Gridview call another gridview..

Question

See more:

I would like to show another GridView when I click any row of first GridView.
I have problem to find out index of particular row at selected index event of first GridView.

In the first GridView I have client names and in the second GridView I have project name according to the client.
Like client1 has 2 projects and client2 has 5 projects.

I would like when I click on first row of first GridView, meaning click on client1 2 projects show in the second GridView.
I am Working in ASP.NET Web Application.

Thanks..
Here is the code:

C#

protected void grdClient_SelectedIndexChanged(object sender, EventArgs e)
      {
          Project ObjProject = new Project();
          int userClientID;
          userClientID = Convert.ToInt32(((Label)(grdClient.FindControl("lbUserClientID"))).Text);// Object reference not set to an instance of an object.
          ObjProject.UserClientID = userClientID;

          grdProject.DataSource = ObjProject.GetProjectList();
          grdProject.DataBind();
      }

I am unable to typecast label value at SelectedIndex event.

What is supposed to mean: "call a gridview"? It's now a function, method or procedure, not a property.

GridViewRow row = ItemsGridView.SelectedRow


Project ObjProject = new Project();
            int userClientID;
            userClientID = Convert.ToInt32(((Label)(row.Cells[0].FindControl("lbUserClientID"))).Text);// Object reference not set to an instance of an object.
            ObjProject.UserClientID = userClientID;
 
            grdProject.DataSource = ObjProject.GetProjectList();
            grdProject.DataBind();

Why don't you use SelectedValue property?
If your gridView has DataKeyNames property set you don't have to use such long way to retrieve desired value.

C#

protected void grdClient_SelectedIndexChanged(object sender, EventArgs e)
{
    if(grdClient.SelectedValue != null)
    {
       Project ObjProject = new Project();
       int userClientID;
       userClientID = int.Parse(grdClient.SelectedValue.ToString());
       ObjProject.UserClientID = userClientID;

      grdProject.DataSource = ObjProject.GetProjectList();
      grdProject.DataBind();
    }
}

Gridview call another gridview..
