I'm using a tabstrip with a toolbar inside each multi-view (used in conjunction with the tabstrip). I have not gotten around to switching the multi-page for the multi-view since verything is working.

The one problem I'm experiencing is the Toolbar performs a postback (as expected) but doesn't cause the validation controls to execute and "stop" the post back when they fail validation tests. I have an "Add", "Edit", "Delete", "Update" and "Cancel" button on the toolbar and only need the validation controls to execute when the "Update" toolbar item is selected. Is there anything equivalent to "CausesValidation" property or another method of running all validations and stopping the post back when they fail?

Hi James,

Thank you for your interest in Syncfusion Products.

Could you please provide us more information on what do you like to validate when the 'Update' toolbar item is clicked? Meanwhile, you can also try implementing the validations in the "ClientOnItemSelect" client side event of the Toolbar Item. If the validation fails, you can stop the postback by just returning 'false'. You can find more information of using them in the Online Sample in the link below


Kindly try the above and let us know if this works.

An example of the problem is a Required Field Validator inside an EditItemTemplate of a DetailView control. The DetailView is inside a Multiview control. I have a toolbar that when clicked calls an sub routine in the code behind page using the OnClick="SubRoutineName" attribute. When I click the toolbar item the "OnClick" routine executes but none of the pages validation control execute. If I was using a CommandButton I could set the "CausesValidation" attribute to true and the page validates before the CommandButton's onClicked event executes.

I've worked around the issue but calling the Page.Validate() and then checking the Page.IsValid() property in the toolbar's onClick routine (only when the specific UPDATE toolbar item I'm interested in is clicked) and this works ok, but it seems to me that the toolbar item (since it posts back) should have the ability similiar to a command button to "cause validation" when clicked. I was just hoping there was a property setting I had overlooked.
