open radwindow depending on validation

[newbie]

I have a button inside the command item template of a grid.

I have the openerelementID of the radwindow set to that button's ID.
However when the user clicks the button I want to run a check to see if the user has selected any rows in the grid or not.
If there are rows selected I want to open the RadWindow where user can give some additional information and if there are no rows selected I want to prompt the user to select a row first and stop the RadWindow from showing.

I added a onclientclick event to the button where I can check whether rows are selected.But right now even if the rows are not selected it gives the prompt and then opens the RadWindow.

How can I stop that from happening?

Hi newbie,

In scenario like yours, OpenerElementID is not suitable. I suggest to open the RadWindow by using its client-side API instead (radopen() or show()). More information on RadWindow's client-side API is available in the documentation, section Controls / RadWindow / Programming.

Thanks.

I am able to open the window but how do I attach the Clientcallback function to the window opened with RadOpen?

I used :

var oWnd = $find("<%= DialogPopupAdd.ClientID %>");

oWnd.show();

and it works fine now.

Thanks.

Hello newbie,

You can dynamically set the ClientCallBackFunction by using
oWnd.set_clientCallBackFunction(MyClientCallBackFunction);

where MyClientCallBackFunction is the name of the function that you want to be executed.
