  i am getting nothing , i am trying to retrieve checkbox value and email address from gridview via code, I am succeeded in getting Checkbox value successfully but cannt get email address, even grid view has it, but i cant get, just blank, here is the code:

  .cs :

  protected void GridViewAdminViewEmplys_RowCommand(Object sender, GridViewCommandEventArgs e)
      {
          if (e.CommandName == "Update")
          {
              //Response.Write("Updated");
              GridView gvr = GridViewAdminViewEmplys;
              int index = Convert.ToInt32(e.CommandArgument);
              int pk = Convert.ToInt32(GridViewAdminViewEmplys.DataKeys[index].Value);
              Response.Write(pk);
  
              bool isChecked = (gvr.Rows[index].Cells[8].Controls[0] as CheckBox).Checked;
              //CheckBox chk = (CheckBox)gvr.Rows[index].FindControl("chkBoxStatus");
             // Response.Write(isChecked);
              if (isChecked == true)
              {
                  String email = gvr.Rows[index].Cells[3].Text;
                  Response.Write(email);
                  Response.Write("TRUE CONDITION");
  
              }
              else
              {
                  Response.Write("False condition");
              }

  .aspx:

  <asp:GridView ID="GridViewAdminViewEmplys" runat="server" AllowPaging="True"
           AutoGenerateColumns="False" DataKeyNames="userid"

  String email = gvr.Rows[index].Cells[3].Text;

  Replace the above line like this...

  String email = gvr.Cells[3].Text;

  You need not use Rows[index] as you already have gridview row...

  Also try to get gridviewrow like this...

  GridViewRow gvr =GridViewAdminViewEmplys.Rows[indRow];

  I believe, since, you're in edit mode the text will be in a TextBox.  Try:

  string email = (gvr.Rows[index].Cells[3].Controls[0] as TextBox).Text;

  Add LinkButton to ItemTemplate and bind CommandArgument property to row index:

  <asp:TemplateField HeaderText="Vendor Name">
             <ItemTemplate>
                <asp:LinkButton ID="lnkvendorname" runat="server" CommandArgument='<%#Eval("userid")%>'
                              CommandName="Update" Text="Get"></asp:LinkButton>
             </ItemTemplate>
  </asp:TemplateField>

  view the page and click the link button, please give a try
