On an export to Excel, I can't seem to find a way to suppress the header row. I'm creating the grid programmatically. Here's the relevant code:

RadGrid

exportGrid = new RadGrid();

exportGrid.NeedDataSource +=

new GridNeedDataSourceEventHandler( exportGrid_NeedDataSource );

exportGrid.Skin =

"Default";
exportGrid.Width = Unit.Percentage( 100 );
exportGrid.ShowHeader = false;
exportGrid.AutoGenerateColumns = true;
exportGrid.ExportSettings.ExportOnlyData = true;
exportGrid.ExportSettings.Excel.Format = GridExcelExportFormat.ExcelML;
exportGrid.DataMember = "ExportData";
PlaceHolder phExport = new PlaceHolder();
currentPage.Controls.Add( phExport );
exportGrid.DataSource = _exportData;
phExport.Controls.Add( exportGrid );
exportGrid.Rebind();

foreach ( GridHeaderItem headerItem in exportGrid.MasterTableView.GetItems( GridItemType.Header ) )
headerItem.Visible = false;

exportGrid.MasterTableView.ExportToExcel();

I also tried a couple of different variations on this approach, without any luck:

protected

void exportGrid_ExcelMLExportRowCreated( object source, Telerik.Web.UI.GridExcelBuilder.GridExportExcelMLRowCreatedArgs e ){
if ( e.RowType == Telerik.Web.UI.GridExcelBuilder.GridExportExcelMLRowType.HeaderRow ){
foreach ( Telerik.Web.UI.GridExcelBuilder.CellElement cell in e.Row.Cells ){
if( cell.Data != null )
cell.Data.DataItem = null;
}
}
}

Any help is appreciated.

Add a button to multiple grids programmatically

I have a project with many, many grids. I want to add a clear all filters button to every grid in my project. I have a clear all method that works beautifully, but I can't seem to add a button with a successful event handler to all my grids without manually going through and adding the button. I would like it somewhere at the top of my grid. Any help would be appreciated.

originalPath, originalAttribute inserted into javascript code in IE

Here's the sample code I'm using:

</noscript>

When I add the code to the HTML mode, then switch to the Design Mode, then switch back to the HTML mode,
1) the <script> tags disappear, and
2) the <noscript> tags have inserted "originalAttribute=X" and "originalPath=Y" into the anchor tags.

In IE only (I'm using IE 8), both 1 and 2 can be reproduced by pasting the sample code above into the Editor Demo: http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx.

Thanks.

Server side button onclick does not trigger with RadAjaxManager

I am using several settings in RadAjaxManager. I have a server control asp button which re-loads the whole page when clicked. To prevent that I put this setting in RadAjaxManager

<telerik:AjaxSetting AjaxControlID="btnPrint">

</UpdatedControls></telerik:AjaxSetting>

but for some reason my code behind click event does not fire. Any ideas please

<asp:Button ID="btnPrint" runat="server" Text="Print" CssClass="button" OnClick="btnPrint_Click" ></asp:Button>

Inline editing, scroll mouse wheel.

Hi, I have a question. When I do inline editing: I have a number of columns with integers. When I want to inline edit a column it works perfect.

However, I notice that when I "in" a cell and I use my mouse wheel the value goes up or down.

I don't want that tp happen because it can confuse people.

How to prevent this?
