Radgrid datasource not updating Webcam online porno privat
Our problem is that the Telerik data bound controls, when binding to an Entity Data Source, are designed to update the database constantly.
I have a problem that is linked to the fact that the EF normal queries return deleted objects and do not return inserted objects if EF Save Changes has not been called to commit the data to the database.By default all the boundfields will be trasferred as Textboxes in Edit Mode.To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.Suppose if we are trying to hide primary key of our table, there is actually no need to hide. In the above Snippet you are seeing a label in Item Template that means whenever we are showing Grid View to the user Label will be visible to the user.
We will use Template Field, whenever we want to define some custom control in the data bound controls like Grid View, Data Grid or Data Repeater.Secondly if you want to include a custom field (some button or link) in the same column it’s not possible.
