What is the proper use of validation in a grid for propertiestextedit? I want to ensure fields contain data ... if left blank, they presently return an "Object reference not set to an instance of an object" error. Thanks in advance!

Hi Bryant,

Take a look at the following demos:

Validation 

How to validate EditForm editors

Thanks.

Thanks, this works great for editing existing records!

However, it does not cure the error message when adding a new record. 

Is there a different event than CellEditorInitialize that should be monitored?
 

Hi Bryant,

The control must have focus for it work. So make sure you click within the control and then it will activate the validation. I just tested the validation for new records and it works fine.

Take a look at this help topic:

• Row Validation and Error Indication
• How to: Validate Rows
  

Also, I've updated this demo to show how the new button can do validation on click of the Update/Insert:

How to validate EditForm editors

Thanks. 

Hi my name is Armando and I'm new using the developer express asp.net controls. I have an evaluation version of the ASP.NET controls and I am trying to use them in a new project, specifically I am using an ASPxGridView in a Web User Control and I have two questions. I was trying to validate one of the fields in the grid but I realized that in the ValidationSettings there is not an option to specify a dynamic behavior for the validation like the ASP.NET validators provided with Visual Studio, due to this there is an extra space at the side of the control in the EditForm Template control that I am validating and I don’t like this extra space, then I tried to use the RequiredFieldvalidator but it does not work with ASPxTextBoxes or at least I did not find the way to do it. My first question is: Is there a possibility to have a dynamic behavior in ValidationSettings or a workaround to use the RequiredFieldvalidator with ASPxTextBoxes?.

The second question is related with the event CellEditorInitialize if I do not specify a template for the EditForm this event is fired but if I specify a template this event is not fired. So my second question is: Is it possible to fire this event, I mean use this event if I specify a template for the EditForm in the ASPxGridView?

Thanks a lot in advance.

Armando
