It seems WPF version has the same problem as the following
http://www.telerik.com/community/forums/silverlight/general-discussions/textbox-using-chinese-keyboard-results-in-catastrophic-failure-0x8000ffff.aspx

I know this problem of silverlight was issued "http://www.telerik.com/support/pits.aspx#/public/silverlight/4584 ".

I'm wondering will it be fixed at the same time silverlight will?

Hi all,

I have the requirement to show the images in my RadGridView where the alternate row color is Light blue and dark blue.
I have small images (of cancel,danger etc ) which i cut it from the screenshot , so its background is of white color.

So i want images to look such that in the row that its background color(at present white) get matched with the background color (light/dark blue) od the row of the RadGridView or can say it white part can be done transparent in order to match with the row color.


Thanks in Advance !!!!!!!

I've tried to change groupings in the dataloaded event but I get an error message:
"Cannot change ObservableCollection during a CollectionChanged event."

Hello,

By default, when you bind a column to a boolean value, it gets rendered as a checkbox.  Is there any built-in support to render "True" or "False" instead, or do I need to use a Value Converter?  (I just want to make sure that I have not missed some simple setting somewhere.)

Thanks,
Mark

To set the scene, I am in an MVVM environment and I am using the Behavior from Vlad's blog post located at
How To: Synchronize your UI selected items with your data context using MVVM and Blend behaviors for Silverlight and WPF

This behavior works great and I have it bound to a ViewModel, I am working on extended this so when the user selects a row, the grid will automatically select any rows that have the same PO Number as the selected row.

View Model Code:

Here, the SelectedLineItem property is bound to the SelectedItem property of the RadGrid, LineItems is an ObservableCollection of business objects that serves as the ItemsSource of the RadGrid.

I then made the following changes in the Behavior:

So rather then transferring the Grid's selected items to the SelectedItems dependency property I reverse it and transfer the SelectedItems dependency property into the Grid's selected items.



This works and if I look at the Grid.SelectedItems property in a watch it shows me a count of 2.  However the UI only displays one row selected.

Is there a way to force the Grid to re-draw?  Is there a better way to accomplish what I am trying to do?

Any help is greatly appreciated.

I am attempting to use this style of  combobox:

http://blogs.telerik.com/vladimirenchev/posts/10-04-09/how_to_filter_as_you_type_radgridview_inside_radcombobox_for_wpf_and_silverlight.aspx

The combobox from this tutorial is then being added to a grid view as a template column.  The combobox seems to work in the regards that it filters as you type and displays the results in a grid format.  However, when you select an item from the results the combobox dropdown stays open and the selection does not appear to have registered (even though the view model does in fact register the selected item).  Also tabbing from the combox box to the next grid column does not work.  Instead it tabs within the results grid.

Basically I want to interact with the combobox as if it were a combox box grid column.  I just want the combobox to display the results as I type in a grid format.

Any suggestions?

Hi,

Recently we found one show stopper bug after we moved to telerik controls version 2010.2.812. In this version TrasitionControl seems had serious changes. We use transition control inside datatemplates and rendering of views is done mostly with datatemplates.

Thanks for any help.

Hi.

I am to provide a graph that indicate deviation from a set point.

There are five significant points on the Y axis
* Upper scale limit.
* Upper alarm limit
* The desired point (set point).
* Lower alarm limit.
* Lower scale limit.

These can be, for instance
High Scale : 100
High Alarm: 80
Set Point : 50
Low Alarm: 20 
Low Scale: 0.

They can also be,
High Scale : 100
High Alarm: 80
Set Point : 76
Low Alarm: 10 
Low Scale: 0.
 
These two sets of axis settings should draw the exact same Y Axis. Even in the case where the distance from High Alarm to set point is just 4 units and distance from Set Point to Low Alarm is 56 units, they should take equal amount of space of the drawing area. A linear dataset would draw a gently sloping curve from Low Alarm to Set Point, but it would be very steep from Set Point to High Alarm as the whole distance would be covered in just 4 units.

How do I achieve this? I consider using four stacked curves that would each cover one area of the curve on the scale for its area so that it would only APPEAR to be a single curve, but would actually be four different curves. This, however functionally adequate, does not draw a continuous curve. Any better suggestions?

I am using Telerik chart control and I want to set the minor ticks on X axis.
I tried this.

radChartROIComparison.DefaultView.ChartArea.AxisX.MinorTicksVisibility = Visibility.Visible;

But compilation fails telling that

Error 1 'Telerik.Windows.Controls.Charting.AxisX' does not contain a definition for 'MinorTicksVisibility' and no extension method 'MinorTicksVisibility' accepting a first argument of type 'Telerik.Windows.Controls.Charting.AxisX' could be found (are you missing a using directive or an assembly reference?) 

What is the reason for this????

Am I using an old version which does not support this property?

Rangana
