RADProgress Manager works on Dev machine but not Server

Hi,
I have an application that uses the RADprogress Manager. On my dev machine, it works fine, during the file upload the progress bar appears and updates. I move the application to my production server and the file uploads but no progress area. In reviewing the forums and other support, I've done/checked the following
- Ensure the two registrations are in web.config (the prod srv is the same - I just change the connection string after I load it)
- No Ajax
- tried setting trust level="Full"
- updated to latest assemblies

I did not try registering the assembly in the GAC, as I run several other website on the server and was uncertain of the effect on them.

The production server is windows 2003 with IE 6. It is a dedicated server, not shared. The browser is IE 8. My dev environment is Windows XP, Visual Studio 2008.

The only two differences I can see beyond the OS difference is that on the produciton server, the website runs as a Virtual Directory under a second website that does not have the appropriate registrations in the web.config. I didn't purse that further since upload works. I assume that wouldn't work if it wasn't seeing the registrations
The other difference is the production server is running dotDefender as an application firewall. That firewall has not caused any other code issues..

Thanks for you help,
Bob

Combobox in Custom Control

Hi,

I'm trying to use some combo boxes in a custom control. To get this working I am using AJAX and have a function that I call in the custom control backend that ties the AJAXified controls to the main page's AjaxManager. This works for the radnumerictextbox controls on the page but for the radcombobox controls the selected index changed event doesn't fire. If I take the controls out of the custom control and run them in a standard web page it works fine. Any ideas? Code is below:

Custom control webpage:

    
                <tr> 
        
                    <td class="label">Start Date Modifier:</td> 
        
                    <td class="halfWidth">  
        
                        <telerik:RadNumericTextBox ID="uxStartDateModInterval" runat="server" Width="30" DataType="System.Int16" MaxValue="100" MinValue="-100" AutoPostBack="True" ><NumberFormat DecimalDigits="0" /></telerik:RadNumericTextBox> 
        
                        &nbsp;  
        
                        <telerik:RadComboBox ID="uxStartDateModIntervalTypeID" Runat="server" Width="90" MarkFirstMatch="True" AutoPostBack="True" OnSelectedIndexChanged="uxStartDateModIntervalTypeID_SelectedIndexChanged">  
        
                            <Items>

                    </td> 
        
                </tr> 
        
                <tr> 
        
                    <td class="label">End Date Modifier:</td>

                    </td> 
        
                    <td class="labelBlackLeft" colspan="2">  
        
                        <asp:label ID="uxEndDateExample" runat="server" Text="Ensure both fields have data."></asp:label> 
        
                    </td> 
        
                </tr>

Custom control codebehind

    
                    Public Sub SetupAJAX(ByRef radAjaxManager As Telerik.Web.UI.RadAjaxManager)  
        
                        radAjaxManager.AjaxSettings.AddAjaxSetting(Me.uxStartDateModInterval, Me.uxStartDateExample)  
        
                        radAjaxManager.AjaxSettings.AddAjaxSetting(Me.uxStartDateModIntervalTypeID, Me.uxStartDateExample)  
        
                        radAjaxManager.AjaxSettings.AddAjaxSetting(Me.uxEndDateModInterval, Me.uxEndDateExample)  
        
                        radAjaxManager.AjaxSettings.AddAjaxSetting(Me.uxEndDateModIntervalTypeID, Me.uxEndDateExample)  
        
                    End Sub 
        
                    Protected Sub uxStartDateModIntervalTypeID_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles uxStartDateModIntervalTypeID.SelectedIndexChanged  
        
                        ModifyDate(uxStartDateModInterval, uxStartDateModIntervalTypeID, uxStartDateExample, False)  
        
                    End Sub 
        
                    Protected Sub uxEndDateModIntervalTypeID_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles uxEndDateModIntervalTypeID.SelectedIndexChanged  
        
                        ModifyDate(uxEndDateModInterval, uxEndDateModIntervalTypeID, uxEndDateExample, False)  
        
                    End Sub 
        
                    Protected Sub uxStartDateModInterval_TextChanged(ByVal sender As Object, ByVal e As EventArgs) Handles uxStartDateModInterval.TextChanged  
        
                        ModifyDate(uxStartDateModInterval, uxStartDateModIntervalTypeID, uxStartDateExample, False)  
        
                    End Sub 
        
                    Protected Sub uxEndDateModInterval_TextChanged(ByVal sender As Object, ByVal e As EventArgs) Handles uxEndDateModInterval.TextChanged  
        
                        ModifyDate(uxEndDateModInterval, uxEndDateModIntervalTypeID, uxEndDateExample, False)  
        
                    End Sub

Finally on the page that has the custom control placed on it I use the following in the Page_Load event...

    
            uxDateModifierControl.SetupAJAX(uxRadAjaxManager)

Where uxDataModifierControl is the custom control ID....

Any thoughts?

Regards,

Jon

Textbox in RadTreeView: Can't select text

Hey everyone,

I've got a Textbox being placed inside a RadTreeNode. It all works great, except I can't select any text, either by clicking and dragging, or by using shift and the arrow keys. Is there any easy way I can fix this?

