Radcombobox clearSelection causes validation

[Wired_Nerve]

I have a radcombobox with a set of items in it.

This combobox is in a radwindow.

If the user opens the radwindow i need to make sure the radcomboboxes selection is set to the empty message and does not cause the required validation control to fire.   On the very first opening of the radwindow all is good, it is when they open the radwindow a second time and I do not want their previous selection selected so I want it set to the Empty Message... 

 You can see in this screen shot the required validator fires after using the comboboxes clearselection javascript code

This is not desired...  Any suggestions...????

Hello Warren,

Thank you for contacting Telerik Support.

I would suggest that you try to add custom validator. The required filed validator will try to validate the text of the input element. 

Let me know if this suggestion is working for you.

I ended up having the javascript side of the code disable the validator and I re-enable it later in the page lifecycle.  Easy enough, your idea would have worked also. 

 

 

THanks

Hello Wired_Nerve,

I was just wondering if you could tell me how you achieved the following please?

"I ended up having the javascript side of the code disable the validator and I re-enable it later in the page lifecycle."

Where exactly do you re-enable the validator? If you could post some of your solution that would be great.

Thanks in advance,

John.
