Hello,
I have a *.aspx page where I allow users to search a database table via  stored procedure.
When the user clicks an asp.button called "find", it fires the stored procedure which populates a gridview control.  

I am attempting to hide two columns on this gridview and cannot seem to accomplish that.

My *.aspx code follows:
---------------
 <asp:SqlDataSource ID="ds_warrantsearchresults" runat="server" ConnectionString="<%$ ConnectionStrings:Jailinfo_JAUConnectionString1 %>"
            SelectCommand="sp_getAllWarrantsbyName" SelectCommandType="StoredProcedure">
            <SelectParameters>
                <asp:ControlParameter ControlID="FirstNameTextBox" Name="Firstname" PropertyName="Text"
                    Type="String" Size="50" ConvertEmptyStringToNull="false" />
                <asp:ControlParameter ControlID="LastNameTextBox" Name="Lastname" PropertyName="Text"
                    Type="String" ConvertEmptyStringToNull="false" />
                <asp:ControlParameter ControlID="SpnTextBox" Name="Spn" PropertyName="Text" Type="String"
                    ConvertEmptyStringToNull="false" />
                 <asp:ControlParameter ControlID="DobTextBox" Name="Dob" PropertyName="Text" Type="String"
                    ConvertEmptyStringToNull="false" />    
            </SelectParameters>
        </asp:SqlDataSource>
     
               
        <asp:GridView ID="gv_warrantsearchresults" runat="server" DataKeyNames="Spn" AllowSorting="True"
            DataSourceID="ds_warrantsearchresults" CellPadding="4" Font-Names="Arial" Font-Size="Small"
            ForeColor="#0033CC" GridLines="None" Width="580px" EmptyDataText="NO Matching Data Found"
            OnSelectedIndexChanged="gv_warrantsearchresults_SelectedIndexChanged" PageSize="15"
            ShowFooter="True" AllowPaging="true">
            <%-- <HeaderStyle CssClass="GridHeader" /> --%>
            <RowStyle BackColor="#EFF3FB" />
            <EmptyDataRowStyle Font-Names="Arial" Font-Size="Small" ForeColor="Red" />
            <Columns>
                <asp:CommandField ShowSelectButton="True" />
            </Columns>
            <FooterStyle BackColor="White" Font-Bold="True" ForeColor="White" Font-Names="Arial"
                Font-Size="X-Small" />
            <PagerSettings Mode="NumericFirstLast" />
            <PagerStyle BackColor="#507CD1" ForeColor="#507CD1" HorizontalAlign="center" />
            <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
            <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" HorizontalAlign="Left" />
            <EditRowStyle BackColor="#2461BF" />
            <AlternatingRowStyle BackColor="White" HorizontalAlign="Left" VerticalAlign="Top" />
        </asp:GridView>

-----------

The codebehind of the asp.button that fires the stored procedure follows:
-----------

protected void Button1_Click(object sender, EventArgs e)
        {
            pnl_gvWarrantSearchResults.Visible = true;
            //gv_warrantsearchresults.Visible = true;

            gv_warrantsearchresults.Columns[0].Visible = true;
            gv_warrantsearchresults.Columns[1].Visible = true;
            //gv_warrantsearchresults.Columns[2].Visible = true;
            //gv_warrantsearchresults.Columns[3].Visible = true;
            //gv_warrantsearchresults.Columns[4].Visible = false;
           
            pnl_gvSearchResults_Detailsview.Visible = true;
            dv_searchresults.Visible = true;

            pnl_wsdetail_imageview.Visible = true;

            //pnl_agreetoterms.Visible = true;
            //txt_AgreedToTerms.Text = "You Hereby Agree to Terms & Conditions";

            pnl_display_ddl.Visible = true;


        }

---------------

ANY HELP with this would be greatly appreciated.

Here is sample code:-
foreach (GridViewRow gvr in GridView1.Rows)
	    {
//add aditional logic here
	        gvr.Cells[0].Visible = false;    
            }

I used this once and it worked :

  protected void grid1_RowDataBound(object sender, GridViewRowEventArgs e)
  {

    if  ( condition)
    {
      e.Row.Cells[1].Visible = false;
      e.Row.Cells[2].Visible = false;
      e.Row.Cells[3].Visible = false;

   ..

Use the gridview's rowdatabound event and change the  "visible" property to false:

      e.row.cells(0).visible = false;

Or change the display attribute to "none":

      e.row.cells(0).style.add("display", "none");

You can hide the columns with the code you have.  You just need to make sure they are hidden prior to the databinding.

gv_warrantsearchresults.Columns[0].Visible = false;
gv_warrantsearchresults.Columns[1].Visible = false;

Open in new window


You may want to create a private property on the page that tracks if the columns should be hidden or not and then look at that value on page_load to see if the columns should be hidden.

void CustomersGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
  {

    if(e.Row.RowType == DataControlRowType.DataRow)
    {
      // Display the company name in italics.
      e.Row.Cells[index].Visible = false;

    }

  }
