Hi,
I have a databound gridview. There is a reset button on the form which should revert the gridview changes. I have checked that the datasource reverts back, but the gridview appears as is...
Can you please give me a solution for this
Thanks
Deepak

I have setup a hierarchical RadGridView with a 2 command button columns on the master rows (remove, and add new child row), and the child rows have 1 command button, remove.. When adding a new child row, a modal form is shown and after the info is filled out and saved, the gridview was completely rebound and reloaded.. The same thing occurs when I hit a remove button, except that the row is deleted.. I originally had this working in the Q3 2007 version without any problems, but in upgrading to q1 2008, my same code no longer works..
I realize my original setup was probably less than correct, and i now have the gridview setup with 2 global BindingLists.. One is bound to the mastertemplate, and the other is bound to the childtemplate.. Now when I add a new child row, I just add the proper object to the child bindinglist variable, and it automaticaly shows up in the gridview (much better!)..
The problem I am having is that when I try to remove/delete a row [bindinglist.removeat(index)], I get the following error:
"This row has been removed from a table and does not have any data. BeginEdit() will allow creation of new data in this row."
I somewhat understand that the gridview is still bound to this object somehow.. What I don't understand is how to go about correcting the issue..
Any help would be appreciated, including any suggestions for how to accomplish refreshing the data on my gridview without the bindinglists

I am building a VB.NET WinForms app and am using Telerik Controls for Winforms 2009 Q3. My users like the themes that ship with the controls with the exception of the fonts (which they want larger). My solution was to edit the themes (so they would be larger at design-time as opposed to updating them at runtime).
Here is what I did:
- Download the source code
- Update the font sizes (I just updated the font size of the Button, then changed the theme name to "TestAqua")
- Compile the theme
- Import the resulting dll into my app as a resource
- Set its build type to be embedded
- Build the app
- Add a RadThemeManager to a form (for now, RadThemeManager1)
- Add the theme to RadThemeManager1 (Change the location of the theme file, if needed)
- Build the app again
Next I expected to do be able to set a RadButton's theme to TestAqua, but that theme was not available. Nor would it work by setting it in code. As I stepped through the code, I discovered that RadThemeManager1.InstalledThemeNames had a size of 1 (good), but that theme name was set to Nothing (that seems bad).
One of the reasons we got Telerik controls was that we thought this would be easy to do (and it still seems like it should be easy), so I'm hoping that I'm just not leaning in the right direction when I hit enter, or something. :-)
Thoughts?
PS If my original post shows up, sorry -- somehow it has not yet made it to the forum....

Hi,
I am planning to have .chm file in my application.
A help icon on every tab to say what each tab stands for.
Do you have a suggestion as to how i can implement it. Is there a novel way to do in Telerik. I havent found any reading matter on it yet. Will i have to do it the old fashioned windows way?
Thanks in advance.,

Is there any way to use a theme with a color blend on just some forms (or for example just the Rad message box) without affecting all the other forms that are using the same theme? In other words, do we have to create separate themes if we want the colors to vary for different forms?

I was wondering if there was a way to change the way the grid sort is
handled? For example when the user clicks the header to sort and if
one of the rows in the column is empty to not have it sort that row,
but rather have anything with an empty row always come up last?

Hi,
I'm trying to create an interactive graph for a large data source.
When trying to bind the data source (list of Int) with about 50K data points, the application gets stuck on radChart1.DataBind();
What is the recommended way to display a graph (line chart) for such data?
Thanks,
Yoni

Hello,
I have a question concerning Theme: I have created a theme for my project. I have changed the look and feels of all controls and it's very good. Now, I would like to have a unique font in my projet.
It's possible to do that with theme? If yes, how can I do that?
Best regards,
Nicolas.

Hello,
Problem with programmaticly setting the height of the group header (q3 2009).
Is the ViewCellFormatting event the place for adjusting the group header height?
Trying things like:
if (e.CellElement.RowInfo is GridViewGroupRowInfo)
{
int height = Convert.ToInt32(Mo.LetterType.Height);
if (height > 10)
{
e.CellElement.RowInfo.Height = height + 10;
}
else
{
e.CellElement.RowInfo.Height = 20
}
}
Anybody got a suggestion?
Kind regards,
Tim van Rooijen
