Hello Telerik,

I wanted to implement a column chooser for a grid. Then I followed this doc here

http://docs.telerik.com/devtools/wpf/controls/radgridview/features/overview-controlpanel

and found out that I basically just need to add this piece of code inside my grid to achieve the desired feature.

 
Now my question is:
Is there a way I can reuse this block of code in several grids? Such as via usercontrols?

I just want to keep my code clean.
please show me the way.
Thank you!

I have learned that RadGridView has data validation feature per cell and row. But in my case, I want data validation on GridView level. In my app, I have "Purchase Order Form". In this form, there is RadGridView for Purchase Order Items. The validation scenario is User must add at least one item to this RadGridView.

I use the way of Data Annotation and Validation Attribute in my ViewModel to check this validation.

[CollectionHasElements( ErrorMessage = "Purchase order must have at least one order item." )]
        public ObservableCollection<PurchaseOrderItemDecorator> PurchaseOrderItemDecorators
        {
            get { return _purchaseOrderItemDecorator; }
            set { SetProperty( ref _purchaseOrderItemDecorator, value ); }
        }

The RadGridView successfully notify the error by showing Red Border around the grid. But it somehow failed to show the error message. I attached the screenshot of this RadGridView.

In normal telerik wpf controls, it usually shows the error message on top right corner red block triangle. I wish my Gridview act like that for showing validation error message.

Thanks.

am facing a problem in richtext box 

i want to load data through  "D:\file.ext" but it shows me error 

string cannot convert to stream or byte

I have created a RadCartesianChart that shows live data coming in from a machine in a factory that charts the weight of each unit.

Using this xaml:

With this code-behind:

Then as data comes in, I add doubles to the dbl variable. This all works well but my horizontal axis starts with no datapoints, therefore no demarcation ticks, and the spread of the first datapoints is ridiculously wide, until it reaches a hundred and then I start removing the zeroeth point and adding the next one at the end. Then it maintains a stable appearance.

I have written a hack by adding 100 datapoints with "0" value like this:

But I wonder if there isn't a "proper" way to get the desired result.

Hello,

It could be possible to represent X axis and Y axis into bottom side and right hand, respectively?
