Force open/download all files type

Hi, I'm using the 2010Q1 with VS 2008 in VB

I read KP, and samples on working with files extensions and FileExplorer.

I try to change this example (http://www.telerik.com/ArticleFileDownload.aspx?I=bdmh&G=bahm) in order to force IE to ask user for open/download files when they click on open button.
I don't want the display dialog box for any files.

I tryed to replcae

    
             ' The docx files are downloaded ;  
        
                    If Path.GetExtension(physicalPathToFile).Equals(".docx", StringComparison.CurrentCultureIgnoreCase) Then  
        
                        ' Handle .docx files ;  
        
                        Me.WriteFile(physicalPathToFile, "application/vnd.openxmlformats-officedocument.wordprocessingml.document", Context.Response)  
        
                    End If  
        
                    If Path.GetExtension(physicalPathToFile).Equals(".jpg", StringComparison.CurrentCultureIgnoreCase) Then  
        
                        ' Handle .jpg files ;  
        
                        WriteFile(physicalPathToFile, "image/jpeg", Context.Response)  
        
                    End If  
        
                    ' "txt/html" is the default valuse for Response.ContentType property;  
        
                    ' do not download the file. Open in the window ;  
        
                    Context.Response.WriteFile(physicalPathToFile)

by

    
             WriteFile(physicalPathToFile, "", Context.Response)

But it don't work.

It work for ".doc" and ".xls" files (IE ask me if I wan't to download, open ou calcel)
for ".jpg" files IE ask me too if I wan't to open or download it, but there is a telerik box under this dialog box

Object expected when inserting new RadComboBoxItem client side

Hi,

I am trying to add a RadComboBoxItem client side, but am receiving the Object expected error. This is the line of code that fails:

var

comboItem = new Telerik.Web.UI.RadComboBoxItem();

When I debug the javascript, I notice that Telerik.Web.UI does not contain RadComboBoxItem which is why the exception is being thrown. Is there a reference of some sort that I need to include to use this class?

How to visible false one of the tab ( with its radmultipage )

Hi,
I am using RadTabStrip and RadMultipage on my page.
Now, simply on my page load, depending on some criiteria, I need to hide one of the Tab.
When I am setting up Tab to visible false, its not setting up MultiPageView properly and that's tab's multipageview is getting displayed on next tab.
Please remember, I cannot remove that tab at runtime as I have so many controns in that which are used even though its hidden so if I remove tab at runtime, my code will not find those controls and will generate runtime errors so I need to visible false one Tab and its related MultiPageView.
Here is my Tab.

<telerik:RadTabStrip ID="RadTabStrip1" runat="server" SelectedIndex="0" MultiPageID="RadMultiPage1"

Skin="WebBlue" Width="1050px">

<Tabs>

<telerik:RadTab Text="Questionnaire" SelectedCssClass="SelectedTab" DisabledCssClass="DisabledTab" PageViewID="RadPageView1" >

</telerik:RadTab>

<telerik:RadTab Text="Product Information" SelectedCssClass="SelectedTab" DisabledCssClass="DisabledTab" PageViewID="RadPageView2" >

</telerik:RadTab>

<telerik:RadTab Text="Financial & Operational Considerations" SelectedCssClass="SelectedTab" PageViewID="RadPageView3"

DisabledCssClass="DisabledTab">

</telerik:RadTab>

<telerik:RadTab Text="Upload Files" SelectedCssClass="SelectedTab" DisabledCssClass="DisabledTab" PageViewID="RadPageView4" >

</telerik:RadTab>

<telerik:RadTab Text="Financial Use Only" SelectedCssClass="SelectedTab" DisabledCssClass="DisabledTab" PageViewID="RadPageView5" >

</telerik:RadTab>

<telerik:RadTab Text="Submit Request" SelectedCssClass="SelectedTab" DisabledCssClass="DisabledTab" PageViewID="RadPageView6" >

</telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" class="RadMultipageStyle">

<telerik:RadPageView ID="RadPageView1" runat="server">

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView2" runat="server">

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView3" runat="server">

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView4" runat="server">

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView5" runat="server">

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView6" runat="server">

</telerik:RadPageView>

</telerik:RadMultiPage>

Now, on page_load, I simply want to visible false number 5 Tab ( so Its RadPageView will also be visible false ). I tried this.

