Set GridBoundColumn filter textbox tooltip/label for?

[Jay]

I need to provide accessibility cues for the textbox of the standard column filter. It looks like I could do this using a FilterTemplate which has a hidden asp:Label with its AssociatedControlId set to an asp:TextBox. However, I would then have to implement all the filtering myself rather than using what the grid provides.

Is there a way to associate a tool tip or something with the textbox provided by the standard filter? Can I somehow access the standard filter's text box?

Thanks.

Hello Jay,

You can get reference to the TextBox control associated with the filter for a given column by handling the server-side ItemCreated event of the grid. The code snippet bellow demonstrates how to get reference to the TextBox for the column with UniqueName "FirstName" (as an example):

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridFilteringItem)
    {
        GridFilteringItem item = e.Item as GridFilteringItem;
        TextBox firstNameFilterTextBox = item["FirstName"].Controls[0] as TextBox;
        firstNameFilterTextBox.ToolTip = "changed tool tip";
    }
}

Hope that helps.
