ResultFormatString with static property?

Hello,

We have Q3 2012.

I'm trying to use a static property to specify the ResultFormatString for an AggregateFunction,

<telerik:GridViewDataColumn.AggregateFunctions>
        <telerikData:SumFunction ResultFormatString="{x:Static l:CustomFormat.CurrencyWithMinus}"/>
</telerik:GridViewDataColumn.AggregateFunctions>

But the property's value (e.g. $#,##0.00) is displayed as a literal in the gridview cell. 

We can't use the string format "c" because we need negative values to be prefixed with "-" 
rather than having parentheses around them.  Can you please tell me if there's some way to make this work?

Thanks much!

IsEditable="True"

IsLoadOnDemandEnabled="True"

ItemTemplate="{StaticResource ItemTemplate}"

ItemEditTemplate="{StaticResource EditTemplate}"

IsDragDropEnabled="True"

telerik:TreeViewSettings.DragDropExecutionMode="New"

telerik:RadDragAndDropManager.AllowDrop="True"

telerik:RadDragAndDropManager.AllowDrag="True" ...>

<i:Interaction.Triggers>

<commands:DragDropQueryRoutedEventTrigger EventName="DropQuery" EventOwnerType="{x:Type telerik:RadDragAndDropManager}">

<micro:ActionMessage MethodName="OnDropQuery" >

<micro:Parameter Value="$eventArgs" />

</micro:ActionMessage>

</commands:DragDropQueryRoutedEventTrigger>

</i:Interaction.Triggers>

</telerik:RadTreeView>

my method is something like this:

public void OnDropQuery(DragDropQueryEventArgs args)

{

...

args.Handled = true;

}

Validation errors in WPF Windows8Touch

We are using the telerik:StyleManager.Theme = "Windows8Touch" for TextBox.
The validation errors using IDataErrorInfo are being displayed as seen in the attached screenshot.
Is there a way to have the flyouts automatically align to the Left of the control, if there is no space on the right?

Hi ,
Am using a RadGridview control to populate my data and using the ElementExporting event to customize the data while exporting to Excel.

My customization need goes like, I want to add some metadata(some info the grid like report name, date generated, owner etc , at the top A1 cell ) to the grid data that is getting exporting . beneat that my actual grid data should be shown, and it should be sorted as my need.
I could able to append the metadata using the

grdRiskClarityReport.Export(stream,

new GridViewExportOptions()

{

Format=

ExportFormat.Html,

ShowColumnHeaders =

true,

ShowColumnFooters =

true,

ShowGroupFooters =

false,

});

and my event goes like this,

private void grdRiskClarityReport_ElementExported(object sender, GridViewElementExportedEventArgs e)

{

if (e.Element == ExportElement.HeaderCell && temp== 0)

{

// if (obj != null)

{

e.Writer.Write(

String.Format(@"<tr><td style=""background-color:#CCC;"" colspan=""{0}"">","dfdfd"));

e.Writer.Write(

String.Format(@"<b>Proposal Name:</b> {0} <br />", "dfdfd")); //need to input properdata

e.Writer.Write(

String.Format(@"<b>Proposal Status:</b> {0} <br />", "dfdfd"));

e.Writer.Write(

"</td></tr>");

temp = 1;

// using the restrict the metadata to the first cell

}

Could you please provide me a sample in wpf version that serves my need ?

Items Load Direction with VirtualQueryableCollectionView

Hi,

I am using the Virtual Queryable Collection View with the telerik Grid Views. When I scroll using the Mouse Wheel and the Scroll Direction is Down it calls the Items Loading event which lets me fetch the next set of view models; However when the scroll direction is UP using the Mouse Wheel I would like to load the set of View Models which are above the current item. This will avoid firing the Items Loading event for every single Item when scrolling UP using the Mouse Wheel.

Please refer the image file attached for more details.

Thanks,
PD.

Tree Item Style

I am somewhat new to WPF and styling, but I understand most of the basics.

I have managed to modify the expander as well as a few other items.

But one simple thing has escaped me - styling the foreground of the RadTreeViewItem.

This:
<Style TargetType="{x:Type telerik:RadTreeViewItem}">
<Setter Property="Foreground" Value="#ffff0000"/>
</Style>
is not only not setting the font color, but no items show up.

Any help? I'm sure it's simple.

Also, I second the suggestion for more examples and perhaps more documentation.

This is my favorite page: http://www.telerik.com/help/wpf/radtreeview-structure.html

Thanks!
