HI,

We have many columns to be displayed in UI, we are displaying static columns in UI using telerik on page load, which is taking a lot of time. Is there anyway where we can delete unnecessary columns before page load so that loading time will decrease. Please help me out here, Thanks in advance.

Thanks and Regards,

Raj Kamal Singh Rathore.

Hi Raj,

A possible solution is to hide the column OnPreRender event handler by using Visible property of the columns. This way the columns will not be rendered on the page.
protected void Page_PreRender(object sender, EventArgs e)
{
    RadGrid1.MasterTableView.GetColumn("Column2").Visible = false;
    RadGrid1.MasterTableView.GetColumn("Column3").Visible = false;
}

Keep in mind you can loop through the columns collection and hide the one which you do not want to display.
