Use installer or manual methd to update to Q2 2009

Hi

I may be being over-cautious, but I am not sure from the online install instructions if it is
best to use the installer msi or to install manually for this update?

I am using vwd 2008 SP1 and already have Q1 2009 (3.5) installed.

Please straighten me out!

Thanks

Clive

RadAjaxManager doesn't send async postbacks

Greetings all!

I have a strange issue in my test app. The prerequisites are as follows:

1. I have an aspx page featuring a standard asp.net ajax scriptmanager control as well as my own user control.

2. The user control of mine has only two things in it: RadAjaxManagerProxy plus RadGrid. The manager proxy is configured to update the grid on any postbacks from the grid (e.g. paging or sorting).

The issue is that regular postbacks still occur when say sorting the grid. Placing the grid into an RadAjaxPanel (and removing the manager of course) fixes the issue. But why the hell doesn't it work with the manager proxy? I made sure the control IDs are correct in the manager settings. I also made sure Ajax postbacls aren't disabled in the manager.

Best regards,

Andreii

Selected index changed for resource collection

Hi:

I have a drop down populated with a list of values on the advanced form. Depending on the value chosen in the drop down I want to be able to set the description and the end time to a certain value. How can I achieve this ? In the .net world I would have done it in the selected index changed event of the drop down but with the rad scheduler I dont know how can I create such an event.

Thanks,

Aditya

Upload fails but no error

I ahve a page with RadUpload on it.

There's no Ajax and I'm not currently using File Validation.

When I upload a file, the progress indicator shows as if the file is being updated and at the end of the process UploadedFiles.Count == 1 but there's nothing in the target directory.

No error is thrown.

Why is it eating my files?!?!?!

Filter Menu Issue With RadGrid

Hi All

I am using Telerik 2009 version. I am using a telerik grid to bind some data. The grid i am binding uses some special formatting so for that i have made EnableEmbeddedSkins as "False" enableTheming as "False" and SKin="" and hence i am able to add some effects on my rows of telerik Grid. If i donot use Skin="" then i am getting ugly buttons in place of Expand Collapse button images and Filter menu Options and if i am using SKin as "" then i am getting the desired things(i.e images)

BUT the issue comes with the filter menu, i want to add skin to the filter menu and for that i have added EnableEmbeddedSkins as "True" enableTheming = "True" and SKin="Gray" but i am not getting any skins over there which is making the Filter Menu ugly(i.e without any skin) please help me for the same that how can i apply the skin without losing my color properties that i have set for the Grid.

Any Immediate help will be highly appreciated.. Thanks Ahead!!

Force postback only on AjaxRequest

Hi,

I would like to set EnableAjax to false on the AjaxManager but only when the request is triggered via the OnAjaxRequest property and not when every other Ajax request is called.

Example in the documentation states I can force a postback via:

    
            function onRequestStart(sender, args) { 
        
                        args.set_enableAjax(false); 
        
                    };

This works fine but it will of course stop all my Ajax requests will it not?

I was hoping I could do:

    
            function ajaxRequest() { 
        
                        var ajaxManager = $find("<%= ajaxManager.ClientID %>"); 
        
                        ajaxManager.set_enableAjax(false); 
        
                    }

or

    
            protected void ajaxManager_AjaxRequest(object sender, AjaxRequestEventArgs e) 
        
                { 
        
                    ajaxManager.EnableAJAX = false; 
        
                    // then call server side code 
        
                }

but neither seem to work. The former because the event does not exist and the latter because it is too late in the page lifecycle to set enable ajax to false. Any ideas how I achieve this please?

[Solved] SelectedValue From Code Behind

Hi,

I am converting a regular asp:drodownlist to a rad ComboBox. It is a year drop down that gets populated on a formula from the code behind. However, I can't seem to get the SelectedValue from the ComboBox in the same way I can from the asp:dropdownlist.

