Generally, we require nested structure of grid to display hierarchical data or Master Child data. Here it is done using gridview nested in repeater.
In aspx Page:
<asp:Repeater ID="rpt" runat="server"
onitemdatabound="rpt_ItemDataBound">
<ItemTemplate>
<asp:GridView ID="Grd" runat="server">
</asp:GridView>
</ItemTemplate>
</asp:Repeater>
In .CS Page:
protected void Page_Load(object sender, EventArgs e)
{
rpt.DataSource = GetData();
rpt.DataBind();
}
protected void rpt_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
GridView gv = (GridView)e.Item.FindControl("grd");
if (gv != null)
{
DataRowView drv = (DataRowView)e.Item.DataItem;
gv.DataSource = GetSubData(Convert.ToInt32(drv["ID"]));
gv.DataBind();
}
}
}
private DataTable GetData()
{
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Name");
dt.Columns.Add("Size");
dt.Columns.Add("Enabled");
for (int i = 0; i < 3; i++)
{
for (int j = 0; j < 3; j++)
{
DataRow dr = dt.NewRow();
dr[0] = i.ToString();
dr[1] = i.ToString() + "-Name-" + j.ToString();
dr[2] = i.ToString() + "-Size-" + j.ToString();
dr[3] = Convert.ToBoolean(i % 2);
dt.Rows.Add(dr);
}
}
return dt;
}
protected DataTable GetSubData(int ij)
{
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("SubName");
dt.Columns.Add("SubSize");
dt.Columns.Add("Enabled");
for (int j = 0; j < 3; j++)
{
DataRow dr = dt.NewRow();
dr[0] = ij.ToString();
dr[1] = ij.ToString() + "-Name-" + j.ToString();
dr[2] = ij.ToString() + "-Size-" + j.ToString();
dr[3] = Convert.ToBoolean(ij % 2);
dt.Rows.Add(dr);
}
return dt;
}
Hope, It Helps.
