Update not working in detail table

[Jon Ingersoll]

This is the first time I've tried to make a detail table in a radgrid editable. I have a grid with 3 detail tables. I when I've made one of them updatable so far, but when I enter the new information and hit update the form closes and no data is updated. No error is generated either. I'm using ASP:SqlDataSources for my data. Do I need anything extra to get the details table to run an update?

Hello Jon,

You need to set the DataKeyNames property of the table views in the grid so that the insert, update, and delete operations perform as expected.

ASPX:

<telerik:GridTableView DataKeyNames="SOMCourseID,RecordID" DataSourceID="CourseTimeDataSource"
                runat="server" AutoGenerateColumns="False" AllowAutomaticUpdates="true">

Thanks,
Princy.

Thanks, that did the trick.
