    Cannot use recognise AjaxEvents


    Code in my .aspx file
    


<ext:Anchor>


<ext:ComboBox StoreID = "storeChuyenDe" DisplayField = "Chuyende" ValueField = "IDChuyende" ID="cboKhuVuc" runat = "server" EmptyText = "Khu V?c" X= "100" Y = "5">


<AjaxEvents>


<Change OnEvent = "cboKhuVuc_Change"></Change>


</AjaxEvents>


</ext:ComboBox>


</ext:Anchor>
    And this is my code in .aspx.vb
    


[AjaxMethod]


public void cboKhuVuc_Change()


{


int maKhuVuc = Convert.ToInt32(this.cboKhuVuc.SelectedItem.Value);


BindcboNoiBanHanh(maKhuVuc);


}

    The prolem is that when I build the website, VS display following error message:

    Error 1 No overload for 'cboKhuVuc_Change' matches delegate 'Coolite.Ext.Web.ComponentAjaxEvent.AjaxEventHandl er' D:\MyProjects\QuanLyCongVan\Website\AddCongVan.asp x 74

    I try to change to other event as Select, CHange, but it still display error
    The same happen to other controls when call ajax events

    I guess I have to install something to read ajax from aspx file

    I am using VS.Net 2005

    Could anybody tell me how .... THANKS

    RE: Cannot use recognise AjaxEvents

    Anyone help me please, I think that is common issue
    I cannot catch event by AjaxEvents
    I have used this control VB.Net, and it work fine
    The problem I get when I change to user C# and VS2005

    RE: Cannot use recognise AjaxEvents

    I have found it, this maybe unsupported feature of Coolite
    I use Masterpage, and by searching on google I found that we have to add event in code for each controls when Page is Innited
    But now, I remove all and then use normal page, not MasterPage

    RE: Cannot use recognise AjaxEvents

    Hi,

    You should use the following...

    Example (.aspx)

    <ext:Anchor>
    <ext:ComboBox 
        ID="cboKhuVuc" 
        runat="server" 
        StoreID="storeChuyenDe" 
        DisplayField="Chuyende" 
        ValueField="IDChuyende" 
        EmptyText="Khu V?c" 
        X="100" 
        Y="5">
        <AjaxEvents>
            <Change OnEvent="cboKhuVuc_Change" />
        </AjaxEvents>
    </ext:ComboBox>
</ext:Anchor>
    Example (.aspx.cs)

    public void cboKhuVuc_Change(object sender, AjaxEventArgs e)
{
    int maKhuVuc = Convert.ToInt32(this.cboKhuVuc.SelectedItem.Value);
    BindcboNoiBanHanh(maKhuVuc);
}
    Hope this helps.

    RE: Cannot use recognise AjaxEvents

    Oh, thank you geoffrey, I change the eventhandler to AjaxEventHandler, and it work well
    but it just work when I don't use FileField (I mean don't click on Browse button of FileField control).When click on btn Browse of FileField control, all other button cannot render to code behind
    These are my atual code on .aspx and aspx.cs. I have removed the masterpage
    Please have a look and help me. Thanks

    RE: Cannot use recognise AjaxEvents

    Hi,

    I get an Exception when I try to run your sample. Is all that code required to reproduce the problem? Can you make a very simple sample which only demonstrates the minimum amount of code required to reproduce the problem.


    Also, the following example may help in solving the problem, see

    RE: Cannot use recognise AjaxEvents

    Hi,

    You can extend the timeout by adding the following node inside the <system.web> node of your web.config.


    Example


    <httpRuntime maxRequestLength="524290" executionTimeout="1800" />

    Adjust the maxRequestLength value to meet your requirements.


    Hope this helps.
