Hi,

I have a nested datagrid which has drop down lists inside it. Which are populated as follows...
Private Sub loadSystemsTables(ByRef dg As DataGrid)
'loads the dropdownlists for the editors
Dim db As New database
Dim SystemDS As DataSet
Dim evtHandle As New DataGridItemEventHandler(AddressOf childItemDataBound)
Dim SystemsSQL As String
If Not dg Is Nothing Then
'we have a DataGrid
SystemsSQL = "SELECT * FROM tblSystems"

SystemDS = db.db_getDataSet(SystemsSQL)

AddHandler dg.ItemDataBound, evtHandle

dg.DataSource = SystemDS
dg.DataBind()

Else
MessageLabel.Text = "Couldnt find DataGrid"
MessageLabel.UpdateAfterCallBack = True
End If
End Sub

Public Sub childItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs)

'Dim sysID as integer
'Dim lbl As Label
'lbl = e.Item.FindControl("SystemsIDLabel")
'If Not lbl Is Nothing Then
' sysID = lbl.Text
'End If

Dim ddl As Anthem.DropDownList
ddl = e.Item.FindControl("RoleDropDown")
If Not ddl Is Nothing Then
loadRoleEditors(sysID, ddl)
End If

End Sub

Inside the inner datagrid I have the following items...

<anthem:label runat="server" id="SystemIDLabel"><![CDATA[<%#Container.DataItem("SystemID")%>]]>
<anthem:dropdownlist runat="server" id="RoleDropDown" cssclass="DDLSize5">

What I need to know is how to get the value of the "SystemIDLabel" label so I can pass it to the loadRoleEditors sub as I need to set the drop down lists to previously selected values. The value is displayed when the code is run, but if I uncomment the section in sub childItemDataBound() then I get Null. What I think is happening is the sub is running before the value is inserted into the datagrid.

Anyone know how to get this, or is there another way.
Cheers
Andy

The Browser Toolbar.

You can not avoid back buttons. You can work around it by having a history.forward() snippet and page cache expiries.

I've set the page no-cache on page load and it's working fine in Internet Explorer but not running fine in mozilla as i've described below please have a bit of your precious time....

1.) I've a folder named Admin in this folder i've around ten web forms which can only be accessed by the administrator the first web form(after the successful login id and password) there are some more links on this web form e.g Top(one of the link) as i click on this Top link another web form opens and now if i click on the Log Out button then it opens the first web form Top if i use Back Button

plz suggest what should i do......

2.) I have a link for Change Password if the admin wants to change his/her password he/she can do this link show a Div on the form once the admin change his password and then click on the LogOut button and then use the back button then it show the Div again but it must not show it because the page is not being cached

This is my code to no-cache
Response.Buffer = true;
Response.ExpiresAbsolute=DateTime.Now.AddDays(-1d);
Response.Expires =-1500;
Response.CacheControl = "no-cache";

Please have a bit of your precious time ...........

Response.Redirect("../Admin/HomePage.aspx");

and in Page Load i check whether or not Session["UserName"] is empty it is then redirect to home page otherwise the user to visit the information..........

But still it's not working in best of it's way...........

the browser back button will take you back to the page you were just on without going back to the server and re-loading the page, therefore the onload will not run again until the page is refreshed.
The only way i can think is to somehow delete the cache or apply some sort of method to run when the browser back button runs
