Radgrid Export after auto filter issue

I am having an issue when attempting to export a radgrid to excel after utilizing the filters in the auto filter.

Before applying the filter, it works perfectly and exports the data to excel. After applying the filter, the export does not work and appears to simply rebind the grid; however this time the filter rows are removed.

The data for the grid is populated using the NeedDataSource event.

Through searching the forums, I have found that I should probably be using the ExcelML, but this yields the same results.

protected void radimgbtnExcelExport_Click(object sender, ImageButtonClickEventArgs e)

{

radgridUsageRatio.ExportSettings.Excel.Format = GridExcelExportFormat.ExcelML;

radgridUsageRatio.ExportSettings.IgnorePaging = true;

radgridUsageRatio.ExportSettings.ExportOnlyData = true;

radgridUsageRatio.ExportSettings.OpenInNewWindow = true;

radgridUsageRatio.MasterTableView.Columns[0].Visible = false; //remove command column

radgridUsageRatio.MasterTableView.Columns[1].Visible = false; //remove command column

radgridUsageRatio.MasterTableView.ExportToExcel();

}

Any help anyone can provide would be extremely helpful

Trying to impliment font awesome

I need to globally set a class on the combobox dropdown arrow

...but there's no public css property to do that right? There's one for the control, the dropdown list, the input, and the label....but no button.

So I'm looking for a skinnable property, not a workaround to inherit from he control or parse the dom with jquery, or do any codebehind. There's too many comobs to just go around updating all the code in every page (hoping to just leverage a .skin file)

Yes, no?...could you add one?

RadNumericTextBox in iPad

Hello

Using RadNumericTextBox in a mobile website doesn't pop up numeric keyboard in iPad. We're developing a website where the user has to enter a lot of numeric information and it has to choose the numeric pad each time it enters a new numeric field.

I know that using RadTextBox and Inputtype solves this problem, but I mainly use RadNumericTextBox because it allows to specified validation like min and max values to each field.

Thanks in advanced

I'm using the following AccessDataSource

<asp:AccessDataSource ID="AccessDataSource2" runat="server"

CacheDuration="300"

DataFile="\\servername\myfile.mdb"

SelectCommand="SELECT `CustomerNo`, `Company`, `Attention`, `City`, `State` FROM `Customers`" >

</asp:AccessDataSource>

for

<telerik:RadComboBox ID="ddlCustomers" runat="server"

Width="150px" Height="150px"

Skin="Vista"

DataSourceID = "AccessDataSource2"

DataTextField = "CustomerNo"

DataValueField = "CustomerNo"

DropDownWidth="410px"

EmptyMessage="Select a Customer"

EnableItemCaching="true"

EnableLoadOnDemand="true"

EnableVirtualScrolling="true"

HighlightTemplatedItems="true"

SelectedValue='<%# DataBinder.Eval(Container, "DataItem.CustomerName") %>'

AllowCustomText="true"

OnSelectedIndexChanged="ddlCustomers_OnSelectedIndexChanged" AutoPostBack="True"

>

<HeaderTemplate>

<table style="width: 400px" cellspacing="0" cellpadding="0">

<tr>

<td style="width: 100px;"> Customer No</td>

<td style="width: 150px;">Company Name</td>

<td style="width: 150px;">City</td>

</tr>

<tr>

<td style="width: 100px;"></td>

<td style="width: 150px;">Attention</td>

<td style="width: 150px;">State</td>

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="width: 400px" cellspacing="0" cellpadding="0">

<tr>

<td style="width: 100px;"><%# DataBinder.Eval(Container.DataItem, "CustomerNo")%></td>

<td style="width: 150px;"><%# DataBinder.Eval(Container.DataItem, "Company")%></td>

<td style="width: 150px;"><%# DataBinder.Eval(Container.DataItem, "City")%></td>

</tr>

<tr>

<td style="width: 100px;"></td>

<td style="width: 150px;"><%# DataBinder.Eval(Container.DataItem, "Attention")%></td>

<td style="width: 150px;"><%# DataBinder.Eval(Container.DataItem, "State")%></td>

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

and if that Access file not open, then its fine otherwise I can received this error "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Could not use ''; file already in use." I can open this Access file fine without any error when other is opening it.

Thanks
