Questions on UI for ASP.NET AJAX Forum

I am not sure that I totally understand the way that the radasyncupload control works. What I am trying to do is to have a page that lets users upload files, but there can be no postbacks at all on that page. Everything else that happens on the page uses ajax calls to an API on the server.
Is it possible to do what I am trying to do? I can see that the files are getting uploaded to the temp folder on the server, but the final part of the process where the uploaded event fires doesn't happen until a postback occurs.

[Solved] setting label value to selected combobox value?

HI there! Pretty simple question and probably very simple answer, haha.

I have a combo box that has a couple of values in it (Invoice, Quote). I also have a label or two.

I'd like to set the labels to whatever the combobox is currently set to.

By default the box is set to Invoice, so the page would go something like:

Is this an invoice or a quote? [RadComboBox:Invoice]
Ok, this will be marked as [Label:Invoice].

If the user clicks the combobox and selects Quote, I would like the label to also change to Quote without having to submit anything, just change the label on the fly as the combo box changes.

I assume I would need to use the RadComboBox_DropDownClosing function?

Retrieve RadGrid control dropdownlist selected values

I have RadGrid with DropDownlist. I am trying to find the value of each control by loop through using Javascript. I am getting the findcontrol as 'null'. I have attached OnClientRatingSelectedIndexChanged in code behind for the dropdownlist 'Drop1'. What could be wrong? I appreciate any suggestions.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" AlternatingItemStyle-HorizontalAlign="Left"
                               OnNeedDataSource="RadGrid1_NeedDataSource">
                                <MasterTableView DataKeyNames="level_id" PageSize="10">
                                    <Columns>
 <telerik:GridTemplateColumn UniqueName="TemplateColumn" HeaderText="Test"
                                            Visible="true">
                                            <ItemTemplate>
                                                <asp:Panel ID="Panel1" runat="server">
                                                    <asp:DropDownList ID="Drop1" runat="server"                                                                                                                                        AutoPostBack="true">
                                                    </asp:DropDownList>
                                                </asp:Panel>

                                  </Columns>
</MasterTableView>
</telerik:RadGrid>

Javascript

function OnClientRatingSelectedIndexChanged(arg) {

        var grid = $find("<%=RadGrid1.ClientID %>");
        var MasterTable = grid.get_masterTableView();
        var Rows = MasterTable.get_dataItems();
        for (var i = 0; i < Rows.length; i++) {
            var row = Rows[i];
            var drop1 = row.findControl("Drop1");  
            var val1 = drop1.selectedValue;

[Solved] using window with notification

I have a button defined inside a RadWindow content template that I want to run server code in ajax. The button is inside a RadAjaxPanel. when the server code is run, it could trigger a RadNotification, which is also on the page inside its own RadAjaxPanel.

It all seems to work sort of the first time it's run. The button is clicked and the notification is displayed if necessary. Then the user triggers the window again. I like that the textbox retains the previous value. But when the user clicks the button again, it performs a full page postback, instead of an ajax postback. There is nothing on the page that needs to refresh. Also, how do I keep the window open if the code is going to trigger a notification? Here is the code I'm using:

<telerik:RadWindow runat="server" ID="ForgotPasswordWindow" Modal="True" OpenerElementID="LinkButtonForgotPassword" Behaviors="Close" Title="Reset Password"

Height="180px" VisibleStatusbar="False" Width="350px">

<ContentTemplate>

<telerik:RadAjaxPanel runat="server">

<div style="margin: 10px;">

If you already have an account and have forgotten your password, please enter the

email address for your account in the box provided below. A new password will be

emailed to this address.

