datagrid| sample
Often on the csdn to see a netizen asked how to achieve repeater,datalist, the datagrid nesting problem, the following gives a 3-layer nested example, can be nested indefinitely
<asp:repeater id= "Rpt_catalog" onitemdatabound= "Rpt_catalog_onitemdatabound" runat= "Server" >
<ITEMTEMPLATE> top floor repeater,index:<% #Container .dataitem%><br>
<asp:repeater id= "Rpt_board" onitemdatabound= "Rpt_board_onitemdatabound" runat= "Server" >
<ITEMTEMPLATE> 2nd Floor repeater,index:<% #Container .dataitem%><br>
<asp:repeater id= "Rpt_boardmaster" runat= "Server" >
<ITEMTEMPLATE> 3rd floor repeater,index:<% #Container .dataitem%><br>
</ITEMTEMPLATE>
</ASP:REPEATER>
</ITEMTEMPLATE>
</ASP:REPEATER>
</ITEMTEMPLATE>
</ASP:REPEATER>
Private Intfirst as Integer
Private Intsecond as Integer
Private Sub Page_Load (ByVal sender as System.Object, ByVal e as System.EventArgs) Handles MyBase.Load
' Put user code to initialize the page
Dim Al as New ArrayList
Al. ADD (0)
Al. ADD (1)
Rpt_catalog. DataSource = Al
Rpt_catalog. DataBind ()
End Sub
Sub Rpt_catalog_onitemdatabound (ByVal sender as Object, ByVal e as RepeaterItemEventArgs)
Dim rpt as Repeater
rpt = E.item.findcontrol ("Rpt_board")
Intfirst = E.item.itemindex
Dim Al as New ArrayList
Al. ADD (Intfirst & ". 0")
Al. ADD (Intfirst & ". 1")
Rpt. DataSource = Al
Rpt. DataBind ()
End Sub
Sub Rpt_board_onitemdatabound (ByVal sender as Object, ByVal e as RepeaterItemEventArgs)
Dim rpt as Repeater
rpt = E.item.findcontrol ("Rpt_boardmaster")
Intsecond = E.item.itemindex
Dim Al as New ArrayList
Al. ADD (Intfirst & "." & Intsecond & ". 0")
Al. ADD (Intfirst & "." & Intsecond & ". 1")
Rpt. DataSource = Al
Rpt. DataBind ()
End Sub
The code has been tested, but please optimize it yourself
