Hi,
I'am trying to add a new row to the child grid and I get "Element cannot be undefined" exception.
1. WebHierarchicalDataGrid has 2 levels of data.
2. BatchUpdating is on. (it's important, if it is off - works fine)
3. AddingRow behaviour has been added.
4. I enter some values for a new row and press 'Enter' after that the error appears
Please check is it a real bug or I do something wrong.
Thanks,
Alexander
Hi Alexander,
Obviously, your example sounds very simple. But some key points include what browser you are seeing this in, what level you're adding the row in, what your grid actually looks like (the columns), and what version you're running. If you don't have the latest Service Release, I would suggest downloading it. I tried with the latest 11.2 and got no exception in either the parent or child band.If you're able to attach a sample here, that would be great.

Hi, David!
Thank you.
I've download the lates Service Release, and the problem has come away.
Could you help me with following task:
I want to use UserControl as RowEditingTemplate.
All works fine, the control is shown correctly but there is a problem with data binding, I've done it as shown below, but I don't like it, maybe you could suggest something better:
<ig:RowEditingTemplate > <ClientBindings> <ig:RowEditingClientBinding ColumnKey="SubRuleId" ControlID="subRuleTemplate" GetValueJavaScript="$get({ClientID}+'_txtSubRuleId'). SetValueJavaScript="$get({ClientID}+'_txtSubRuleId').value = {value};" /></ClientBindings><Template> <controls:SubRuleTempate runat="server" ID="subRuleTemplate"></controls:SubRuleTempate> </Template></ig:RowEditingTemplate>
SubRuleTemplate - it is UserControl. it has asp:TextBox with id = txtSubRuleId
I dont like the way I am getting to the edit controls located on UserControl:
$get({ClientID}+'_txtSubRuleId')
The second problem that I can set ControlID = subRuleTemplate only for one RowEditingClientBinding,otherwise I get error:
An EditRowClientBinding linked to the template control with the ControlID = subruleTemplate has already been found. Each column only supports a single binding object to a single editor.

If I set controlID = txtSubRuleId, the substitution {ClientID} is null. (as for SetValueJavaScript, as for GetValueJavaScript)
I am sure it is because control txtSubRuleId cannot be found on the server side if it is located in the UserControl.
Am I right that it is uncommon scenario to use UserControl as template?
It is very convenient because it reduces the amount of code of one page, and makes code more readable.
I've submitted bug 101084 for this issue of not finding controls in the user control on their regular id. This should most likely be in the next Service Release. If you require a fix sooner, you could request an untested build from Developer Support.
Hi, David! Thank you, And what's the date of next Service Release? Alexander
I am not sure of the exact date, but I would assume it to be sometime in February. It is usually slightly dynamic as last minute fixes get in or if testing is completed sooner. I would contact Developer Support so that you can be appraised of exactly when the SR ships with this fix.

Hello Alexander,
I have created private support case CAS-83631-NSWZMZ for you. I will link this support case to development issue 101084.
As per my understanding, the next service release for ASP.NET is projected on March 8th. Refer to the link below that will give more details on this:
<http://es.infragistics.com/support/service-releases.aspx#ServiceReleases>
I will update the support case CAS-83631-NSWZMZ for future updates.
David, thank you for your help,
maybe you can look at this problem, it is about keep expanded rows after postback. I think it is quite standard scenario.
