Only you can hide or show controls inside a grid In the rowDataBound or any grid event.

Try this code below:

    protected void gvOutput_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        try
        {

            if (e.Row.RowType == DataControlRowType.DataRow)
            {

            //get radio button value selected by user (default is all)
            if (rdAll.Checked)
                search.SearchType = rdAll.Value;
            else if (rdBelowTrigger.Checked)
                search.SearchType = rdBelowTrigger.Value;
            else if (rdAboveTrigger.Checked)
                search.SearchType = rdAboveTrigger.Value;
            else if (rdBelowSafety.Checked)
                search.SearchType = rdBelowSafety.Value;
            else if (rdBelowXWeeksWPO.Checked)
                search.SearchType = rdBelowXWeeksWPO.Value

              //Hide the Textbox
               TextBox txtQtyOrder10 = (TextBox)e.Row.FindControl("txtQtyOrder10");
               txtQtyOrder10.Visible = false;

            }
        }
        catch (Exception ex)
        {
            LoggingComponent.Instance.LogMessage(bo.Enums.LoggingType.Error, DateTime.Now, ex.Message, bo.Enums.Module.Order, "gvProductsAdded_RowDataBound", bo.Enums.ApplicationLevel.FrontEnd, "Error en los Productos a Despachar");
            DisplayMessage(GetGlobalResourceObject("Messages", "UnknowError").ToString(), bo.Enums.MessageType.Error);
        }


    }

I hope that help you.

Cheers
