Good afternoon, I believe we have a bug in the Rad Grid.

I have the following code to display a grid with a date field formatted a {0:d}. Being in Australia this begins correctly in d/MM/yyyy format, but as soon as you scroll (the scond click does it) the format changes to MM/dd/yyyy (american date format). Setting virtualization to false cures it. Setting the format explicitly cures it, but as we have an international application I don't want to do that. There are no OnScroll events on the page or server that I have added. Any ideas?

<telerik:RadGrid ID="dgSessions" runat="server"  AutoGenerateColumns="false"
            AllowSorting="true" GroupingEnabled="false" 
            EnableHeaderContextMenu="true" AllowPaging="true" PageSize="1000" OnNeedDataSource="dgSessions_NeedDataSource">
                
            <MasterTableView TableLayout="Auto">
                <Columns>
                     <telerik:GridDateTimeColumn UniqueName="SessionKey" HeaderText="" DataField="SessionKey" DataFormatString="<a target='_blank' href='SessionDetails.aspx?sessionkey={0}'>View</a>" ReadOnly="True" ShowSortIcon="False" ShowFilterIcon="False">
                    </telerik:GridDateTimeColumn>

                    <telerik:GridDateTimeColumn UniqueName="Date" HeaderText="Date" DataField="StartTime" DataFormatString="{0:d}" ReadOnly="True" >
                    </telerik:GridDateTimeColumn>

                    <telerik:GridBoundColumn UniqueName="StartTime" HeaderText="Start" DataField="StartTime" DataFormatString="{0:HH:mm}" ReadOnly="True" AllowFiltering="False" ShowSortIcon="False" ShowFilterIcon="False">
                    </telerik:GridBoundColumn>
                   
                </Columns>
            </MasterTableView>
            <ClientSettings ReorderColumnsOnClient="true" AllowColumnsReorder="true" ColumnsReorderMethod="Reorder">
                <Virtualization EnableVirtualization="True" InitiallyCachedItemsCount="20000"
                    LoadingPanelID="RadAjaxLoadingPanel1" ItemsPerView="20"/>
                <Scrolling AllowScroll="true" UseStaticHeaders="true" />
                <Resizing AllowColumnResize="True" EnableRealTimeResize="True" ResizeGridOnColumnResize="False" AllowResizeToFit="True"></Resizing>
                <ClientEvents OnGridCreated="GridCreated" />
            </ClientSettings>
            <PagerStyle Mode="NextPrevNumericAndAdvanced"></PagerStyle>

        </telerik:RadGrid>

I use a RadAutoCompleteBox with DataScouceID set inside an InsertItemTemplate of a RadGrid. When clicking on add-record button i got a 'DataSource not set' exception. I have to use the OnDataSourceSelect function to manually control the amount of data. It seems that the databounding has to be earlier. I tried to set the DataSource in the ItemCreate event on the RadGrid, and do not use the DataScouceID property. But in this case, I got an ReadOnlyDataSource in the OnDataSourceSelect event passed and the solution provided below does not work any more. 

Could you please tell me what to do in order to keep the function txtSciMapUser_DataSourceSelect as it is?

Thanks a lot.

Hi

I am a trying to export radgrid to excel.

My Export settings are as follows

<ExportSettings FileName="Reports" ExportOnlyData="true" IgnorePaging="true" OpenInNewWindow="true" Excel-Format="Html"></ExportSettings>

I am setting border below in 

protected void RadGrid1_HTMLExporting(object sender, GridHTMLExportingEventArgs e)
{
            e.Styles.Append("th { border:solid 0.1pt #CCCCCC; }");

}

I am able to export with border. But my Group Column was separated as 2 cell in output. 

I have attached 2 images (expected results vs error_output)

Please help!!!

I'm applying MailMerge example mentioned here in our system

I added code related to custom dropdown only, to test insertion

After selection an option, I just get a title window, like shown in screenshot_1.png attached
here's what shown in debugger, as shown in debugger.png attached. Reading values seems working fine, but the insertion itself doesn't happen, instead that message only shows.
