    Hi

    I want to set the selected value to jqxdropdownlist on pageload

    For suppose I have items a,b,c,d in the dropdownlist, now i want to set ‘c’ as selected value dynamically on page load dynamically.

    Don’t give suggestions like  put selected index, I want to set value directly as selected value.

    How can i achieve it…..

    plz  help me urgent Thanks in advance!

    Hello narendra.pvnb,

    To do this, use the val method:

    $("#jqxDropDownList").jqxDropDownList('val', 'c');

    Remember to update to version 2.8, too.

    Hi narendra.pvnb,

    You have to initialize the dropdownlist first to be able to call its methods. An example initialization can be seen in the documentation entry Getting Started. Also note that it should be:

    $("#jqxClient_Role").jqxDropDownList('val', role);

    and not:

    $("#jqxClient_Role").jqxdropdownlist('val', role);

    Hi narendra.pvnb,

    Have you implemented the widget’s initialization? Please browse the Editing Grid demo section for some useful examples on the matter.

    Hi narendra.pvnb,

    Here is the solution. The example is based on the demo Popup Editing and uses jQWidgets version 2.8.

    To save the changes, click the 'Save' button in the popup dialog. To cancel the
