Example of nested repeater in repeater

The code is as follows:

protected void Page_Load (object sender, EventArgs e)

{

if (! Page.IsPostBack)

{

This.dtcategory = Getcategorytable ();

This.dtproduct = Getproducttable ();

Rptcategorylist.datasource = dtcategory;

Rptcategorylist.databind ();

}

}

Prepare a list of categories

DataTable getcategorytable ()

{

DataTable dt = new DataTable ();

Dt. Columns.Add ("CategoryID", typeof (int));

Dt. Columns.Add ("Categorytitle", typeof (String));

for (int i = 1; I <= 3; i++)

{

DataRow row = dt. NewRow ();

Row["CategoryID"] = i;

row["Categorytitle"] = "Classification name" + i + "";

Dt. Rows.Add (row);

}

return DT;

}

Prepare a list of products

DataTable getproducttable ()

{

DataTable dt = new DataTable ();

Dt. Columns.Add ("ProductTitle", typeof (String));

Dt. Columns.Add ("CategoryID", typeof (int));

for (int i = 1; I <= 9; i++)

{

DataRow row = dt. NewRow ();

row["ProductTitle"] = "Product Name" + i + "";

if (i > 6) row["CategoryID"] = 3;

else if (i > 3) row["CategoryID"] = 2;

else row["CategoryID"] = 1;

Dt. Rows.Add (row);

}

return DT;

}

Get a product of a category

DataTable getproducttable (int CategoryID)

{

DataView dv = This.dtProduct.DefaultView;

Dv. RowFilter = "Categoryid=" + CategoryID + "";

Return DV. ToTable ();

}

protected void Rptcategorylist_itemdatabound (object sender, RepeaterItemEventArgs e)

{

if (E.item.itemtype = = ListItemType.AlternatingItem | | e.item.itemtype = = listitemtype.item)

{

DataRowView DRV = (DataRowView) e.Item.DataItem;

Literal Ltltitle = (Literal) e.item.findcontrol ("Ltltitle");

Ltltitle.text = drv["Categorytitle"]. ToString ();

Repeater rptproductlist = (Repeater) e.item.findcontrol ("Rptproductlist");

Rptproductlist.datasource = getproducttable (Convert.ToInt32 (drv["CategoryID"));

Rptproductlist.databind ();

}

}

protected void Rptproductlist_itemdatabound (object sender, RepeaterItemEventArgs e)

{

if (E.item.itemtype = = ListItemType.AlternatingItem | | e.item.itemtype = = listitemtype.item)

{

DataRowView DRV = (DataRowView) e.Item.DataItem;

Literal Ltltitle = (Literal) e.item.findcontrol ("Ltltitle");

Ltltitle.text = drv["ProductTitle"]. ToString ();

}

}
