to the left of the first letter ("R") in the "Row Text" column of the third row. The cell text un-highlights and the caret is positioned at the beginning of the cell text as expected.
Press the left arrow key. The cell focus moves to the first column (skipping the read-only second column) as expected.
Press the left arrow key again. The cell focus moves very briefly to the "Row Text" column of the second row, but then quickly moves to the checkbox column of the second row. The cell focus SHOULD have stayed on the "Row Text" column of the second row.

Click in the "Row Text" column of the fourth row. The row is highlighted as expected.
Click again in the "Row Text" column of the fourth row. The cell goes into edit mode (and the row sizing problem is evident again).
Click in the "Row Text" column of the third row. The cell is focused as expected.
Click anywhere on the third line of text in the "Row Text" column of the third row. The cell text un-highlights and the caret is positioned on the third line of text as expected.
Press the up arrow key. The caret moves to the second line of text in the cell.
Press the up arrow key again. The cell focus moves to the "Row Text" column of the second row. The caret SHOULD have moved to the first line of text in the "Row Text" column of the third row.

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?
