In editable grid, how do we handle the validations? We need to show the cursor back to the cell?

Requirement:

Assume that we need to display 3 columns in the Grid and one of the columns is required field. When user enters the blank data in edit mode in the required filed, then application needs to show an  alert message and cursor back in the cell. User can able to navigate on any of the other operations in the form like logout or switching to other form, other than Grid operations.

Please provide with sample code.

Thank You,

Hi Sirisha Peyyeti,

You may run through our online documentation - both considering the validation and the validating events. Furthermore, you may take a look at our demos on the same topic. I believe those sources would be quite helpful for achieving the scenario you require.

Hi,

We have gone through the demos and the  validations is working fine, but user cannot able to perform any action in the form.
we need the solution like validating with in the grid and we will not allow  the user to perform any action in the Grid, but he can able to perform any of the actions in the Form (Out of the grid) in such a case we need to show the confirmation to the user. And based on confirmation user proceed next action.

Thank You,

Hi Sirisha Peyyeti,


Indeed, when the validation fails, the corresponding cell keeps the focus. If you try to move it away, a CommitEdit is executed, the validation fails again and the focus stays on that cell. If you want to overcome this, you may set the ActionOnLostFocus property of the grid:

<telerik:RadGridViewx:Name="RadGridView1"  ActionOnLostFocus="None">

Thus when the focus is moved, CommitEdit will not be executed.


Kind regards,
