Hello Phong,

Please, provide us with more detailed information about your scenario, so that we can reproduce it and be more helpful. Do you want to remove the validation at the UI layer, Data-layer, etc ? 

 

All the best,

- I sent to you an image that shows my problem. Now i want to remove the red message on each cell of gridview. I want to control validating by my side.

Hi Phong,

You can change the appearance and the visibility of your Validation as you edit the template of a TextBox in Microsoft Expression Blend. Working with the  <VisualStateManager.VisualStateGroups> gives you the opportunity to define your own style of the Validation or to remove it with the Property "IsEnabled = False".

Another idea for working with validation is proposed in this blog post. However, here you deal with it validation on property/cell level via DataAnnotaions, but it might be helpful for your project.

Kind regards,

Hi.

Can you show me the detail, I could not understand, I think you have easy way to remove that message. Ex : IsValidateCell = "False"

. Can you give me an example for this situation.

Hi Phong,

For the time being there is no property that can be set in order to remove the validation. What you can do is to use a custom template via CellEditTemplate property of a certain column of the GridVew.
I am attaching you a sample project so that you can see and test the proposed solution. The Validation is removed for the first column. 

I hope this helps.

HI Admin!

I tried your Example already. In your Example and my application too, the red message could not display but had problem that could not complete my issue that I Could not enter new value for that cell . This problem happened with your example and my application too from that i could not change new value for that cell. so please show me how .

Please reply this soon because it's very important to fix this early.

Hi Phong,

You can remove the appearance of the validation pop-up window, but there is no way to remove the validation as a whole.Thus, if you define your field to be "int" you can change its value with another 'int" value, but you cannot insert "string" for example (as it is the case with the first column of the grid in the project I have sent to you).
We will work on the case of bypassing a custom validation (for example to escape validation for a condition if a value is between certain limits as in the case: -50<x<100 ). However, this will be probably available in the next Service Pack.

Sincerely yours,
