Error in RadGrid Export to Excel

I have a Radgrid that uses an objectdatasource which is configured this way

<asp:ObjectDataSource runat="server" ID="reportObjectDataSource" SelectMethod="GetInfo"

EnableViewState="false" TypeName="XXXX.ReportObjectDataSource"

onselecting="reportObjectDataSource_Selecting">

<SelectParameters>

<asp:FormParameter DbType="DateTimeOffset"

DefaultValue="" FormField="timeFrom" Name="frDate" />

<asp:FormParameter DbType="DateTimeOffset"

DefaultValue="" FormField="timeTo" Name="tDate" />

<asp:FormParameter DbType="Boolean"

DefaultValue="" FormField="btnAllVer" Name="allVer" />

</SelectParameters>

</asp:ObjectDataSource>

The Radgrid is declared in the designer of the page with this code:

<telerik:RadGrid ID="gridReport" runat="server" GridLines="None"

Skin="WebBlue" Width="700px" HeaderStyle-HorizontalAlign="Center"

AllowSorting="True" AllowPaging="true" PageSize="50">

<MasterTableView AutoGenerateColumns="True">

<CommandItemSettings ShowExportToExcelButton="true"></CommandItemSettings>

</MasterTableView>

<ClientSettings>

<Scrolling AllowScroll="true" SaveScrollPosition="true" UseStaticHeaders="true" />

</ClientSettings>

</telerik:RadGrid>

I also added a button that will be used to export the datagrid once it is clicked. However, after generation of grid and clicking the export button the error: "RadGrid must be DataBound before exporting" is encountered. Here's the code behind for the page:

protected void btnGenerate_Click(object sender, EventArgs e)

{

gridReport.DataSourceID = "reportAdhocObjectDataSource";

}

protected void btnExport_Click(object sender, EventArgs e)

{

gridReport.ExportSettings.FileName = "Report as of" + DateTime.Today.ToString();

gridReport.ExportSettings.ExportOnlyData = false;

gridReport.ExportSettings.IgnorePaging = true;

gridReport.ExportSettings.OpenInNewWindow = true;

gridReport.MasterTableView.ExportToExcel();

}

protected void reportObjectDataSource_Selecting(object sender, System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs e)

{

DateTime timeFr = timeFrom.SelectedDate.Value;

DateTimeOffset tFrom = timeFr;

e.InputParameters["frDate"] = tFrom;

DateTime timeT = timeTo.SelectedDate.Value;

DateTimeOffset tTo = timeT;

e.InputParameters["tDate"] = tTo;

e.InputParameters["allVer"] = this.btnAllVer.Checked;

}

This is urgent, so please, any help will be appreciated.

thanks

RadContextMenu and radwindows not working in sharepoint

Hi everybody,

I need solution very badly and very very quickly,

I used radcontrols in my dotnet application, those are working fine, But i placed same page in sharepoint webpart those are not working.

My senario is, i used RadGrid, RadButtons, RadWindows, RadMenuContext and other controls in my application, those are working fine. after that i had taken this page and placed in my sharepoint site and also taken dll of that page in "bin" folder of my site. Finally i had taken changes of web.config file form telerik site.

I had taken pageviewerWebpart and placed my page in that webpart, but HierarchicalGrid woriking fine but ContextMenu not comming. And radwinds not working. I got the error "Sys is Undefine".

function RowContextMenu(sender, eventArgs) {

//alert("RowContextMenu Method");

var menu;

var ownerTable = eventArgs.get_tableView();

if (ownerTable.get_name() == "DELIVERYDETAILS") {

menu = $find("<%= RadMenu1.ClientID %>");

}

else if (ownerTable.get_name() == "TASKS") {

menu = $find("<%= RadMenu2.ClientID %>");

}

document.getElementById("radGridClickedRowIndex").value = eventArgs.get_itemIndexHierarchical();

document.getElementById("radGridClickedTableId").value = ownerTable._data.UniqueID;

menu.show(eventArgs.get_domEvent());

}

The above code i used for ContextMenu.

function OpenWindowAddNewTask() {

Sys.Application.add_load(addNewTaskWindow);

}

function addNewTaskWindow() {

var WSID = document.getElementById("hidWSID").value;

var url = "AddNewTask.aspx?WS_ID=" + WSID + "&TaskID=0";

var oWnd = radopen(url, 'RadWindow1');

Sys.Application.remove_load(addNewTaskWindow);

}

Above code i used to open radwindow.

Those two are working fine in my dotnet application, but not sharepoint site.

Please give me the quick solution.

<asp:Label> controls within a <Telerik:PageView> control do not generate any local resource strings

Hi,

I have several pages containing multiple Telerik:Pageview controls on them and we need to implement globalization. When I click the Generate Local Resource File oiption from the Tools Menue in VS2008 I get a resx file generated and it has the RadTab labels and other controls represented in the resultant resx file, but not a single <asp:Label> control which is contained within a Telerik:PageView control is in the resx file.

Any Ideas anyone?

It would really be unfortunate if for some reason things inside a Telerik:Pageview control were not able to generate the metadata tags for globalization.

Thanks,

Gary
