I therefore attempted to implement the loading panel for my situation. However, when attempting to run the same code within Share Point, I was not so lucky.
Finally, I was able to get it all to work within Share Point.
Here is how my markup ended up being structured: 1) First I declared the Rad Ajax Loading Panel.
In our situation this took a few seconds and therefore I wanted something to show that data was loading. The Rad Ajax Loading Panel object looked like a great fit.
By default it presents a nice loading animation similiar to what I have seen in Silverlight. NET Framework environment, the Rad Ajax Loading Panel worked like a charm.
I therefore used coding and markup as explained on the Telerik demo site here.
When expanding the master rows to expose the "child" rows, the detail data is loaded on demand via the Detail Table Data Bind event.
That is, in order to use the Check Box Field we must specify the underlying data field whose value is consulted to determine whether the rendered checkbox is checked.
We cannot use the Check Box Field to just include a column of unchecked checkboxes.
NET 2.0 includes a Check Box Field, one might think that it could be used to add a column of checkboxes to a Grid View.
Unfortunately, that is not the case, as the Check Box Field is designed to work with a Boolean data field.
In the preceding tutorial we examined how to add a column of radio buttons to the Grid View for the purpose of selecting a particular record.
