I have a column that is defined as GridViewCheckBoxColumn I'm able to check the checkboxes and the code behind does what it's suppose to do. My problem is when I filter another column the checked rows stay checked but the data for that row has changed. When I try and do it programmically every time I do the following

    
            this.radGVTables.Rows[i].IsSelected = false;

The radGVTables_ValueChanged event fires and it is looking for the rowindex.
But since it was the filter that was selected the rowindex is -1.

1. Is there a way to change the rowindex or cycle through the rows?

2. Is there a way to clear out all the checked checkboxes?

3. How have others handled Checkboxes and Filters?

Thank You

Jerry

Radform - Context Menu Appearing "Behind" windows taskbar

Hey Telerik,
I wanted to ask - have you seen any issues with this? I have a Radtreeview inside a RadRibbonForm, and when I show a large context menu for the point in the treeview I'm clicking, it often will show "behind" the windows taskbar. This only seems to occur after the RadRibbonForm has been resized/maximized, minimized.

Can anyone let me know if you've seen this and if you have a work around? We're running Radcontrols for Winforms 2008 Q3.

Thanks!

Jim

RadTitleBar on ShapedForm: Theme problem

Hi,

I have the problem theming a RadTitleBar on a ShapedForm.

What I did:
0. created a new default WinForm-Project
1. added all the Telerik-dlls to the project and changed the Form to a ShapedForm
2. added a RadTitleBar
3. added the file RadTitleBarVista.xml from the Telerik VS2008 C# Examples project as a embedded resource.
4. added a RadThemeManager and added the xml-file to it (StorageType: Resource)
5. selected the now appearing Vista-theme to the RadTitleBar: the design view changed and the RadTitleBar has the Vista-Theme applied.
6. Compiled and started the application: The RadTitleBar now has the Office2007Blue or default-theme(???)
7. I also tried setting the ThemeName to "Vista" in the FormLoad-Method with no effect.

Fyi, I'm using VS 2008 on Vista (32 bit).

How can I get the Vista-Theme on the RadTitleBar? What am I doing wrong?

Thanks in advance!

[Solved] Cells' values

Hi everybody.
I have a question. In the code below I'm trying replace cells with a specific value with an empty string, but this step changes also the values in the database table for corresponding cells.

GridViewRowCollection rowCollection = someGridView.Rows;
foreach (GridViewRowInfo info in rowCollection)
{
    if (info.Cells["someColumn"].Value.ToString() == "someValue")
    {
         info.Cells["someColumn"].Value = "";
    }
}

How can I avoid such a behavior, without creating another foreach loop in order to restore previous values?
Thanks in advance.
Frank.

Row Backcolor

I would like to set the backcolor of a row based on data within a dataset when I set the dataset then I want to everything to work as normal. The only way I can figure out how to do it is use the "RowFormatting" but everytime you move your mouse over a row the "RowFormatting" function gets called and it does the redraw like it is a brand new row. Is there anything like a rowinitialize event. or how do I set the hover color

Combo Box Alternate Text Display

Hello,

When there is no item selected then the dropdown should display the alternate text i.e."Select Name" (or any other). On clicking the dropdown that text should disappear or appears when the item is not selected in Light color with italic font style.

Thank you,

Ajay
