    Commented line works for sorting rest column did not work. and in my application translation is also integrated. so i have to change the header text as per language. please suggest what should i do.

    Thanks In Advance.


    GridHeaderItem header = (GridHeaderItem)e.Item;
                //header["colFilename"].Text = dtfileSharingCofig.Rows[0]["fsNameSearch"].ToString();
                header["colUploadedBy"].Text = dtfileSharingCofig.Rows[0]["fsUploadedBySearch"].ToString();
                header["colFileType"].Text = dtfileSharingCofig.Rows[0]["fsFileTypeSearch"].ToString();
                header["colRating"].Text = dtfileSharingCofig.Rows[0]["fsRatingSearch"].ToString();
                header["colUploadedDate"].Text = "Uploaded Date";
                header["colRaters"].Text = "Raters";
                header["colViews"].Text = "Views";
                header["colFileSize"].Text = "File Size";

    Hi Muhammed,

    Assuming that sorting is enabled for RadGrid, then the header cells (TH elements) rendered will contain an anchor (A) tag that will sort the grid if clicked for example:
    <th scope="col" class="rgHeader">
        <a onclick="Telerik.Web.UI.Grid.Sort($find('RadGrid1_ctl00'), 'ShipName'); return false;" title="Click here to sort" href="javascript:__doPostBack('RadGrid1$ctl00$ctl02$ctl01$ctl03','')">ShipName</a>

    The following example will change the content of the header cell replacing everything in it with the newly defined text instead of changing the text of the anchor tag.
    header["ShipName"].Text = "New Name";

    Header cell renders as:
    <th scope="col" class="rgHeader">
        New Name

    Solution is to use the columns' HeaderText property to change the text, or, to get a reference to the anchor tag (LinkButton) in the code behind, and change the controls' text via its Text property.

    Below you can find two examples of changing the text:
    protected void RadGrid1_PreRender(object sender, EventArgs e)
        // Condition to logic only at initial load
        if (!IsPostBack)
            // Loop through all grid columns and change the text for all
            foreach (GridColumn col in RadGrid1.MasterTableView.RenderColumns)
                // change the HeaderText property of of the columns
                col.HeaderText = "New Text";
            // Change the text for an individual column
            GridColumn ShipNameColumn = RadGrid1.MasterTableView.GetColumn("ShipName") as GridColumn;
            ShipNameColumn.HeaderText = "Some other text";
            // refresh the grid
    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        if(e.Item is GridHeaderItem)
            GridHeaderItem headerItem = e.Item as GridHeaderItem;
            // Reference the link button
            LinkButton lButton = headerItem["ShipName"].Controls[0] as LinkButton;
            // change the button's text
            lButton.Text = "Link Button text";

    Kind regards,
