Intresting problem(RadAjaxManager)

I have a master page and want to put the RadAjaxManager on this page, so that when needed
by content pages that it is avalable. When a content page is loaded that dose not require the
script manager or radajaxmanager, I do not want the script manager producing and scripts, this
would mean that for content pages that dont need it, there is no impact on loading that page, it
would be that the scriptmanager or radajax never existed.

I know I could put the script manager and radajaxmanager on only thet page but I have other pages
with 2 or more content sections that require radajaxmanager.

So what I am looking for is a way to be able to turn on and off the script manager and hide there presents by
program code ?

Thanks Keith

Can I populate a combobox with filenames from a network share?

So they'd like me to create an application where the files from a particular network folder populate into some kind of box with checkboxes, so they can select as many as they'd like and upload them to our sql database (I know).

The only thing I coudl think of from your suite of products was a combobox, since the fileexplorer doesn't have checkboxes or the ability to select files from within the explorer window and upload them all at once.

Is there anyway I can populate th ecombobox with files from a folder? This way they'd be able to select them with the checkboxes and I could handle the sql upload in codebehind. If this isn't possible or more work than it's worth (which i think it is) please let me know.

Adding an extra value to a GridDropDownColumn

Hi, I have an editable grid where one of the fields uses a GridDropDownColumn to select the data, and is currently being populated using an SqlDataSource object. I would like to be able to add one additional item to the dropdown list to allow the user to select "nothing". Is there a way to do this? I know that I could add a blank value in my stored procedure but I would prefer not to do it that way if possible.

I'm also willing to populate my drop down field differently if need be. In fact, I do have instances where I will want to build the list of items from scratch in code, so if you could provide code to do this that would be a great help as well!

Here is the ASP code for the grid. It's the GLFundingID column that I want to add an item to.

<telerik:RadGrid ID="FundingFeesGrid" runat="server" Skin="Sunset" AutoGenerateColumns="false" AllowPaging="false" OnDeleteCommand="FundingFeesGrid_DeleteCommand" OnDetailTableDataBind="FundingFeesGrid_DetailTableDataBind" OnInsertCommand="FundingFeesGrid_InsertCommand" OnItemDataBound="FundingFeesGrid_ItemDataBound" OnNeedDataSource="FundingFeesGrid_NeedDataSource" OnUpdateCommand="FundingFeesGrid_UpdateCommand" OnItemCreated="FundingFeesGrid_ItemCreated">

<MasterTableView EditMode="InPlace" CommandItemDisplay="Top">

<Columns>

<telerik:GridBoundColumn DataField="GLFundingFeeID" Visible="false" />

<telerik:GridDropDownColumn DataField="GLFundingID" HeaderText="Funding Type" DataSourceID="FundingList" ListTextField="TypeName" ListValueField="GLFundingID" />

<telerik:GridBoundColumn DataField="FeeName" />

<telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn" HeaderText="Edit" HeaderStyle-Width="60px" HeaderStyle-HorizontalAlign="Center" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

Grid Context Menu - OnSortCommand

Hi,

We have a grid with CustomPaging, with 10 records per page. Sorting functionality is working fine when clicking on HeaderText. We are using OnSortCommand event to get sorted field and order as below.

FieldName = e.SortExpression, SortOrder = e.NewSortOrder

We also have context menu on the screen. When using ordering from ContextMenu SordCommand Event is not firing.

Do we need to explicitly attach event handler to any ContextMenu event?

RadButton Inside a RadSplitter with Scrollbar

I have a RadButton which is sitting in a user control in a RadPane. When the content in the pane grows too large, a vertical scrollbar appears. However, when the pane is scrolled, the button does not scroll with the rest of the content (as if it is positioned absolutely), whether it is in a table cell or a div. If I mouseOver the button after scrolling, it jumps back to its original position.

Using a "standard" button with a primary icon and no text in IE7.

Thanks.

Unknown server tag telerik:RadButton

I went through the upgrade wizard, but when I rebuild and go back to the wizard, it tells me that the currently used RadControls version is 2010.2.713.40 and suggests that I upgrade to 2010.2.929.40. When I click Get Latest Version, it says nothing newer found.

I upgrade to 2010.2.929.40 successfully. Then the wizard says I'm on 2010.2.290.40 (yay!) and that 2010.3.1109.40 is available (yay!) so I upgrade to it (just click next a few times), again it seems successful and the upgrade wizard now shows that I'm running 2010.3.1009.40 (yay!). I've done this process three times now.

Here's where it gets interesting: I have a RadButton that I coded directly in Source view. The error list shows no issues. I rebuild. Boom: error (as listed in title). Go to the upgrade wizard and oops, I'm back on 2010.2.713.40.

RadUpload and RadWindow on the same page

Telerik,

My team and I have been trying to decipher this paradox for a couple of days now, but unfortunately, all our efforts have ended being futile. I have RadUpload and RadWindow on the same ASPX page. The screen or logic flow is as follows:

User selects multiple images, using RadUpload
User clicks on preview button
Onclick event is captured in code-behind file; uploaded images are saved in session; javascript is injected, using RadAjaxManager; and RadWindow is triggered, which ultimately shows all the uploaded images.

We are also disabling AJAX for RadAjaxPanel and RadAjaxManager in order for RadUpload to have a full post-back. One thing we have noticed that if we do not disable the AJAX for the preview button, everything works as expected. This behavior, however, forces the RadUpload.UploadedFiles property to show zero count - even though several files are uploaded to the control.

We were using 2010.2.713.35 version of Telerik.Web.UI assembly, and decided to update to 2010.2.929.35 build, which is latest build. The updates, however, did not solve the problem.

We will be anxiously waiting to hear back from you.

The default page is as follows:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