Note: at first, hitting enter didn't work either, but then I found this post:

http://www.telerik.com/community/forums/aspnet-ajax/treeview/radtreeview-control-with-textbox-space-issue.aspx

edited the code a tiny bit, and that works fine now. I tried editing it a bit more to allow for shift-arrowing, but to no avail.

Thank you,

Tommy Walsh

Monitor Upload Progress in Dynamic Data Field Template

I have a custom field template for choosing / uploading images in my dynamic data project.

The uploading worked fine pretty much out of the box, but I just can't figure out how to get the progress manager / progress area to work. Basically need to provide users with feedback as their files are being uploaded in the DynamicData web application. My Edit page templaet is plain vanilla:

    
            <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server"> 
        
                <asp:DynamicDataManager ID="DynamicDataManager1" runat="server" AutoLoadForeignKeys="true">

                    </DataControls>

zero length file after upload

Hi, I am using upload and the gridbinary column pretty much right out of the samples found elsewhere on this site. I am not even bothering with upload progress bars, etc. and there is no ajax involved. I am using Q3 2009, and the Uploaded file name is present, but the length is zero - I am trying to read into a byte array but there is nothing to read into. Here is a code frag - if anyone knows what I am doing wrong here, please let me know.

Dim editItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)
                    Dim upload As RadUpload = DirectCast(editItem.EditManager.GetColumnEditor("Upload"), GridBinaryImageColumnEditor).RadUploadControl
                    Dim MyUploadedFile As Telerik.Web.UI.UploadedFile = upload.UploadedFiles(0)

                    Dim MyFileName As String = MyUploadedFile.FileName ' this evaluates to the file I am uploading
                    Dim fs As System.IO.Stream = MyUploadedFile.InputStream ' fs.length is always zero.

                    Dim picture As Byte() = New Byte(fs.Length - 1) {}
                    fs.Read(picture, 0, fs.Length - 1)
                    fs.Close()

[Solved] How to make a tree view like frameset click?

Dear all,
I have just bough the whole package of telerik and I think they should be good to go in my project :)

My question is, in asp.net treeview control, there is a property call "NavigateUrl" and if u click on it, it will redirect to another page with whole page refresh, and then the state of treeview is clean.I know the answer is the new page is a link, so it would be considered as a new page. How does this radcontrol to handle this saturation? Such as saving the treeview state, and click on the node with no refreshing...I know there is multipage of radcontrol, but I think that will be preloaded all of my pages in multopage, so it will slow down the process...

Please advice, thx.

Best regards,
Stephen

Almost 500 rows is bind to the combo at run time.

    
            <telerik:RadComboBox ID="RadComboBox_SchoolName_Search" runat="server" Skin="Default" 
        
                                    Width="575px" Font-Names="Arial" HighlightTemplatedItems="true" MarkFirstMatch="true" 
        
                                    AutoPostBack="true" EnableTextSelection="true" EnableItemCaching="true"> 
        
                                    <HeaderTemplate> 
        
                                        <table style="text-align: left; width: 575px"> 
        
                                            <tr> 
        
                                                <td style="width: 400px; font-weight: bold;"> 
        
                                                    School Name 
        
                                                </td> 
        
                                                <td style="width: 175px; font-weight: bold;"> 
        
                                                    State 
        
                                                </td> 
        
                                            </tr> 
        
                                        </table> 
        
                                    </HeaderTemplate> 
        
                                    <ItemTemplate> 
        
                                        <table style="width: 630px; text-align: left"> 
        
                                            <tr> 
        
                                                <td style="width: 430px;"> 
        
                                                    <%# DataBinder.Eval(Container.DataItem, "SchoolName")%> 
        
                                                </td> 
        
                                                <td style="width: 200px;"> 
        
                                                    <%# DataBinder.Eval(Container.DataItem, "State")%> 
        
                                                </td> 
        
                                            </tr> 
        
                                        </table> 
        
                                    </ItemTemplate> 
        
              <CollapseAnimation Duration="200" Type="None" /> 
        
                                </telerik:RadComboBox>

and bind using

    
             private void Populate_RadComboBox_SchoolName_Search() 
        
                { 
        
                    DataTable _SchoolwithState = new DataTable(); 
        
                    _SchoolwithState.Clear(); 
        
                    RadComboBox_SchoolName_Search.Items.Clear(); 
        
                    _SchoolwithState = objLookup.Populate_SchoolwithStatename(); 
        
                    if (_SchoolwithState.Rows.Count > 0) 
        
                    { 
        
                        if (_SchoolwithState.Rows.Count > 15) 
        
                        { 
        
                            RadComboBox_SchoolName_Search.Height = 410; 
        
                        } 
        
                        RadComboBox_SchoolName_Search.DataSource = _SchoolwithState; 
        
                        RadComboBox_SchoolName_Search.DataTextField = "SchoolName"; 
        
                        RadComboBox_SchoolName_Search.DataValueField = "SchoolID"; 
        
                        RadComboBox_SchoolName_Search.DataBind(); 
        
                    } 
        
                    RadComboBox_SchoolName_Search.Items.Insert(0, new RadComboBoxItem("---Search Students by School Name---")); 
        
                }

At run time, I have to wait for a long time to load the drop down after clicking the arrow.
Is there any other methods to make it fast.
Please help.

radUpload loadedcontrol in ajax multipage

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.
