GridViewCheckBoxColumn CheckBox Size

[Nadia Sangiovanni]

Hi Support,

We are presently designing a touchScreen application. The size of the check box in a GridViewCheckBoxColumn is too small.
How can I change the size of the check box in a GridViewCheckBoxColumn?

Regards,
Nadia

Hello Nadia,

Thank you for writing.

The easiest way to increase the size of the check box is to assign an image to the CheckMark. Attached you can find a sample project demonstrating this.

Alternatively, you can increase the size of the default check mark:

void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    GridCheckBoxCellElement checkCell = e.CellElement as GridCheckBoxCellElement;

    if (checkCell != null)
    {
        RadCheckBoxEditorElement el = checkCell.Children[0] as RadCheckBoxEditorElement;
        el.Checkmark.CheckElement.UseFixedCheckSize = false;
        el.Checkmark.CheckElement.MinSize= new Size(32, 32);
    }
}

I hope this helps.
 
Kind regards,

Hello Stefan,

Thank you for your response. I use the suggested code and everything as expected. I had to remove the line with the UseFixedCheckSize because this function don't seem to exist for GridCheckBoxCellElement.

Also, I didn't find the sample project demonstrating how to assign an image to the CheckMark.I guess you forget to attach the file.

Best Regards,
Nadia

Hi Nadia,

Thank you for your reply.

Indeed, I did not attach the sample. Please excuse me for the omission. You can find the sample attached to this post.

As to the missing property, it exists in the latest version (Q3 2012), so I assume that you are using a previous one and this is why it does not exist.

I hope this helps.
 
All the best,
