object.IsFormSubmitted
This property determines whether editable grid processing is performed in show or in postback mode. In show mode, the grid’s fields are assigned values from the data source (or none when inserting). In postback mode, user provided data is available for processing.
This property may be used to specify different behavior in show and in postback mode. Using this property in combination with EditMode property allows to determine all possible form states.
Note: Usually, the browser is redirected (using Return
Page property setting) after successful submit processing and any modifications
made to form's view depending on IsFormSubmitted = true
condition will
be visible only if validation fails.
The following example displays specific warning message when the form is in failed
validation mode. If validation succeeds, no visible effects are output and the browser
is redirected.
The code assumes the grid is called EditableGrid1, the label which will display
the error message is called Label1. This code may be used in form's
Before Show event.
If EditableGrid1.IsFormSubmitted Then EditableGrid1.Label1.Value = "Please don't use browser's Refresh button.<br>Correct validation errors and resubmit." End If
