dynamically add a link button in gridview template field at run time together a label control

Question

I have a gridview in my form. I am working with RowDataBound event to the grid. Now I have a template field inside columns of the gridview. A label has been taken inside template field. I want to add a link to this label on RowDataBound event at runtime, but .System.Web.UI.WebControls.LinkButton is showing instead of link button. How do I add a link button with label text in the grid view?

Just add a linkbutton inside your templatefield

<asp:GridView runat="server" ID="gridView">
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:LinkButton runat="server" ID="lnkTest"></asp:LinkButton>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

Then in your rowdatabound event you can find it and do whatever you want

void gridView_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            Entity entity = e.Row.DataItem as Entity;

            LinkButton lnkTest = e.Row.FindControl("lnkTest") as LinkButton;
            lnkTest.CommandArgument = entity.ID.ToString();
            lnkTest.Text = entity.Name;
        }
    }

You can then subscribe to gridview Command event and correct CommandArgument will be passed when clicking by linkbutton. Hope this helps.
