Using User Control with Telerik Grid in Telerik Grid column

A Telerik grid (Sorting, Paging enabled) with edit, delete & insert (popup) commands is used inside a user control. This user control is used in a webpage (Telerik Grid's Template Field column). When tried to use user control's grid events (edit, delete, insert, sorting, paging ...), A Control is already associated with the element exception is thrown.

<asp:UpdatePanel ID="updatePanel1" runat="server">
    <ContentTemplate>
        <ucl1:FormsControl ID="FormsControl1" runat="server" />
    </ContentTemplate>

Problem with multiple Async Upload controls on a page

I have a user control that contains an Async upload control, a comments text box and a save button. The save button is the Async upload postbackTrigger. This user control has been added multiple times to a page. If a user uploads an image for each upload control and then clicks a save button for any of the upload controls, the server side FileUpload event triggers for all of the uploaded files, not just the upload control where the save button was clicked. How can I get the FileUpload event to trigger only once for the upload control where the save button was clicked? Attached is a screen shot of the form.

Thank You for your help.

Replaced Edit Form, Still Getting Mini Edit Form

I used the method described in the following article: Scheduler - External Edit in RadDock

The new edit form works perfectly. However, after the new edit form closes, I still have this little, tiny edit form that has no functionality. The buttons don't do anything on it. I want that tiny form to go away. Any ideas?

Thanks.

RadAjaxPanel disappears when using RadAjaxLoadingPanel

I have some simple processing going on inside a RadAjaxPanel, but when I add the RadAjaxLoadingPanel to get the spinner, the whole Panel just turns white / disappears until the postback returns.

This is a SharePoint Visual webpart and is now happening in two different projects (different site collections), regardless of what controls are inside the RadAjaxPanel.

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"></telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"></telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxPanel runat="server" LoadingPanelID="RadAjaxLoadingPanel1">

...Some postbacks

</telerik:RadAjaxPanel>

autopick autocomplete value in codebehind

I am trying to replicate my asp.net ajax control toolkit autocompletes with the telerik version of the autocomplete. I have everything working but one portion of it. I have the control set to select one item only and the control to postback. On text change I would like to populate the page with a users information from the value of the autocomplete box, but the text_changed event seems not to work for this control as I get no value in teh response.write

Protected Sub radAutoComplete_TextChanged(sender As Object, e As AutoCompleteTextEventArgs) Handles radAutoComplete.TextChanged

Dim value As String = radAutoComplete.Entries(0).Value

Response.Write(value)

Response.End()

End Sub

I do get a value if I attach to a linkbutton and do it this way, however then they have to pick on a button to produce results. Currently on my Ajax toolkit autocompltes it is able to show results on a text_changed event. So is there a way to do this with telerik autocomplete.

Protected Sub lnkView_Click(sender As Object, e As EventArgs) Handles lnkView.Click

Dim value As String = radAutoComplete.Entries(0).Value

Response.Write(value)

Response.End()

End Sub

Keep RadAjaxPanel visible while loading

I'm trying to achieve the same effect while loading a grid as the demos (e.g. http://demos.telerik.com/aspnet-ajax/ajax/examples/manager/partialajaxification/defaultcs.aspx). But when my grid is updating, the RadAjaxPanel is set to display:hidden while the RadAjaxLoadingPanel is displayed. I want the semi-transparent contents of the loading panel to be displayed on top of the grid, like the demo. How can I make the ajax panel contents remain visible?

Dont know hat kind of wierd styling this thing has but it will not allow anything inline with it. how can I put my linkbutton inline with the autocomplete. Even tried using a div but also no go.

<table style="width:100%">

<tr>

<td style="width:100%;text-align:center">

<telerik:RadAutoCompleteBox ID="radAutoComplete" runat="server" OnClientRequesting="requesting" EmptyMessage="Enter Users Last Name First Name."

InputType="Text" TextSettings-SelectionMode="Single">

<WebServiceSettings path="../AutoComplete.asmx" Method="UserAccounts" />

</telerik:RadAutoCompleteBox>

<asp:LinkButton ID="lnkView" runat="server" Text="ViewUser"></asp:LinkButton>

</td>

</tr>

</table>

<div class="CenterDiv">

<telerik:RadAutoCompleteBox ID="radAutoComplete" runat="server" OnClientRequesting="requesting" EmptyMessage="Enter Users Last Name First Name."

OnClientFileUploading question

Thanks all in advance.

We understand how the set_cancel method works within the OnClientFileUploading event. However, we need to confirm the behaviour when set_cancel(true) is executed. Does it cancel all the files in a multiple file upload or just the one file?

Also, we would like to do some custom validation within the OnClientFileUploading event but need to get the file extension in order to do this. We see how to issue args.get_fileName() but need to inspect the extension based on our own invalid extension list. Is there a file extension method available for this?

Thanks...Bob Baldwin
