Hi,

When I try to upload a png image with the radeditor image manager, it always fails.
It doesn't show an error, but the uploaded file is 0kb.
The filetype is allowed (File extensions allowed:*.jpg, *.jpeg, *.png, *.bmp, *.gif)
It only happens with png.

What could be wrong?

Tnx.

RadGrid default pagination option disappears

Hi everyone,

Anyone noticed that when you hard code a pagination size (in the code behind) for a radgrid widget the default page size that appears in the drop-down (mine has options 10, 15, 20 and 50, with 15 as default) disappears?
Has anyone else noticed this?

Example:

I have options 10, 15, 20 and 50. 15 is default. They all appear.

However when I set say (in the code behind): RadGrid1.Pagesize = 50;

what now happens is that I see (when I run the code) the following options: 10, 20 and 50. i.e. 15 has disappeared!

Ques: Is this a bug??

"Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method" when filter or order GridTemplateColumns

Hi,

I have a problem when i try to filter or group by any column of GridTemplateColumn Type, with anyother type there is no problem.
ther specific exception is: Microsoft JScript runtime error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.
(Exception Screenshot is attached)

The declaration for the specific column is:

<telerik:GridTemplateColumn HeaderText="GMT" SortExpression="GMT" UniqueName="GMT" >

<HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" />

<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />

<ItemTemplate>

<asp:Label runat="server" ID="lblGMT" Text='<%# Bind("GMT") %>'></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<br />

<telerik:RadNumericTextBox runat="server" Width="100px" ID="txtGMT"

Text='<%# Bind("GMT") %>'  DataType="System.Int16" MaxValue="12" MinValue="-12" NumberFormat-DecimalDigits="0" ShowSpinButtons="true" />

<span style="color: Red">*</span><br />

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="txtGMT"

ErrorMessage="This field is required" runat="server" Display="Dynamic">

</asp:RequiredFieldValidator>

</EditItemTemplate>

</telerik:GridTemplateColumn>

The scenario:
I have a MutliView and tabstrips. I have a PageView that contains a combobox and a Radgrid, all with RadAjaxManagerProxy with a MasterPage. The combobox updates the RadGrid, everything works fine just when i try to filter or group by those kind of columns the app crushes with the exception.

I hope you can help me.

Best Regards.
-Luis

RadAjaxLoadingPanel not working on refresh

I have two pages that use a RadAjaxLoadingPanel for a smooth refresh of a RadGrid. In each case, the RadGrid uses an ASP.NET ObjectDataSource to load data, and the object data source handles all paging, sorting, and filtering. The RadGrids enable multicolumn sorting and column reordering. Both pages use an ASP.NET timer for periodic refresh.

One page works perfectly; the page refresh is limited to the grid, for timer, paging, sorting, and column ordering. The loading panel shows during refresh, and the refresh is smooth. On the other page, the loading panel never shows. In the VS development server, the refreshes are usually limited to the grid (not always); however in IIS, I always get a full-page reload instread of a refresh, for all events (timer, paging, sorting, column reorder).

Environment: Windows 7 x64, VS 2010, IIS 7, Telerik ASP.NET Ajax Q2 2010 SP2.

Here is the markup for the loading panel on the page that fails. The page that works is essentially identical except that there are no scripts or services referrenced inside the radScriptManager.

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

<Scripts>

<asp:ScriptReference Path="~/JavaScript/SynapseStudyCache.js" />

</Scripts>

<Services>

<asp:ServiceReference Path="~/WebServices/Synapse/Caching.asmx" />

</Services>

</telerik:RadScriptManager>

<telerik:RadAjaxLoadingPanel ID="RadiologistWorklistLoadingPanel" runat="server" InitialDelayTime="0" MinDisplayTime="300" />

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Timer1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rdWorkList" LoadingPanelID="RadiologistWorklistLoadingPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="rdWorkList">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rdWorkList" LoadingPanelID="RadiologistWorklistLoadingPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

There are no javascript references to either the loading panel or the RadGrid, and the code-behind handles only the ItemDataBound event for the grid. The code-behind handles Timer1.Tick but does nothing with it.

Any suggestions on why the page does not refresh properly?

AsyncUpload + Ajax processing + .UploadedFiles property

Hi all,

I'm using AsyncUpload with RadAjaxManager and RadBinaryImage to upload images, and preview them immediately in the page, before the Page Postback. This works fine, the preview works very well; I used the exact same setup as is shown in the "Ajax processing" sample.

However, I'd like to know which file was uploaded, when my page is posted back properly by the user. Unfortunately, the AsyncUpload1.UploadedFiles collection is empty. If I disable the RadAjaxManager.ajaxRequest() call (thereby disabling the preview), the UploadedFiles collection does work.

Is there a way to let these techniques work together? How can I retain info about the uploaded files until postback?

Thanks for any info.

I have the above code which renders fine in IE8 and FF 3.x but in IE 6 and 7 (compatibility mode) it is not rendered correctly. I even tried specifying a Height and Width along with AutoSize="true".

Please help!

Find all calendar/time popups

I have tried to get this working for the 2009 release, but I am having no luck.

http://www.telerik.com/community/forums/aspnet/calendar/popup-calendar-does-not-close-when-clicking-on-scrollbars.aspx

What I need to be able to do is close all (telerik) datepicker, timepicker, colorpicker, combo popup windows when I scroll, as I do not know the name of these controls at design time as they are dynamically loaded I need some way of getting them all.

Combo is easy as there is an array

        function closeCombos() {
            for (i = 0; i < Telerik.Web.UI.RadComboBox.ComboBoxes.length; ++i) {
                Telerik.Web.UI.RadComboBox.ComboBoxes[i].hideDropDown();
            }
        }
