Hi,
I'm using the Radinputmanager to style textboxes in a RadGrid. However, different validation rules exist for the textboxes in the grid. Some of them are required fields, while others must have a numeric value greater than zero.
Can I do such validation with the Radinputmanager or do I need to make some custom validation? If so, how do I prevent the grid page from posting back the page, if the custom validator or requiredfieldvalidator returns false?
Best regards
Henrik

Hello Henrik,
I think that you can take this online demo of RadGrid as a starting point for your implementation:
http://demos.telerik.com/aspnet-ajax/input/examples/radinputmanager/dynamicinputfiltersettings/defaultcs.aspx?product=grid
It illustrates how to apply different validation rules for the grid edit form editors based on their data type. Note that you can specify IsRequired = true for some of the input manager settings in order to make a particular field in the edit form required. These validation rules should automatically block the postback request when you attempt to update a record or trigger submit from other button which causes validation.
You can see that in action for the ProductName field on this online demo.
