I get following error :

Specified argument was out of the range of valid values. 

When I read RadNumericTextBox like this 

 RadNumericTextBox numTextBox = (RadNumericTextBox)editItem["TextCol1"].Controls[0];

Issue is not occuring When I use old Telrik UI Dll. (2010)

It occurs only with latest dll (2014)

Please let us know How to read with the latest dll?

Best Regards,

Here is my code snap.

We are experiencing an issue where, when right clicking on a file in the RadFileExplorer, the file is sometimes deleted immediately. No confirmation dialog is displayed, as is usually the case when deleting files.

It only seems to happen in Safari and seems to happen intermittently. We have reproduced it on both Mac and Windows platforms.

I'm just wondering if this has been reported before or if you have any suggestions.

Any help you can offer will be appreciated.

Thanks

We have several pages where we have successfully exported RadGrid contents to Excel using the ExportToExcel() method.  However, we now have a situation where we have a multi-page wizard using a MultiView controls and one of the View controls has a RadGrid on it with a preview of some results.  The users would like to be able to export this RadGrid to Excel.  However, the typical code does not work:

        protected void ExportToExcelButton_Click(object sender, EventArgs e)
        {
            PreviewGrid.ExportSettings.IgnorePaging = true;
            PreviewGrid.ExportSettings.OpenInNewWindow = true;
            PreviewGrid.MasterTableView.ExportToExcel();
        }

The RadGrid is fairly simple:

<telerik:RadGrid ID="PreviewGrid" AutoGenerateColumns="False" 
                    OnNeedDataSource="PreviewGrid_NeedDataSource" 
                    runat="server" Width="730px" Height="362px">
    <ClientSettings>
        <Selecting EnableDragToSelectRows="false"/>
        <Scrolling AllowScroll="true" UseStaticHeaders="True"></Scrolling>
    </ClientSettings>
    <MasterTableView DataKeyNames="Key" NoMasterRecordsText="Nothing would be generated." CommandItemDisplay="Top" >
        <CommandItemTemplate>
            <div class="floatRightDiv" style="margin-top: 3px;margin-left: 700px;display:none;">
                <asp:Button ID="ExportToExcelButton" runat="server" CssClass="rgExpXLS" OnClick="ExportToExcelButton_Click" Visible="false"/>
            </div>
        </CommandItemTemplate>  
        <Columns>
            <telerik:GridBoundColumn UniqueName="Field1" DataField="Field1" HeaderText="Field1"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn UniqueName="Field2" DataField="Field2" HeaderText="Field2"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn UniqueName="Field3" DataField="Field3" HeaderText="Field3"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn UniqueName="Field4" DataField="Field4" HeaderText="Field4"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn UniqueName="Field5" DataField="Field5" HeaderText="Field5"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn UniqueName="Amount" DataField="Amount" HeaderText="Amount" DataFormatString="{0:N2}" ItemStyle-HorizontalAlign="Right" HeaderStyle-HorizontalAlign="Right"></telerik:GridBoundColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

I'm having issues with the rad editor buttons overlapping at smaller window sizes.  In attached image, look at the buttons to the right of the "Aa" button.  Code is below.

                                            <telerik:RadEditor ID="rtbBannerHtml" runat="server" 
                                                Skin="Silk"
                                                ToolbarMode="Default"
                                                Height="300px" 
                                                Width="100%" 
                                                ToolsFile="/ets/radcontrols/Editor/config/AdvancedBaseTools.xml"
                                                ShowSubmitCancelButtons="false">
                                            </telerik:RadEditor>

We have recently upgraded the telerik controls from v2010.2.1029.35 to v2014.3.1209.35. With old version, when we paste the HTML content shown below in the 'HTML' mode and then switch to the 'Design' mode, the editor removes the duplicate 'HEAD', 'TITLE', 'BODY' tags automatically. But when the same thing is done with the upgraded  one, the editor removes all the content  with the duplicate tags except the last one.

Any suggestion why it is behaving differently? Thanks in advance for the suggestions.
