Group Header Totals

I know we can perform calculations and add them to a group header:

Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)

If TypeOf e.Item Is GridGroupHeaderItem Then

Dim item As GridGroupHeaderItem = CType(e.Item, GridGroupHeaderItem)

Dim groupDataRow As DataRowView = CType(e.Item.DataItem, DataRowView)

item.DataCell.Text = (item.DataCell.Text + "; Avg: ")

item.DataCell.Text = (item.DataCell.Text + (CType(groupDataRow("total"), Decimal) / Integer.Parse(groupDataRow("count").ToString)).ToString)

End If

End Sub

But is there a way to just add the Column aggregate:

<telerik:GridBoundColumn DataField="Subject" FilterControlAltText="Filter Subject column"

HeaderText="Subject" SortExpression="Subject" UniqueName="Subject" ItemStyle-HorizontalAlign="Left"

FooterStyle-HorizontalAlign="Left" FooterText="Tickets " Aggregate="Count">

</telerik:GridBoundColumn>

Thank you in advance.

Window title is empty

Hi

Updated radcontrols to the latest release and noticed an usual behavior with radwindow title. Before updating the window title is automatically set to the title of its content by default and in the new release the title is null if no value is specified. Is this an expected modification?

Thanks
Damian

[Solved] Custom Handler and temp folder.

Documentation states:

RadAsyncUpload's file handler can be inherited and extended to support custom functionality, for example, saving images directly to a database, without using temporary folder.
(http://www.telerik.com/help/aspnet-ajax/asyncupload-extending-handler.html)

I believe I've implemented a custom handler as described in the documentation, but when deployed to a test server running with limited permissions I am seeing: RadAsyncUpload could not create App_Data folder.

My custom handler writes files directly to the database, am I missing something or is the Temp directory always required for the async upload control?

I have DisablePlugins="true" and HttpHandlerUrl="~/Handlers/ImageUploadHandler.ashx"

Please advise.

Thanks,

Adam Nelson

Load-On-Demand: 'Authentication Failed'

I have a RadComboBox following the Load-on-demand PageMethod example. http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx

I am getting an alert with the message 'Authentication Failed' when I click the drop down. The RadComboBox happens to be in a RadGrid and I tried calling the same method on the RadGrid DataItemBound event and the method completed successfully (removing any question of database connectivity issues).

<telerik:RadComboBox ID="uxService" runat="server" DropDownWidth="175px" EmptyMessage="Service:" Height="150px" Width="100px" EnableLoadOnDemand="true" ShowMoreResultsBox="true" EnableVirtualScrolling="true" OnClientBlur="dropDownBlur">

<WebServiceSettings Method="GetServices" Path="TimeCard.ascx" />

</telerik:RadComboBox>

[WebMethod]

public static RadComboBoxData GetServices(RadComboBoxContext context)

{

DataView data = Website.BlueSkyFactory.Time.GetServices(context.Text + "%");

RadComboBoxData serviceData = new RadComboBoxData();

int itemOffset = context.NumberOfItems;

int endOffset = Math.Min(itemOffset + ItemsPerRequest, data.Count);

serviceData.EndOfItems = endOffset == data.Count;

List<RadComboBoxItemData> result = new List<RadComboBoxItemData>(endOffset - itemOffset);

RadComboBoxItemData itemData;

for (int i = itemOffset; i < endOffset; i++)

{

itemData = new RadComboBoxItemData();

itemData.Text = data[i]["FriendlyName"].ToString();

itemData.Value = data[i]["ServiceId"].ToString();

result.Add(itemData);

}

serviceData.Message = GetStatusMessage(endOffset, data.Count);

serviceData.Items = result.ToArray();

return serviceData;

}

Please advise.

Group Header Aggregate

I am attempting to display aggregates in the group header.

I am attempting to use the example from this link:
http://www.telerik.com/help/aspnet-ajax/grid-group-header-footer-templates.html

However I keep getting the following error:

Compiler Error Message: BC30108: 'GridGroupHeaderItem' is a type and cannot be used as an expression.

Source Error:
