Hello,

How do you get and set the selected index on a RadGridView control.
There is no such thing as .SelectedIndex on the grid.

Thanks,
Stephan

Hi Stephan,

Thank you for this question.

You are correct, RadGridView doesn't have a SelectedIndex property. RadGridView presents hierarchical and grouped data. Because of this, using the SelectedIndex property by itself would be misleading.

In case of flat (nonhierarchical) data, you can use the IndexOf property of the Rows collection of RadGridView. This value will represent the index of the currently selected row in the top-most level of the RadGridView.If you would like to get the index of a row that is nested deeper in the hierarchy, please use the corresponding GridViewTemplate.

Refer to the following code snippet:

int selectedIndex = this.radGridView1.Rows.IndexOf(this.radGridView1.CurrentRow); 

I hope this helps. Do not hesitate to write, if you have further questions.

All the best,
Jack

I too needed to get the index of the selected (or current) row for non-heirarchtical sets, and I tried what you mentioned, but it does not compile:

I am using VS 2008, and running the latest version (as of yesterday) of the telerik controls.

Here is the error:
Error 2 Argument '1': cannot convert from 'Telerik.WinControls.UI.GridViewRowInfo' to 'Telerik.WinControls.UI.GridViewDataRowInfo' C:\Source\WebPortal\Developers\sculver\EnhancedAttachmentControl\EnhancedAttachmentControl\EnhancedAttachmentControl.cs 210 55 EnhancedAttachmentControl


It seems that the indexof method expects a DataRowInfo and the CurrentRow is only a RowInfo type.

Is there some other method to accomplish this without iterating through the list?

Hello sculver,

Thank you for writing.

You have to cast the current row to GridViewDataRowInfo. Please, review the code-block below as a reference:
 
if (this.radGridView1.CurrentRow is GridViewDataRowInfo) 
    int selectedIndex =  
        this.radGridView1.Rows.IndexOf((GridViewDataRowInfo)this.radGridView1.CurrentRow); 

I hope this helps. If you have other questions, do not hesitate to contact me again.

Hi Martin,

 I know this is a very old post but I came across it while trying to figure out how to get the index of a GridViewRow. Am I missing something, because the RadGridView that I am working with in WPF doesn't have a Rows property or a CurrentRow property.

Hello David,

Please note that this is the WinForms forum and the WinForms grid has different properties. This is why I would ask you to post your question in the appropriate forum section: Forum threads about GridView UI for WPF

Thank you for your understanding.

Hi Fariba,

Thank you for writing.

You can get the child rows index from the template:
if (radGridView1.CurrentRow.HierarchyLevel == 1)
{
     var index = radGridView1.Templates[0].Rows.IndexOf(radGridView1.CurrentRow);
}

I hope this will be useful.

Hi Stephen,

The following article shows how you can set the current row/column: Accessing and Setting the CurrentCell. 

I hope this helps. Should you have any other questions do not hesitate to ask.
