Exit from edit mode with validation errors

[Roberto]

Hi,

I have a RadGridView in which the user can edit cells and the content is validated.
The problem is that when an error occour the cell remain in edit mode until the input is validated again.
I would like that the user can add invalid input. Is it possible?

Thanks,
Roberto.

Hi Roberto,

In order to exit from the "error" state, you may just press twice the Esc button. However, if you do not want the validation to fire, you handle the validating events of the grid. You may find more information about Validation in our online documentation.

Hi,

I have a scenario where I present the user with a dialogue comprising: ok, cancel and a grid into which some data is required to be entered. In the scenario in which there is invalid data in a cell the cancel button can NOT be clicked and by that I mean that the only event that gets seems to get fired is the cellvalidating event.

I want the user to be able to cancel irrespective of whether the grid has valid or invalid data in it.

Please advise.

Thanks, Steve

Hello Steve Evans,

In order to meet your requirements for cancelling even an invalid value, you may implement the following logic:
1. Define a RadButton:

<telerik:RadButton Content="Cancel"
                   Command="telerik:RadGridViewCommands.CancelRowEdit"
                   CommandTarget="{Binding ElementName=clubsGrid}"  />

2. Set the Property of RadGridView ActionOnLostFocus:

<telerik:RadGridView Name="clubsGrid"
        RowValidating="clubsGrid_RowValidating"
        ActionOnLostFocus="None"
        ItemsSource="{Binding Clubs}"
        AutoGenerateColumns="False" >

The second steps is necessary as the default behavior of the grid on LostFocus is to commit edit
