How do I programtically set a link and description column in grid viewer?

Question

User1324715958 posted

I have a grid viewer I'm trying to setup a link list on one side and a description on the other side. I put the fields in and pulled the data back. What did I do wrong here? Its populating one column with data and filling the data again, so its like its duplicating it.

Code:

 Private Sub BuildList()
        Try
            Dim dt As DataTable = DataFunctions.GetVisualBasicTutList

            gvVideoTutorials.DataSource = dt
            gvVideoTutorials.DataBind()
        Catch ex As Exception

        End Try
    End Sub

            gvVideoTutorials.DataSource = dt
            gvVideoTutorials.DataBind()
            gvVideoTutorials.AutoGenerateColumns = False

            gvVideoTutorials.Columns(0).ItemStyle = LinkButton
        Catch ex As Exception

Hi UOKSoftware,

You can use link button in template field of gridview and Eval function to bind value in linkbutton in aspx page. Try the following code snippets.

<div>
     <asp:GridView ID="GridView1" HeaderStyle-BackColor="#3AC0F2" HeaderStyle-ForeColor="White"
                runat="server" AutoGenerateColumns="false">
           <Columns>                    
              <asp:TemplateField HeaderText="URL">
                   <ItemTemplate>
                        <asp:LinkButton Text='<%# Eval("URL") %>' ID="lnkView" runat="server" />
                   </ItemTemplate>
             </asp:TemplateField>
             <asp:BoundField DataField="Description" ItemStyle-CssClass="Description" HeaderText="Description"
                        ItemStyle-Width="150" />
          </Columns>
     </asp:GridView>
</div>


protected void Page_Load(object sender, EventArgs e)
{
      if (!IsPostBack)
       {
             DataTable dt = new DataTable();
             dt.Columns.AddRange(new DataColumn[2] { new DataColumn("URL",typeof(string)),
                        new DataColumn("Description",typeof(string)) });

             dt.Rows.Add("forums.asp.net", "TestA");
             dt.Rows.Add("forums.asp.net", "TestB");
             dt.Rows.Add("forums.asp.net", "TestC");
             dt.Rows.Add("forums.asp.net", "TestD");
             GridView1.DataSource = dt;
             GridView1.DataBind();
        }
}

Best Regards,
