I have been able to get the parent child to work using the DetailTableDataBind event and having HierarchyLoadMode="Client". I am moving from Infragistics and using there controls I was able to bind the grid to a dataset that contained two tables with a data relationship defined using this method: Dim dr As DataRelation = New DataRelation("OrderTable", dc1, dc2, False) . How or can I do this for a RadGrid wihout using the DetaiTableDataBind event?

Thanks

Radgrid - Drag-n-drop - e.HtmlElement

Hi,

I am using the grid's built in drag and drop functionality and have observed a strange issue.
When dropping a grid item onto a html control within the grid, the "e.HtmlElement" is empty. It is only not empty when dropping on items outside of the grid. Is there any way around this? I would really like to be able to drop a grid item onto a specific row to trigger some functionality.

Thank you

RadGrid Virtual Scrolling with fixed height

Hi,

I am new to Telrik and using RadGrid with Virtual Scrolling feature.
When I scroll down, last page of Grid is selected automatically, it happens when there is some empty space below the records in Grid. I can not fix the height of Grid for some reason.

Has anybody faced this issue before. Please help me in resolving this issue.
Below is the Code used for virtual scrolling:

<telerik:RadGrid ID="radGridItem" AllowPaging="True" runat="server" AutoGenerateColumns="False" PageSize="5"

<MasterTableView TableLayout="Fixed">
<PagerTemplate>
<asp:Panel ID="PagerPanel" Style="padding: 6px; line-height: 24px" runat="server">
<div style="margin: 0px; float: right;">
Displaying page
<%# (int)DataBinder.Eval(Container, "Paging.CurrentPageIndex") + 1 %>of
<%# DataBinder.Eval(Container, "Paging.PageCount")%>
, items
<%# (int)DataBinder.Eval(Container, "Paging.FirstIndexInPage") + 1 %>
to
<%# (int)DataBinder.Eval(Container, "Paging.LastIndexInPage") + 1 %>
of
<%# DataBinder.Eval(Container, "Paging.DataSourceCount")%>
</div>
<div style="width:260px; margin: 0px; padding: 0px; float: left; margin-right: 10px; white-space: nowrap;">
<asp:LinkButton ID="Button1" runat="server" OnClientClick="changePage('first'); return false;"

<span style="vertical-align: middle;">Page:</span>
<telerik:RadNumericTextBox ID="RadNumericTextBox1" Width="25px"
Value='<%# (int)DataBinder.Eval(Container, "Paging.CurrentPageIndex") + 1 %>'
runat="server">
<ClientEvents OnValueChanged="RadNumericTextBox1_ValueChanged" />
<NumberFormat DecimalDigits="0" />
</telerik:RadNumericTextBox>
<span style="vertical-align: middle;">of

Rad Calendar and Rad Combo box .NET Master Pages

I am using RAD Controls for AJAX Q2 2009 SP1 with master pages in VS 2005 VB.NET.

The RAD Menu is located in the master page; the RAD AJAX manager is also located in the master page.

The content page contains two RAD Calendar controls and a RAD combo box. Everything is working in the page except for the RAD Combo box. If I have the RAD Combo box on the page without the calendar, it works fine; but just says "loading" when all controls are present.

We are transitioning to a new version of our Intranet that utilizes master pages; our previous version did not use master pages and these controls did not conflict with one another. Please advise.

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
