I am trying to place a datalist inside datalist. I managed to place a datalist inside gridview but not datalist inside datalist.
Below is the code I am using to bind the datalist into the master gridview, I am trying to change this code in such way it will be right for datalist inside datalist but so far I did not succeed.

I generate dynamically an usercontrol, the user write the quantity, 3 or 4 or 5, press generate and get N controls to fill with cars parts.I need get the values inside any textboxes but the method find never found the controls...I am using this code to generate dynamically my controls:
[Code]....
when the controls is loaded into the WizardStep, I need to find it to get the values inserted by the user in the textboxes.
[Code]....
but I never find the control always is null, I place it inside a Panel called UnidadesPanel.
After I add a new author I am displaying the author inside the gridview in an Accordian and I need to expand the accordian for this one record, in the btn_AddAuthor event I am trying this:
[Code]....
the problem that I am having is that nothing happens: , the accordian is not expanded but I need it to be expanded.
I have a label control inside of repeater and I can't seem to get FindControl to locate the label inside of the repeater or even the repeater itself. I'm not sure what I'm doing wrong here. OnItemDataBound is firing because "hello1" is being written but if I put anything inside of the For Next loop of rptMarketFundamentals, nothing is run inside of it.
<asp:Repeater id="rptMarketFundmentals" runat="server" DataSourceID="dsMarketFundamentals" OnItemDataBound="rptMarketFundamentals_ItemDataBound"> <asp:Label ID="lblOwnershipCategory" runat="server" Text='<%# Eval("OwnershipCategory") %>' /> </asp:Repeater> Sub rptMarketFundamentals_ItemDataBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs) Response.Write("hello1") 'this works Dim dataItem As RepeaterItem For Each dataItem In rptMarketFundmentals.Items Response.Write("hello2") 'this does not work Dim lblOwnershipCategory As Label = CType(dataItem.FindControl("lblOwnershipCategory"), Label) If lblOwnershipCategory.Text.ToLower = "family firm" Then blOwnershipCategory.CssClass = "highlight" End If Next End Sub
I have a situation where I need to dynamically disable certain controls. I will not be knowing the type of control. I tried to use FindControl(""), but this does not have the "Enabled" property, it only has "Visible" property.
