I have this linkbutton within a datalist and I'm trying to get access to the datalist on the pageload so i can set the linkbutton to be enabled or not based on the user's role.
<asp:DataList id="dlRecommendations" runat="server" DataKeyField="Key" Width="900">
<ItemTemplate>
<asp:LinkButton id="lnkEdit" Text="Edit" Runat="server" CommandName="Edit">
</asp:LinkButton>
</ItemTemplate>
</asp:DataList>
Within the page load I want to be able to access the linkbutton to enable or disable it based on the user's role.
private void Page_Load(object sender, System.EventArgs e) {
//perhaps something like this:
lnkEdit.Enabled = false;
....
}
I think you will be populating the datalist the first time page is loaded. So just wireup ItemDataBound, find link and disable it.
void dlRecommendations_ItemDataBound(object sender, DataListItemEventArgs e)
{
var link = e.Item.FindControl("lnkEdit") as LinkButton;
if (link != null)
{
link.Enabled = UserHasRight;//if user has right then enabled else disabled
}
}
DataList is a databound control - it builds rows only when data is supplied. To access link inside row use ItemDataBound event and access e.Item.FindControl("linkId");
