Hello,
I saw the same questions on this forum but they have had not replies so I'm asking the question again.
This is what I get when try to run app with grid:
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
I set DataSource property from codebehind and data source is a simple dataset.
Any ideas? I use v10.3
Thank you.
I am getting this same error. This is my markup and im binding to a anonymous type, but it shouldn't matter.
<div align="center" style="width: 100%" > <table> <ig:WebGroupBox ID="wgbPayOnInvoice" runat="server" Text="Pay On Invoice" Width="98%"> <Template> <ig:WebDataGrid ID="wdgPayOnInvoice" DataKeyFields="IKey" runat="server" AutoGenerateColumns="true" Height="350px" Width="100%"> <Columns> <ig:BoundDataField Key="IKey" DataFieldName="IKey" Hidden="true" /> <ig:BoundDataField Key="BillNumber" DataFieldName="BillNumber"> <Header Text="Bill Number" /> </ig:BoundDataField> <ig:BoundDataField Key="LabCode" DataFieldName="LabCode"> <Header Text="Lab" /> </ig:BoundDataField> <ig:BoundDataField Key="InvoiceNumber" DataFieldName="InvoiceNumber"> <Header Text="Invoice Number" /> </ig:BoundDataField> <ig:BoundDataField Key="TransactionAmount" DataFieldName="TransactionAmount" DataFormatString="{0:C0}"> <Header Text="Total" /> </ig:BoundDataField> <ig:BoundDataField Key="Balance" DataFieldName="Balance" DataFormatString="{0:C0}"> <Header Text="Balance" /> </ig:BoundDataField> </Columns> </ig:WebDataGrid> </Template> </ig:WebGroupBox> </table> </div>
This is the full error.

Anyone have any ideas?
I found the issue with my webdatagrid. I removed this from my markup and it worked. Not sure why this is causing a issue.
<ig:BoundDataField Key="IKey" DataFieldName="IKey" Hidden="true" />
Hope this helps.
HI dprosko,
What are you doing to the grid in the code-behind? Do you have template columns? Or do you have server side code in JS?

I do NOTHING at all. Here is my markup and code-behind:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ZSheetPage.ascx.cs"
Inherits="UpeWeb.ASPNET.Pages.ZSheetPage" %>
<%@ Register Assembly="Infragistics4.Web.v10.3, Version=10.3.20103.1013, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb"

Namespace="Infragistics.Web.UI.NavigationControls" TagPrefix="ig" %>
<%@ Register src="../Controls/FilterListDialogButton.ascx" tagname="FilterListDialogButton" tagprefix="uc1" %>
<script type="text/javascript">
function menuItemClick(sender, args) {
if (args.getItem().get_key() == "btnMacros" || args.getItem().get_key() == "btnFilterListDialog")
args.set_cancel(true);
}
</script>
<asp:UpdatePanel ID="ZSheetPanel" runat="server">

<div id="zsheetContainer" runat="server">

</div>
</ContentTemplate>
</asp:UpdatePanel>
protected void Page_Load(object sender, EventArgs e)
{
if (_zsheet != null)
LoadMacroList();
ZSheetGrid.DataSource = _zsheet.ZSInfo.data; // data is of type List<>
Hello.
Would you please do something? I just installed 11.1 and the same error occures. Is there anything in "not documented" features or whatever? I stuck with this and cannot move on.
HI,
I don't see anything obviously wrong with your sample code you've pasted. My suggestion is to contact Developer Support so they can walk through your sample with you and attempt to figure out what is going on.
regards,David Young
I just tried all this with WebDataGrid and it runs fine. Problem starts when I try to use WebHierarchicalDatagrid
Hi,
Thank you for reply.
Now I'm using 2011.1 so problem perhaps somewhere in your code.
As I said previously, your code looked ok to me. Have you tried upgrading to the latest Service Release for 10.3 to see if the issue is resolved there. Or contact Developer Support so they can walk through your sample and attempt to locate the problem.
thanks,Dave
Do you have any news about this problem?
I got the same error in WebDataGrid. Problem starts when I set Hidden property to true on some columns which contain GUIDs. When all columns are visible, everything is ok. Any ideas?
