Safari bug?

We have a user using Safari 3.1 (on Mac OS X 10.4) who reports that when he clicks on the RadComboBox nothing happens. The combobox doesn't drop down as it should. Are there any known issues with RadComboBox and Mac Safari? I am running the latest version of Prometheus on the website. Here is the RadComboBox in my aspx page:

<

telerik:RadComboBox ID="rcbProcessGroup" DataSourceID="dsGetProcessGroups" runat="server" Skin="WebBlue" AppendDataBoundItems="true" Font-Size="12px" AutoPostBack="true" DataTextField="ProcGroupName" DataValueField="PgrpID" Width="196px">
<Items>
<telerik:RadComboBoxItem runat="server" Text="All Processes" Value="0" />
</Items>
</telerik:RadComboBox>

Grid doesn't fit viewport

Hi All

We have a radgrid with has several columns, that when viewed on a mobile device is too wide for the viewport. This is simply because of the number of columns.

We are using Bootstrap and the page is responding correctly.

Before I code it to hide columns on smaller devices, has anyone had this problem before? and what is the fix? Can you get the grid to scale for example?

ExportToExcel does not returns anything/does not work

While I read many posts about this issue, none seem to fit my particular problem.

I have a very simple web form, with a grid, which is not ajaxified, in server side code, I call a complex object that returns a simple list of items as a datatable and set it as datasource for my grid. The grids works and displays all OK, however when I try to export to xlsx (and actually any supported format), nothing happens after calling MasterTableView.ExportToExcel().

I did verified that the grdWarranties items is not empty and that the datasource is not lost. Below substract of the web page and the server side code to execute the export:

Protected Sub btnExport_Click(sender As Object, e As Telerik.Web.UI.ImageButtonClickEventArgs) Handles btnExport.Click

grdWarranties.Page.Response.ClearHeaders()

grdWarranties.Page.Response.Cache.SetCacheability(HttpCacheability.Private)

grdWarranties.ExportSettings.Excel.Format = Telerik.Web.UI.GridExcelExportFormat.Xlsx

grdWarranties.ExportSettings.IgnorePaging = False

grdWarranties.ExportSettings.ExportOnlyData = True

grdWarranties.ExportSettings.OpenInNewWindow = True

grdWarranties.MasterTableView.ExportToExcel()

End Sub

<asp:Panel runat="server">

<table class="WarrantyCheckTable" style="margin-top:15px">

<tr>

<td style="width:15%">

<telerik:RadLabel ID="RadLabel1" Text="Type or paste in your Landis+Gyr serial numbers:" runat="server" Font-Size="Small" Font-Italic="True"></telerik:RadLabel>

<telerik:RadTextBox ID="txtMSNs" runat="server" TextMode="MultiLine" BorderColor="#7AB800" BorderWidth="1px" Height="93%" Width="100%" Wrap="False" ></telerik:RadTextBox>

<td style="width:5%">

<td >

<telerik:RadGrid ID="grdWarranties" runat="server" AllowSorting="True" AutoGenerateColumns="False" ShowGroupPanel="True" Width="100%" ViewStateMode="Enabled" RenderMode="Lightweight" >

<ExportSettings ExportOnlyData="True" FileName="WarrantyData" OpenInNewWindow="True">
