Nasted GridView using Entity DataModel

Page View:-

Under showdata button_click

protected void Button1_Click(object sender, EventArgs e)

{

try

{

Utility obj = new Utility();

GridView1.DataSource = obj.Getrest();

GridView1.DataBind();

for (int i = 0; i < GridView1.Rows.Count; i++)

{

GridView gv = (GridView)GridView1.Rows[i].FindControl("GridView2");

Label bv = (Label)GridView1.Rows[i].FindControl("lbl");

gridviewModel.menu obj1=new gridviewModel.menu ();

gv.DataSource = obj.Getmenu(bv.Text);

gv.DataBind();

}

Add ADO.NET Entity Data Model under App_code and select database tables

add new class Utility.cs and write code under utility class

Under Utility Class:-

public List<gridviewModel.rest> Getrest()

{

gridviewModel.gridviewEntities obj = new gridviewModel.gridviewEntities();

var x = from n in obj.rests select n;

return x.ToList<gridviewModel.rest>();

}

public List<gridviewModel.menu> Getmenu(object ss)

{

int s = int.Parse(ss.ToString());

gridviewModel.gridviewEntities obj = new gridviewModel.gridviewEntities();

var c=from n in obj.menus where n.Rid==s select n;

return c.ToList<gridviewModel.menu>();

}
