Hi All,

How do we know when the upload is complete. My program takes in a file and converts it into a pdf file after upload and then i need to stream it back to the browser. I am not sure how to track the upload complete on the browser side so that i can initiate another page after the upload to stream the pdf. i would like to do this initiation through a javascript, i am not sure which event i should track on the client side to do this soon after the upload is complete.

thanks
Sunil

Ajax Refresh user Controls

I have a user Control containing this:

    
            <%@ Register Src="~/uc1.ascx" TagName="test" TagPrefix="uc1" %>   
        
            <%@ Register Src="~/uc2.ascx" TagName="test"TagPrefix="uc2" %> 
        
            <uc1:test ID="uc1" runat="server" />   
        
            <uc2:test ID="uc2" runat="server" />

Code Behind:

    
               protected void Page_Load(object sender, EventArgs e)   
        
                 {  
        
                    RadAjaxManagerProxy AjaxManager = (RadAjaxManagerProxy)this.FindControl("RadAjaxManagerProxy1");   
        
                     AjaxManager.AjaxSettings.AddAjaxSetting(uc1.FindControl("Button1"),uc2.FindControl("TextBox1"));   
        
                 }

User Control 1 is

    
            <%@ Control Language="C#" AutoEventWireup="true" CodeFile="uc1.ascx.cs" Inherits="App_TelusPHR_uc1" %>   
        
                <asp:Button ID="Button1" runat="server" Text="Button" />

User Control 2 is

    
              <%@ Control Language="C#" AutoEventWireup="true" CodeFile="uc2.ascx.cs" Inherits="App_TelusPHR_uc2" %>   
        
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

code Behind

    
               public static int count = 0;   
        
                protected void Page_Load(object sender, EventArgs e)   
        
                {  
        
                count++;  
        
                TextBox1.Text = count.ToString();  
        
                }

User control 2 is never refreshed..... any idea?

Specified argument was out of the range of valid values

Hi, I'm having a problem with a Grid, the thing is that I automatically expand the items and save the expand state when an update is done...but sometimes brings me this error:
Specified argument was out of the range of valid values.
Parameter name: ItemHierachicalIndex
I got the code to keep the state of the grid, from a telerik forum; this is where the page marks me the error

Protected Sub RadGrid1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.DataBound

'Expand all items using our custom storage

Dim indexes As String() = New String(Me.ExpandedStates.Keys.Count) {}

Me.ExpandedStates.Keys.CopyTo(indexes, 0)

Dim arr As New ArrayList(indexes)

'Sort so we can guarantee that a parent item is expanded before any of

'its children

arr.Sort()

For Each key As String In arr

If key Is Nothing Then

Else

Dim value As Boolean = DirectCast(Me.ExpandedStates(key), Boolean)

If value Then

------------------------>>>>>> RadGrid1.Items(key).Expanded =

True <<<<<<<---------------------

End If

StyleSheetManager Combine and AJAX

I'm having an issue with the RadStylesheetManager not combining the css files on AJAX requests. The RadStylesheetManager works properly on the intial page request, but on AJAX requests I see individual WebResource requests to WebResource.axd and not Telerik.Web.UI.WebResource.axd. The RadScriptManager residing on the same page works as expected during AJAX requests combining the script files for the controls and using the Telerik handler. I've tested this with both Fiddler and Firebug and tried this with both IE and FireFox using both Q3 2008 and the latest nightly build of Q2 2009.

Any help would be appreciated.

Thanks
Matt

Error when hitting Enter in TextArea

Hi,

When predefining content in a TextArea you get an Unspecified error when hitting Enter.
To reproduce this:

Open Internet Explorer 8 (other versions seem to have the same problem, but I cannot confirm. Firefox apparentally does not allow to predefine content in a Textarea inside the RadEditor).
Go to a website with a RadEditor, eg: http://demos.telerik.com/aspnet-ajax/editor/examples/autosave/defaultcs.aspx
Add a Textarea element.
Hit <Enter> (given that the caret is in the Textarea, otherwise doubleclick on the Textarea before hitting <Enter>)
A messagebox pops up stating Unspecified error

I know that using <Shift> + <Enter> does the trick. But is there a way to either accept the <Enter> as a newline or display a custom error message?

Thanks in advance,
Dries

Problem regarding nestedviewtemplate and executing javascript functions client side

Hello,
I've been trying to do something that has a problem.

I have a RadGrid with a nestedviewtemplate. Inside this newstedviewtemplate i have 3 tabs with another radgrid (1st tab), several control (2nd tab) and a repeater (3rd tab).

I've been trying by client side, when i change the values in the 2nd tab (several controls) I need to place a checkbox with checked=true. My problem has been trying to do this when changing the selected date in a RadDatePicker.

Mensagem: O objecto não suporta esta propriedade ou método

The line of code of when I try to change the attributes in the server side (when executing the expandall command in the first radgrid) is this:

rDatePickerInicial.ClientEvents.OnDateSelected = "ChangeCheckBox('" + ckChanges.ClientID + "')";

The code for asp.net textbox is:

txtDescricaoPt.Attributes.Add(

"onkeypress", "javascript:ChangeCheckBox('" + ckChanges.ClientID + "')");

txtDescricaoGb.Attributes.Add(

"onkeypress", "javascript:ChangeCheckBoxCheckBox('" + ckChanges.ClientID + "')");

and this works.

My only problem has to do with Telerik controls.
