Parent Grid row bound Event:

C#

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string DepartmentID = gvDepartment.DataKeys[e.Row.RowIndex].Value.ToString();
GridView gvCompleated = e.Row.FindControl("gvCompleated") as GridView;
GridView gvRunning = e.Row.FindControl("gvRunning") as GridView;
TaskGateway employeeGateObj = new TaskGateway();
gvRunning.DataSource = employeeGateObj.GetTaskTable(DepartmentID);
gvRunning.DataBind();
gvCompleated.DataSource = employeeGateObj.GetPendingTaskTable(DepartmentID);
gvCompleated.DataBind();
foreach (GridViewRow gr in gvCompleated.Rows)
{
if (gr.RowType == DataControlRowType.DataRow)
{
LinkButton lnkbtnresult = (LinkButton)gr.Cells[0].FindControl("requestID3");
if (lnkbtnresult != null)
{
lnkbtnresult.Click += new System.EventHandler(requestID3_Click);
}
}

}
foreach (GridViewRow gr in gvRunning.Rows)
{
if (gr.RowType == DataControlRowType.DataRow)
{
LinkButton lnkbtnresult = (LinkButton)gr.Cells[0].FindControl("requestID3");
if (lnkbtnresult != null)
{
lnkbtnresult.Click += new System.EventHandler(requestID3_Click);
}
}
}
}

If you want to get the click event of link button then there is simple code, user RowCommad event of grid view:
see:
Assume gridview is like

<asp:gridview id="grvTest" runat="server" xmlns:asp="#unknown">
  <asp:templatefield>
    <itemtemplate>
      <asp:linkbutton id="lnk" runat="server" text="Test" commandname="TestCommand" />
    </itemtemplate>
  </asp:templatefield>
</asp:gridview>

and your aspx.cs file contense the event RowCommad like :

Protected Void grvTest_RowCommand(object sender, GridViewCommandEventArgs e) 
{
    If(e.CommandName == "TestCommand")
    {
      ///Do your code here
    }
}

if helpful to you, accept the solution
