Hello Experts,

I have DDL1,DDL2, DDL3 cascading drop downs
I already have Please wait dialog Jquery working for other things.
I want to write a Jquery when DDL1 is selected and DDL2 is loading, I will call the Jquery ShowpleaseWait() function. But I don't know how to write when my ASP.Dropdownlist DDL1 is selected in JQuery

Can anyone help me in telling me how to write DDL1.selected change then call the method ShowPleasewait() in Jquery?

Just use "blockUI" jquery pluggin. Simply use $.blockUI(); to block and $.unblockUI(); for unblock the screen. For more settings like showing a spinning image under text "Please wait" or any custom CSS, goto below link. Its very easy.

Well, Actually, I tried it but what happended is
DDL1 is selected and JQuery starts...and stops then
DDL2 is loaded based on DDL1 Selected value...
But I want to Stop the Jquery only when DDL2 is bound.
I hope that makes sense