RadTabStrip1.Tabs[4

].Visible = false;

but what happens is that tab is visible false but "RadPageView5" is getting displayed under its next tab.
So How do I visible false this tab and its pageview, And again, I have to visible it false because I have to use the contols inside that pageview. So I just dont want to display that tab.

Thanks in advance,

TabStrip

Telerik:RadAjaxLoadingPanel doesn't close in Firefox

I have a RadAjaxLoadingPanel on an aspx page which works fine in IE 7, however, in Firefox Version 3..6.13 it keeps on turning even when the page has finished loading. Just wondering if anyone has ever seen this problem? If I disassociate the loading panel control with the RadAjaxPanel then there's no issue on the page it loads correctly.

Self-referencing hierarchy -- child column headers show when no child rows exist

Why do each of the items in a self-referencing hierarchy grid have child columns displayed -- even when there are no children for the item? (Note: I *do* want a row columns displayed if there are child items, just not displayed when there are *no* children.)

I'm implementing a radgrid in 508 mode where the child row column headers are displayed (along with the main column headers). What I want displayed is as follows:

Parent Column 1 | Parent Column 2 | Parent Column 3
Parent row ............
Child Column 1 | Child Column 2 | Child Column 3
Child row .............
Child Column 1 | Child Column 2 | Child Column 3
Child row .............

However, when there's only one child, the following is displayed:

Parent Column 1 | Parent Column 2 | Parent Column 3
Parent row ............
Child Column 1 | Child Column 2 | Child Column 3
Child row .............
Child Column 1 | Child Column 2 | Child Column 3

As you can see, the Child Column headers are showing up childCount + 1 times (if there are no children, a child header row appears anyway).

I've tried hiding the column headers on the ItemCreated event, but haven't been successful.

Here's the code definition corresponding to the grid:

<telerik:RadGrid ID="grdNotes" runat="server" OnColumnCreated="grdNotes_ColumnCreated"

{

if (!CachedApplicationData.UseAssistiveTechnology)

}

if (e.Item is GridNestedViewItem)

{

e.Item.Cells[0].Visible = false;

e.Item.Cells[1].Style.Add(HtmlTextWriterStyle.Padding, "0px");

}

RadWindow uses defaults on 2nd load

I have defined the RadWindowManger, and RadWindow like the following:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server"

DestroyOnClose="true" Opacity="99" RegisterWithScriptManager="true"

 

ReloadOnShow="true" Behaviors="Close" Modal="true" VisibleOnPageLoad="false"

Skin="Hay" AutoSize="true"

 

ShowContentDuringLoad="false"> <Windows> 

<telerik:RadWindow ID="Window1" AutoSize="false" Height="650px" Width="550px"

runat="server" Behaviors="None"></telerik:RadWindow> 

<telerik:RadWindow ID="Window2" AutoSize="false" Height="650px"

Width="1000px" runat="server"

Behaviors="Close,Resize"></telerik:RadWindow> </Windows> </telerik:RadWindowManager>

When I open the window the first time, it works correctly. I then close the window, and try to open the window a 2nd time. It now ignores the specific <telerik:Radwindow> settings, and uses the settings in the <telerik:RadWindowManager> instead. Any work around for this (2009q3)?

window.radopen("MyCoolPage.aspx", "Window1");

Thank you.

Clientside error message on RadGrid

Hi

I am just looking at the Telerik controls as part of an evaluation for some work I will be carrying out but have come up against an error with the RadGrid control.

I have a simple linqdatasource retrieving a firstname and lastname from a contact list. I have implemented a radgrid with paging, filtering, sorting and grouping. The grid brings back the first page of results but I receive the following client side message when I try to navigate to the next page...

sys.webforms.pagerequestmanagerservererrorexception
Exception has been thrown by the target of an invocation

The grid is ajaxified, in a radmultipage that is controlled by a tabstrip.

Any ideas?

thanks

<asp:LinqDataSource ID="LinqDataSource1" runat="server"
 ContextTypeName="TelerikEvalDbDataContext"
 Select="new (first_name, last_name)"
 TableName="contacts">
 </asp:LinqDataSource>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="True"
 AllowPaging="True" AllowSorting="True" DataSourceID="LinqDataSource1"
 GridLines="None" ShowGroupPanel="True" Skin="Vista">
 <MasterTableView DataSourceID="LinqDataSource1">
