Selecting multiple items from code

[Amanda]

How do i select multiple items from code in a list box or combo box?

Hi mmassey,

You cannot select multiple items in RadComboBox by default however you can follow this code library if you want to implement a custom solution.

As to the RadListBox, there is multi select functionality. Here is a sample about selecting the first and the third item using code:

private void radButton1_Click(object sender, EventArgs e)
{
    this.radListBox1.SelectionMode = SelectionMode.MultiSimple;
    this.radListBox1.SelectedIndices.Add(0);
    this.radListBox1.SelectedIndices.Add(2);
}

 
You can also use this.radListBox1.SelectedItems collection to select items instead of indices

I hope this helps. Please do not hesitate to write us back if you have further questions.

All the best,

Hi Mario,

Thank you for contacting us. This is really strange. RadListBox is one of our controls and it is present in our latest distribution and every other our release. Have you included Telerik.WinControls.UI.dll to your project?

Sincerely yours,

Hello Nick,

I see the issue, Im in the wrong section of the forum, I need the radlistbox for the web (ASP control) 

Im currently using the Telerik.Web.UI (2009.1.311.35)

So is this control currently suported only for Windows Applications?

Let me know

Thanks

Hi Mario,

RadListBox for ASP.NET Ajax is added in Q2 2009 release (version 2009.2.701) so you need to have that or a newer version.

For any questions about the Ajax controls - please use the appropriate forums.

Thank you

Best wishes,
