Hi,

We are using OnDemandLoad and binded tree with our datastructure. Howevere in certain case say if A is true then we do not want a certain node say Node1 to expand eventhough it gets data on demand i.e. only parent Node1 should be shown but no Childrens of it but at the same time we do not want to remove it from out binded datasource - in essence we need to hide them from tree.

Hope you get the problem. Please provide us ways/code lines to achieve this.

Thanks in advance,
Balaram

Hi

I try to use a SumFunction in a GroupDescriptor in the following way
 

but I get this error-

No method 'Sum' on type 'System.Linq.Enumerable' is compatible with the supplied arguments.

I have seen this in other WPF control, but last time I play with RadTreeView, then when the scrollbar appears.
It use the System Default Theme (in my System it was windows XP Style), it's feel weird because all other aspek of RadTreeView rendered using applied Theme.

Hi there,

This may be quite simple, but can someone please tell me how to change the styling of labels (font, size, color etc) for RadialGuages and LinearGuages.

Also, I've tried the following code to get SemiCircle gauge styles working.


However I get the following error:

An error occurred while finding the resource dictionary "/Telerik.Windows.Controls.Gauge;component/Themes/Office_Black/NormalView.Styles.xaml".

Thanks for your help

Hi,

I'm not sure if I do something wrong or if GridView simply insist on it's own designtime data.
I create a WPF project in expression blend 3 - add a RadGridView and create some DTD.
Binding it to RadGridView brings what I expected.
But after a build - I have northwind back again.
Here is how it looks:

Hello,

here is my problem. I created a RadGriewView in my form and I have to use my own filters with it, so I use the following method:

        private void majradgridviewglobale()
        {
            if (this.filtresactifs.Count.Equals(0))
            {
                this.radGridView1.ItemsSource = TableResult;
            }
            else
            {
                DataTable tablevide = new DataTable();
                foreach (DataTable table in this.filtresactifs)
                {
                    tablevide.Merge(table);
                }
                this.radGridView1.ItemsSource = tablevide;
            }
        }

where filtresactifs is a datatablecollection and tableresult the datatable filled with the "unfiltered" data.

What happens is when I use the GridView filters (the checkboxes to select rows), then my own filter methods, everything works fine. When I uncheck the filters (the ones from the gridview) to cancel the gridview filter, my data is stuck to what it was when the filters from the grid view where active (even when nothing is checked!).

I did try to debug it and it seems that the DataTable given to radGridView1.ItemsSource are correct so I'm afraid I don't have much clue about this.

Can you give me a hint about this? Thanks.

PS: Excuse if my English is not that good, but I'm not a native speaker so I'm doing my best.

PS2: It looks like only the checkboxes are a problem, when I use the option "filters", looks like it works.

Hi

I noticed that the default RadGridView style does not provide a gray row when a Row is selected but not active; window with both textbox and gridView; select line in gridView; line is blue; activate textbox (click or tab); selected line is still blue.

I tried to modify this behavior inside a GridViewRow style using a Multitrigger but it seems that Selector.IsSelectionActive is always false.

This is my current GridViewRow template : 

   <Style TargetType="{x:Type telerik:GridViewRow}">
           
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type telerik:GridViewRow}">

                            </Grid.ColumnDefinitions>

Do you have any idea how to solve this ?

Hi,

I am using the chart control with SeriesMappings.  Once I define a custom layout, like below, the chart no longer shows data.

Are SeriesMappings not possible with custom layouts?

Thanks,
Pauly
