Hi,

I use VS and Blend to build a wpf application. When using Blend all of a sudden I get the following error message
The name <telerik control tab/grid> does not exist in the namespace "http://schemas.telerik.com/2008/xaml/presentation"'

I have tried Clean, re-referencing, re-build but to no avail. This error is only in design time in Blend.

any advise?

Hi,

Executing following code recieved strange NullReferenceException:

        private void IterateRows(IList<Record> records)
        {
            foreach (Record record in records)
            {

                if (record is ExpandableDataRecord)
                {
                    ExpandableDataRecord expandableRecord = (ExpandableDataRecord)record;
                    expandableRecord.IsExpanded = true;

                    IterateRows(expandableRecord.ChildRecordManagers[0].Records);
                }
            }
        }

        private void Expand_Click(object sender, RoutedEventArgs e)
        {
            this.IterateRows(this.radGridView1.Records);
        }


System.NullReferenceException was unhandled

Any thoughts?
Just to mention that I don't have r:\WPF_Scrum\WPF_Team\Sources\Development\WPF\GridView\GridView\GridViewItemsControl.cs on my computer ;)

Hello,

i am working with the radtreeview, i want that the default styling on the mouseover should be removed.
Please suggest with code snippet.
Thanks and regards

If the height of the RadChart is not specified in xaml the radchart starts to grow vetically(a lot)  in the designer mode.
this slows down the system. But when the project is run all shows normally.
In the Q1 2009 is going to be ok???

Hi,

What on earth!!!!

Hi,

we (again after a stopped approach due to missing documentation) start a project using your WPF Controls.
We currently use (just for silverlight) another Linear gauge - and there we simply set Orientation="Horizontal".

We messed around a lot with your linear Gauge (documentation became much better) - but could not find out how to creat a horizontal gauge.

The other thing is about Radial Gauge.
We need a 180° Gauge - and had problems to build this with your control.
Neither in the demos - nor in the documentation we find something about how to build such a gauge.
All we found out is, that if Width and Height have different values everything gets "displaced"

Could you please tell us if both (hori - linear / 180* radial) is impossible - or if we simply missed somethin?

Regards

Manfred

Greetings,

I am trying to customize the background of the RadGauge control. Ironically, I stumbled upon Bill's unanswered question here: http://www.telerik.com/community/forums/wpf/gauges/radguage-background.aspx#761772

I am having the exact same problem. How do you replace the default red/orange with a Brush?

Thank you,
Chad Campbell

Hello,

I am trying to figure out how to use the RadGuage control. Currently, I am trying to just change the Background of the gauge. The red/orange colors do not work with my application. How do I replace the default red/orange background with an ImageBrush?

The templates in the documentation found here (http://www.telerik.com/help/wpf/radial-gauge-customizing-appearance.html) do not seem to work. For instance, when I use the templates, the values disappear.

Thank you!

Can someone post the code to Databind the WPF RadGrid with an OpenAccess DataProvider?

I cannot get anything to work!

I am unable to find the support for the right hand Y axis, is it there? :)