<div>

<telerik:RadTextBox runat="server" ID="emailAddress"></telerik:RadTextBox>

<telerik:RadButton runat="server" ID="ResetPasswordButton" Text="Submit" OnClick="ResetPassword_Submit"></telerik:RadButton>

</div>

</telerik:RadAjaxPanel>

</ContentTemplate>

</telerik:RadWindow>

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<telerik:RadNotification runat="server" ID="Notifier" TitleIcon="none" ContentIcon="ok" KeepOnMouseOver="False"

Animation="Fade" Position="Center" AutoCloseDelay="2000" ShowCloseButton="False" Height="90" Width="330"

VisibleTitlebar="False" Skin="Silk">

</telerik:RadNotification>

</telerik:RadAjaxPanel>

if (Membership.GetUser(emailAddress.Text) == null)

{

Notifier.ContentIcon = "warning";

Notifier.Show("The system could not find a user with that email address.");

}

else

......

RadAjaxManager and RegisterStartupScript

Hi All,

I have a Probelm.

On my ASPX Site I have an
RadAjaxManager
RadAjaxLoadingPanel

    
                                <telerik:RadAjaxLoadingPanel   
        
                                    ID="RadAjaxLoadingPanel1"   
        
                                     BackgroundPosition="Top" 
        
                                    runat="server" 
        
                                    IsSticky="true" 
        
                                    Skin="Office2007" /> 
        
                                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                                    <ajaxsettings> 
        
                                        <telerik:AjaxSetting AjaxControlID="FormView1">  
        
                                            <updatedcontrols> 
        
                                                <telerik:AjaxUpdatedControl   
        
                                                    ControlID="FormView1"   
        
                                                    LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                                            </updatedcontrols> 
        
                                        </telerik:AjaxSetting> 
        
                                    </ajaxsettings> 
        
                                </telerik:RadAjaxManager>

In the code behind I register some javascripts by setting RegisterStartupScript

    
                        protected void FormView1_ItemCommand(object sender, FormViewCommandEventArgs e)  
        
                        {  
        
                            switch (e.CommandName)  
        
                            {  
        
                                case "Cancel":  
        
                                    //ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CancelEdit();", true);  
        
                                    Page.ClientScript.RegisterStartupScript(this.GetType(), "alertScript", "alert('test');", true);  
        
                                    break;  
        
                                case "Update":  
        
                                    ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind();", true);  
        
                                    break;  
        
                                case "Insert":  
        
                                    ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind('navigateToInserted');", true);  
        
                                    break;  
        
                            }  
        
                        }

But this script only fired if I remove the radajaxmanager.
What's wrong here?

And second. Is there a good example on how I use the ajaxmanger in combination with master and contentpages.

Thanks for help.

Showing update/cancel buttons during edit

I have "auto generate edit column" off and instead added an "edit" button manually because I needed to set it to visible=false in some rows. The event fires properly but when the grid goes into edit mode, the "update" and "cancel" links don't appear.

I need to do either one of the following:

Show the update and cancel buttons or
Use the auto generated edit column but need to know how to access the column. I thought that I could access the button with item("EditCommandColumn").controls(0) but that isn't accessing the control.

Thanks.

Possible to use DropDownAutoWidth to set combo box width?

I am specifying DropDownAutoWidth="Enabled" on the RadComboBox and that works just fine; the dropdown list extends to the width of the longest item.

However, when I then select that item, the input area truncates it. Is it possible to get the width of the drop down list and use that to set the width of the combo box itself (prior to the page displaying)? I've tried retrieving the DropDownWidth in the DataBound event, but it appears to be zero. An alternative I've explored is using the method here to determine a width and then set both the DropDownWidth and the combo box's width to that value, but it seems cleaner to get the width the combo box determines itself if that's possible.

Issue with RadCompression in Windows Azure

Hello,
I uploaded web site with RadControls to Windows Azure.
And there is 500 server error when I clicked RadButton. (See console of browser) (There is not error in my IIS)
So I debugged it and I figured out. The issue is related to RadCompression.
When I removed RadCompression from web.config, the error has not occurred any more.

But I need to use RadCompression so I tried to solve the issue in different ways.
And when I set <urlMappings> to web.config, the error has not occurred any more.

So, I have two questions below.
1. Why an error occur when I use RadCompression without setting <urlMappings> in Azure?
2. What does <urlMappings> have to do with RadCompression?

I attached my test Web Site source and azure site url.
Please refer to it and answer me about two questions.
