    [CLOSED] CheckBoxGroup initial state

    Below is a sample I put together to discuss the CheckBoxGroup CheckItems. After your helped in the previous thread, I now have the following question.

    If I push the 'Get Count' button the answer is 0
    If I select the Calendar button to show the years selected and then push the 'Get Count' button the answer is 1.

    Shouldn't the initial answer also be 1 instead of 0?

    <%@ Page Language="C#" %>
    <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
    <script runat="server">
        protected void GetCheckedItemsCount(object sender, DirectEventArgs e)
            CheckboxGroup group = X.GetCmp<CheckboxGroup>("CheckboxGroup1");
            for (var i = 0; i < group.CheckedItems.Count; i++)
                X.Msg.Alert("Item Selected", group.CheckedItems[i]).Show();
            X.Msg.Alert("DirectEvent", group.CheckedItems.Count).Show();
        protected void CheckBoxChange(object sender, DirectEventArgs e)
            CheckboxGroup group = X.GetCmp<CheckboxGroup>("CheckboxGroup1");
            string strYears = "";
            for (var i = 0; i < group.CheckedItems.Count; i++)
                strYears = strYears + group.CheckedItems[i].RawValue + " ";
            X.Msg.Alert("CheckBox Change", strYears).Show();

    Hi Chris,

    A problem is a fact that a Button's Menu and, respectively, its items (a CheckboxGroup in your case) are not rendered by default. It is rendered on click.

    Therefore no submit before click.

    You could send a required data via a DirectEvent's ExtraParams collection. But I would prefer to use this trick to force rendering.
    <AfterRender Handler="this.showMenu(); this.hideMenu();" />
    It is a Button's listener.

    You got me around an issue again. Thank you. Go ahead and close this thread.
