How do I change column headers at runtime?

[Jerry Kurata]

Hi,

We have a requirement to allow users to change the column header formatting and text at runtime.  Changing the text appears easy enough, but I am not sure how to change the formatting.  Users need to be able to set the Font Family, size, bold, italics, underline and color for the Column header.  Do you have a sample showing this?

Thanks,
Jerry

Hello Jerry Kurata,

 You can insert a TextBlock in the column's header and bind its various properties.

<telerik:GridViewColumn>
  <telerik:GridViewColumn.Header>
    <TextBlock Text="{Binding HeaderText}" FontFamily="{Binding HeaderFont}"/>
  </telerik:GridViewColumn.Header>
</telerik:GridViewColumn>

Kind regards,

Hi,

This change created a problem with exporting the data to excel, word, etc.  All column title appears as the "windows. ... TextBox".
How can I fix this?

Thanks,

Jerry

Hello Jerry Kurata,

 You need to handle the ElementExporting event of the RadGridView:

private void radGridView1_ElementExporting(object sender, GridViewElementExportingEventArgs e)
{
    if (e.Element == ExportElement.HeaderCell)
    {
        if (e.Value is TextBox)
        {
            e.Value = (e.Value as TextBox).Text;
        }
    }
}
