  How to handle more than one commandfields in gridview

  Apr 23, 2012 11:06 AM|LINK

  Hi,
    How to handle multiple commandfields in gridview.

  My aspx code is:

  <pre type="c#">

  &lt;asp:GridView ID="GridOracle" runat="server" AllowSorting="True" AutoGenerateColumns="False"
                          DataKeyNames="DIS_CHAPTER_ID" OnSelectedIndexChanged="GridOracle_SelectedIndexChanged"
                          BackColor="#CCCCCC" BorderColor="#CCCCCC" BorderStyle="Solid" BorderWidth="3px"
                          CellPadding="4" CellSpacing="2" ForeColor="Black"&gt;
                          &lt;%-- BorderColor=#999999--%&gt;
                          &lt;Columns&gt;
                              &lt;asp:BoundField DataField="SEC_NAME" HeaderText="Section Name" ReadOnly="True" ItemStyle-HorizontalAlign="Left"
                                  ItemStyle-Font-Bold="true" ItemStyle-VerticalAlign="Middle"&gt;
                                  &lt;ItemStyle HorizontalAlign="Left" VerticalAlign="Middle" Font-Bold="True"&gt;&lt;/ItemStyle&gt;
                              &lt;/asp:BoundField&gt;
                              &lt;asp:BoundField DataField="CHAPTER_NAME" HeaderText="CourseName" ReadOnly="True"
                                  ItemStyle-HorizontalAlign="Left" ItemStyle-VerticalAlign="Middle"&gt;
                                  &lt;ItemStyle HorizontalAlign="Left" VerticalAlign="Middle"&gt;&lt;/ItemStyle&gt;
                              &lt;/asp:BoundField&gt;
                              &lt;asp:BoundField DataField="Duration" HeaderText="Duration" ItemStyle-HorizontalAlign="Left"
                                  ItemStyle-VerticalAlign="Middle"&gt;
                                  &lt;ItemStyle HorizontalAlign="Left" VerticalAlign="Middle"&gt;&lt;/ItemStyle&gt;
                              &lt;/asp:BoundField&gt;
                              &lt;asp:CommandField CausesValidation="False" InsertVisible="False" ShowCancelButton="False"
                                  ButtonType="Image" ShowSelectButton="True" HeaderText="Material" ItemStyle-HorizontalAlign="Center"
                                  ItemStyle-VerticalAlign="Middle" SelectImageUrl="~/Content/Images/PDFLogo.png"&gt;
                                  &lt;ItemStyle HorizontalAlign="Center" VerticalAlign="Middle"&gt;&lt;/ItemStyle&gt;
                              &lt;/asp:CommandField&gt;
                              &lt;asp:CommandField  CausesValidation="False" InsertVisible="False" ShowCancelButton="False"
                                  ButtonType="Image" ShowSelectButton="True" HeaderText="Material1" ItemStyle-HorizontalAlign="Center"
                                  ItemStyle-VerticalAlign="Middle" SelectImageUrl="~/Content/Images/PDFLogo.png"&gt;
                                  &lt;ItemStyle HorizontalAlign="Center" VerticalAlign="Middle"&gt;&lt;/ItemStyle&gt;
                              &lt;/asp:CommandField&gt;
                            &lt;/Columns&gt;
                          &lt;FooterStyle BackColor="#CCCCCC" /&gt;
                          &lt;HeaderStyle BackColor="#CCCCCC" Font-Bold="True" ForeColor="Black" /&gt;
                          &lt;PagerStyle BackColor="#CCCCCC" ForeColor="Black" HorizontalAlign="Left" /&gt;
                          &lt;RowStyle BackColor="White" /&gt;
                          &lt;SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" /&gt;
                          &lt;SortedAscendingCellStyle BackColor="#F1F1F1" /&gt;
                          &lt;SortedAscendingHeaderStyle BackColor="#808080" /&gt;
                          &lt;SortedDescendingCellStyle BackColor="#CAC9C9" /&gt;
                          &lt;SortedDescendingHeaderStyle BackColor="#383838" /&gt;
                      &lt;/asp:GridView&gt;

  </pre>

  My aspx.cs code for commandfield

  <pre type="html">
  protected void GridOracle_SelectedIndexChanged(object sender, EventArgs e)
          {
              try
              {
                  if (GridOracle.SelectedIndex &gt; -1)
                  {
                          this.Id = Convert.ToInt32(GridOracle.DataKeys[GridOracle.SelectedIndex].Value);
                          string _FName = "select FILE_NAME from OM_DOC_ALL where DIS_CHAPTER_ID = " + Id;
                          string _FileName = (string)SqlHelper.ExecuteScalar(strConn, CommandType.Text, _FName);
                          string FileName = "~/Downloads/OracleMaterial/" + _FileName + ".pdf";
                          Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName);
                          WebClient client = new WebClient();
                          string pdfPath = Server.MapPath("../Downloads/OracleMaterial/" + _FileName + ".pdf");
                          Byte[] buffer = client.DownloadData(pdfPath);
                          BinaryWriter bw = new BinaryWriter(Response.OutputStream);
                          bw.Write(buffer);
                          bw.Close();
                          Response.ContentType = "application/pdf";
                          Response.Flush();
                          Response.Close();
                     
                  }
                  else
                  {
                      //Clear Controls
                  }
              }
              catch (Exception ex)
              {
                  ErrorHandling.ErrorLog("PageLoad: ExploreJobs.aspx.cs ,  Error : " + ex.Message);
              }
         
         
      }
  </pre>

  hi, i will suggest you to use ButtonField instead of CommandField

  <asp:ButtonField HeaderText="Material" CommandName="Material" Text="Select" />
  			<asp:ButtonField HeaderText="Material1" CommandName="Material1" Text="Select" />
  
  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
  	{
  		int index = ((e.CommandSource as Button).NamingContainer as GridViewRow).RowIndex;
  		switch (e.CommandName)
  		{
  			case "Material":
  				Response.Write("Material");
  				break;
  			case "Material1":
  				Response.Write("Material1");
  				break;
  		}
  	}

  Refer :http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.rowcommand.aspx

  hi, you can get id like below

           

  <asp:ButtonField HeaderText="Material" CommandName="Material" Text="Select" />
      <asp:ButtonField HeaderText="Material1" CommandName="Material1" Text="Select" />
   
  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
          {
                 int index = ((e.CommandSource as Button).NamingContainer as GridViewRow).RowIndex;                int Id = Convert.ToInt32(GridOracle.DataKeys[index].Value);                 switch (e.CommandName)
                  {
                          case "Material":
                                  Response.Write("Material");
                                  break;
                          case "Material1":
                                  Response.Write("Material1");
                                  break;
                  }
          }
