visible=false, no item index?

[Phillip]

I'm trying to hide a bunch of columns and display a bunch of columns when clicking print.  However, it appears that if the item is visible = false then it does not have an index and therefore I can't use showcolumn.  Anyone know a way around this? 

MasterTable.showColumn("0");

<Columns>
    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn column"
        UniqueName="PrintColumn" Visible="False" >
        <ItemTemplate>

Hello,

 You can access the invisible column by its ColumnUniqueName.Try the following code snippet to show the invisible column on button click.
CS:

protected void Button1_Click(object sender, EventArgs e)
{
  foreach (GridColumn col in grid1.MasterTableView.Columns)
  {
    if (col.UniqueName == "FirstName")
     {
       col.Visible = true;
     }
  }
 grid1.Rebind();
}

Thanks,
Princy.

Princy,

Thanks for the reply, but I'm trying to this with javascript on button click.  Thanks

Hello Phillip,

You could achieve your scenario by following the steps below:

• Instead of Visible="false" use Display="false" for the grid column, this way the column will be rendered and could be accessed client-side.
• Call the MasterTableView showColumn method with the appropriate column index.
