I have a radgrid, and 3 of my fields have validators on them. The login_name, password and email have requiredfieldvalidator and the email also has a regularexpression validator. I do not want the fields to be validated while entering data, only when the user clicks the update or insert button. This is becasue I also have a dropdown combo box in the form and when this dropdown combo changes, I have 2 embedded grids that change based on the choice in the combo box. But if one of the 3 fields fails validation, and the user changes the combobox, the 2 embedded grids do not reload. My fix to this would be the validation not occur until update or insert is clicked, but I cant get this work work.

Here are the 3 columns with the validation and then the combobox and one of the embedded grids:



<Columns>
        <telerik:GridEditCommandColumn ButtonType="ImageButton"  UniqueName="EditCommandColumn1">
                    <HeaderStyle Width="20px" />

Hello Laura,

Try setting the CauseValidation property of the combobox to false and check if it makes any difference. Another option is to use ValidationGroup - assign same ValidationGroup to the validators and the Update/Insert button.

Give it a try and let me if this helps.
