radUpload loadedcontrol in ajax multipage

[Pierre]

Hi,

I have many problems to fix this scenario. I need to use one radUploader usercontrol loaded in one ajax multipanel but i can't loaded my files. I have used the conditionalPostback registred from loaded usercontrols to stop ajax refreshing or created a realPostBack in page and registred in page-Load of Loaded usercontrol but still not working.

Use the wizard sample of demo of RadTabs and loading one RadUploader control

<telerik:RadAjaxLoadingPanel  runat="server" ID="LoadingPanel1" IsSticky="true">
    </telerik:RadAjaxLoadingPanel>
    <telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1" LoadingPanelID="LoadingPanel1" >
            <telerik:RadComboBox  runat="server" ID="RadComboTipo" Skin="Vista"  AutoPostBack="true" Width="200px"
             OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"  >
                            <Items>
                                <telerik:RadComboBoxItem Text="Select" Value="-1" Selected="true"></telerik:RadComboBoxItem>
                                <telerik:RadComboBoxItem Text="Case1" Value="1" ></telerik:RadComboBoxItem>
                            </Items>
            </telerik:RadComboBox>
            <div style="height:33px;"></div>
            <telerik:RadTabStrip ID="RadTabStrip1" SelectedIndex="0" runat="server" MultiPageID="RadMultiPage1"
                Skin="Default" CssClass="tabStrip">
            </telerik:RadTabStrip>
            <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" OnPageViewCreated="RadMultiPage1_PageViewCreated" CssClass="multiPage">
            </telerik:RadMultiPage>
    </telerik:RadAjaxPanel>

The LoadedControl in pageView use RadUploader and  page load to register realPostBack and stop the ajax event.

bool isOnClickAttached = false;
        IEnumerator keys = this.buttonSubmit.Attributes.Keys.GetEnumerator();
        while (keys.MoveNext())
        {
            if (keys.Current.Equals("onClick"))
            {
                isOnClickAttached = true;
                break;
            }
        }
        if (!isOnClickAttached)
            this.buttonSubmit.Attributes.Add("onClick", string.Format("realPostBack('{0}', ''); return false;", this.buttonSubmit.UniqueID));

This realpostback is firing but no upload is performed.

Use one ClientEvents-OnRequestStart="conditionalPostback" in RadAjaxPanel1 is not possible in this scenario where controls are loaded in the panel.

The object is one Ajax RadTab and one RadUpload control loaded inside and fonctional. Some suggestions. Thanks.

Hello Pierre,

Using the conditinal postback workaround is actually possible. You can use fireBug or IE Developer tools to find out the ID of your upload button. Then, in the conditionalPostback handler compare the target id with the id of your upload button and if they match - cancel the AJAX behavior.

function conditionalPostback(sender, args)
  {
     if (args.get_eventTarget() == "your submit button ID")
     {
         args.set_enableAjax(false);
     }
}

Alternative approach is to hook on the page_load event of your user control, grab the ID of your upload button and write it to the response, like this:

ClientScript.RegisterClientScriptBlock(this.GetType(), "upload", string.Format("window['upload']={0}", "ID of your submit button"), true);
