Dynamically adding link button in RadGrid Header

[Pratap]

Hi Telerik team,


I am trying to add htmlbutton to radgrid header instead of default text header. Below is my code.

void radgrid1_PreRender(object sender, EventArgs e)
        {
            HiddenField hdfSortcolumn1 = (HiddenField)this.Page.FindControl("hdfSortColumn");
            RadGrid RadGrid1 = (RadGrid)Cache["radgrid1"];
            foreach (GridColumn col in RadGrid1.MasterTableView.RenderColumns)
            {
                foreach (GridHeaderItem headeritem in RadGrid1.MasterTableView.GetItems(GridItemType.Header))
                {
                    HtmlInputButton headerButton = new HtmlInputButton();
                    headerButton.Value = col.UniqueName;
                    Session["col"] = col.UniqueName;
                    string strColumn = col.UniqueName.Replace(" ", "%20");
                    string script = " document.getElementById('" + hdfSortcolumn1.ClientID + "').value = '" +
                                            strColumn + "'; RefreshSort('" +  Request.QueryString["ItemID"].ToString() + "');";
                    headerButton.Attributes["onclick"] = script;
                    headeritem[col.UniqueName].Controls.Add(headerButton);
                }
            }
        }
But duplicate header names are coming one is normal text and another one is dynamically added htmlbutton.
How to remove the default header text and only displaying htmlinputbutton.
Hope I can hear from you soon.
Thank you
