We are using WebHierarchicalDataGrid (Version -13.1.20131.2069)
When i am deleting the 2 rows continuously i am not received any issues when i am deleting the next row continuously (3rd) i have received the following issue.
Here i have mentioned code snippets.
<script type="text/javascript" id="igClientScript1"> // Redirect to location page. function whdgVendor_ContainerGrid_DoubleClick(sender, eventArgs) { if (sender._level != 0) { return false; } else { var row = eventArgs.get_item().get_row().get_dataKey()[0]; __doPostBack('btnRedirect', row); } } // Confirmation dialog for deleting the branch. function ConfirmDeletion(sender, eventArgs) { // Open a dialog to use asking for a yes/no about deletion var continueDelete = confirm("Are you sure you want to delete this record?"); // if end-user says no, cancel the delete action if (!continueDelete) eventArgs.set_cancel(true); } </script>

Thanks & Regards,

Set EnableViewState="false" on each control inside each template field; e.g.
<ig:WebHierarchicalDataGrid runat="server" ID="hdg" DataSourceID="hds" DataKeyFields="ID" OnInitializeRow="hdg_InitializeRow"> <Columns> <ig:TemplateDataField Key="ID" Text="Relationship ID"> <ItemTemplate> <asp:Label runat="server" ID="lblID" EnableViewState="false" /> </ItemTemplate> </ig:TemplateDataField> <ig:TemplateDataField Key="Add"> <ItemTemplate> <asp:Button runat="server" ID="btn" Text="Add" CommandName="Add" EnableViewState="false" /> </ItemTemplate> </ig:TemplateDataField>
</Columns>

Hi,
If you still need assistance with the matter, please let me know.
Hello Narayanan Pandaram,
Thank you for posting in our forum.
Your markup seems to be correct and I am unable to tell what is causing this exception from the provided details. I would need a small isolated sample reproducing the issue so I can investigate it further. Thank you.
