Please help.

I receive the following error when adding an exception to the recurrence:

I'm kind of surprised that Telerik has not come out with a server-side animation control, like the existing AjaxControlToolkit's Animation Extender (but more functional and easier to implement). There are other alternatives, like RIAnimation (http://www.hushhushmedia.com/page/RIAnimation.aspx) but that is clearly no longer supported. This would be for those of us who want high quality jquery animations, but don't want to bother with javascript!

Hi,

Is it possible to control what appears in the "Files of type" combo in the "Choose file to upload" dialog?
If I want to upload just .xyz files then I possible want just .xyz to appear in the "Files of type" combo.
But I guess it's not possible?

Regards,
Peter

Hello,
         I have a RadAsyncUpload control inside UpdatePanel(AJAX). When I upload the file, the upload never completes. I tried with the latest 2010 version. I still cant upload the file when RadAsyncUpload is insde the UpdatePanel. If I remove the UpdatePanel, then I m able to upload the file, but the entire screen refreshes, which is what I want to avoid.


Thanks,
Bharani

There are several examples to enable Dynamic Data support on a gridview without using the full Dynamic Data scaffolding (global.asax + dynamicdata folder) such as on this video

I followed along with the example as shown in the video and I was able to get gridview to work correctly with dynamic support.

However, the same steps do not work with DynamicRadGrid. I get the error:

Here are steps I took:
1. In the Page_Init:

RadGrid1.EnableDynamicData(typeof(Plan));

2. Made a MetaData Class:

[MetadataType(typeof(PlanMD))]

    public partial class Plan

    {

        public class PlanMD

        {

            [StringLength(50), Required]

            public string Name { get; set; }

        }

    }

3. Added a validation summry on the page
4. Add a dynamicradgrid on the page with DynamicColumn

<dynamic:DynamicRadGrid ID="RadGrid1" runat="server" AllowAutomaticInserts="True"

            AllowAutomaticUpdates="True" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False"

            AutoGenerateDeleteColumn="True" AutoGenerateEditColumn="True" DataSourceID="EntityDataSource1"

            GridLines="None">

            <MasterTableView AllowAutomaticInserts="False" CommandItemDisplay="Top" DataKeyNames="Id"

                DataSourceID="EntityDataSource1">

                <CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>

                <RowIndicatorColumn>

                    <HeaderStyle Width="20px"></HeaderStyle>

                </RowIndicatorColumn>

                <ExpandCollapseColumn>

                    <HeaderStyle Width="20px"></HeaderStyle>

                </ExpandCollapseColumn>

                <Columns>

                    <dynamic:DynamicGridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name">

                    </dynamic:DynamicGridBoundColumn>

  

                </Columns>

            </MasterTableView>

        </dynamic:DynamicRadGrid>

Please advise if DynamicRadgrid is even designed to work in this scenario. Thanks

Hello, having some issues with having a TextBox in an ItemTemplate.

First it was the text box not accepting "space" but i found the workaround in the forums.
http://www.telerik.com/help/aspnet-ajax/listbox-space-ignored-textbox-itemtemplate.html

Now, typing text into the textboxes creates unwanted behavior when using the "s" character. The behavior im seeing is when typing the "s" charater in the RadListBoxItem.Textbox the selection attempts a changes to the next visible list box item. the focus bounces back and forth between the visible items (I only have 2 items visible at any given time due to size contraints.). I've looked high and low on a way to disable the listbox keyboard shortcuts but found nothing.

Im unsure how many other keyboard shortcuts are associated with this control, but since i need a textbox (well, a couple) I'd like to simply turn off keyboard support for this control.

Heres the markup:

 

<telerik:RadListBox runat="server" ID="listBoxSlideShowActiveItems" 

    SelectionMode="Multiple" EnableDragAndDrop="true" 

    AllowDelete="false" AllowReorder="true" Height="200px" Width="370px" AllowTransferOnDoubleClick="false">

    <ItemTemplate>  

        <fieldset>

            <legend style="font-size:8pt;padding-bottom:2px;">Slide Description</legend>

            <table border="0" width="100%">

                <tr>

                    <td style="width:80px;" valign="top">

                        <asp:Image ID="imageActiveItemThumbnail" runat="server" CssClass="thumbnailImageSlideShowLarge" ImageUrl="~/SiteImages/spacer.gif" />

                    </td>

                    <td valign="top">

                        <table border="0" width="100%">

                            <tr>

                                <td>Text:</td>

                                <td><asp:TextBox ID="textActiveItemText" runat="server" Width="170"></asp:TextBox></td>

                            </tr>

                            <tr>

                                <td>Href</td>

                                <td><asp:TextBox ID="textActiveItemHref" runat="server" Width="170"></asp:TextBox></td>

                            </tr>

                            <tr>

                                <td>Target:</td>

                                <td>

                                    <telerik:RadComboBox ID="comboActiveItemTarget" runat="server" Width="178px">

                                        <Items>

                                            <telerik:RadComboBoxItem Text="_blank" Value="_blank" Selected="True" />

                                            <telerik:RadComboBoxItem Text="_parent" Value="_parent" />

                                            <telerik:RadComboBoxItem Text="_search" Value="_search" />

                                            <telerik:RadComboBoxItem Text="_self" Value="_self" />

                                            <telerik:RadComboBoxItem Text="_top" Value="_top" />

                                        </Items>

                                    </telerik:RadComboBox>

                                </td>

                            </tr>

                        </table>

                    </td>

                </tr>

            </table>

        </fieldset>

    </ItemTemplate>

    <Items></Items>

</telerik:RadListBox>

<script type="text/javascript">

    // RadListBox documented workaround for textbox in item template

    // http://www.telerik.com/help/aspnet-ajax/listbox-space-ignored-textbox-itemtemplate.html

  

    var radListBoxKeyDown = Telerik.Web.UI.RadListBox.prototype._onKeyDown;

    Telerik.Web.UI.RadListBox.prototype._onKeyDown = function (e) {

        if (e.keyCode == Sys.UI.Key.space) {

            return;

        }

        else {

            radListBoxKeyDown.apply(this, arguments);

        }

    }

Thanks in advance!

Hi,

    I use RadEditor inside ModalpopUpExtender in our Project.. I use ImageManager Tool in RadEditor.. When i click on the Image Manager tool, its dialog window gets opened behind Rad Editor.. Please Guide me..

Why is there an ItemInsert event and an ItemCommand event? Why not case out all the CRUD events in the ItemCommand event? Does it have something to do with having AllowAutomaticInserts turned on?

Are these events where I should get the values from my EditFormTemplate controls and assign them to the Update/Delete/Insert parameters of my ObjectDataSource?

I'm a newbie, obviously. Sorry for all the questions at once.

I need to be able to select the null value to a RadComboBox bind to an EntityDataSource,

in WPF there is a ClearSelectionButtonVisibility, what is the alternative in ASP.NET AJAX? without doing it manually

thanks in advance
