    [CLOSED] Custom Search with X.GetCmp

    Hi, I am trying to use below code to get Value of custom search combox in example:

    but it returns nothing. (*I gave ID to combox as cbxTest)
    The code works for regular combox. not sure what i am missing here
        public void Test()
            string a = X.GetCmp<ComboBox>("cbxTest").Value.ToString();

    Please use Page_Init instead Page_Load to create dynamic controls which will be used in other requests

    Thanks you, but the scenario is that custom search is dynamically generated in directevent . when a button is clicked on that form, i would like to get the value of the combobox. so the contorls won't be created in page_init.

    Please post test sample. Are you sure that combo is submitted own value (Request["cbxTest"])?

    All I did is to add the Test button on the custom search example to get value of NOT dynamically created search combobox and I gave id cbxTest to the combox since in the example there is no ID set for the control.
    Not getting anything back with code: X.getCmp<ComboBox>("cbxTest") syntax

    All I did is to add the Test button on the custom search example to get value of NOT dynamically created search combobox and I gave id cbxTest to the combox since in the example there is no ID set for the control.
    I cannot reproduce the issue (as I said you have to use Page_Init in that sample)

    Please post your sample which reproduces the problem

    I adding the code in according to the details you described and tested it, works fine.

    So, please provide us with a full sample to reproduce.

    Here is my test sample.