Here is my code behind for populating the asp:dropdownlist:

    
            private void BindYears() 
        
                { 
        
                    DateTime firstyear = DateTime.Now.AddYears(-62); 
        
                    for (int i = 0; i > -47; i--) 
        
                    { 
        
                        DateTime year = firstyear.AddYears(i); 
        
                        ddlYear.Items.Add(new ListItem(year.Year.ToString())); 
        
                    } 
        
                    ddlYear.SelectedIndex = 0; 
        
                }

I changed "ListItem" to "RadComboBoxItem" and the combobox populated correctly. However, upon postback of the combobox value I got an error as if the 'Value' wasn't being read.

Here is the codebehind for pulling the values from the dropdowns:

    
            private int Month 
        
                { 
        
                    get { return Convert.ToInt32(ddlMonth.SelectedValue); } 
        
                    set { ddlMonth.SelectedValue = value.ToString(); } 
        
                } 
        
                private int Day 
        
                { 
        
                    get { return Convert.ToInt32(ddlDay.SelectedValue); } 
        
                    set { ddlDay.SelectedValue = value.ToString(); } 
        
                } 
        
                private int Year 
        
                { 
        
                    get { return Convert.ToInt32(ddlYear.SelectedValue); } 
        
                    set { ddlYear.SelectedValue = value.ToString(); } 
        
                } 
        
                public DateTime SelectedDate 
        
                { 
        
                    get 
        
                    { 
        
                        try 
        
                        { 
        
                            DateTime selecteddate = Convert.ToDateTime(Month + "/" + Day + "/" + Year); 
        
                            return selecteddate; 
        
                        } 
        
                        catch 
        
                        { 
        
                            throw new Exception("The date you selected is not valid"); 
        
                        } 
        
                    } 
        
                    set 
        
                    { 
        
                        try 
        
                        { 
        
                            Month = value.Month; 
        
                            Day = value.Day; 
        
                            Year = value.Year; 
        
                        } 
        
                        catch (Exception ex) 
        
                        { 
        
                        } 
        
                    } 
        
                }

These worked fine for asp:dropdownlist and for statically configured radcomboboxes. No on the dynamic "year" when using a radcombobox.

Stuck. Any help would be appreciated. Thanks.

Selecting Items

Hi (again),

I have the following ListView definition:

                    <telerik:RadListBox ID="radListBoxGroups" runat="server"         
                                                                AllowDelete="false"          
                                                                AllowReorder="false"         
                                                                AllowTransfer="true"         
                                                                AllowTransferDuplicates="false"         
                                                                AllowTransferOnDoubleClick="true"         
                                                                CheckBoxes="false"         
                                                                SelectionMode="Multiple"         
                                                                TransferMode="Move"         
                                                                Height="300"         
                                                                Width="180"         
                                                                TransferToID="radListBoxGroupsSelected"         
                                                            >         
                                                                <ButtonSettings Position="Right"          
                                                                    RenderButtonText="false"          
                                                                    ShowDelete="false"          
                                                                    ShowReorder="false"          
                                                                    ShowTransfer="true"          
                                                                    ShowTransferAll="false"          
                                                                    VerticalAlign="Middle" />         
                                                            </telerik:RadListBox>         
                                                            <telerik:RadListBox ID="radListBoxGroupsSelected" runat="server"         
                                                                Height="300" Width="170">         
                                                            </telerik:RadListBox>         

And I use the following code to populate it:

                                var query = from dg in _dataGroups         
                                    join dgi in _originalDataGroupItems on dg.ID equals dgi.ParentDataGroup.ID into sr         
                                    from x in sr.DefaultIfEmpty()         
                                    select new { DataGroupID = dg.ID, IsEnabled = x != null, DataGroupName = dg.Name };         
                     
                        foreach (var q in query)         
                        {         
                            RadListBoxItem radListBoxItem=new RadListBoxItem(q.DataGroupName,q.DataGroupID.ToString());         
                            radListBoxGroups.Items.Add(radListBoxItem);         
                            if (q.IsEnabled)         
                            {         
                                radListBoxItem.Selected = true;                          
                            }         
                        }         

I have traced through and some items are set to Selected==true, yet the ListView does not reflect this. The UI does not move items to the right-hand list and the SelectedItems collection returns Count==0.

What am I doing wrong?
