Hi,

I currently have 2 issues on the width of a column.

1) if you change the size of the 1st column by dragging the separator and 'hide' the column, you can't get it back. All the other columns can be restored, but the 1st isn't restorable. This only happens when the user can't freeze columns.


2) It seems like the auto-size functionality of the columns only works 1 time. Normally if you resize a column and double-click on the separator, the column will auto-size to the right size. Currently, this doesn't appear to work, with any of the ColumnsWidthMode values.

Hi ,

Few minutes back i've installed RAD controls for WPF.When i tried to acces the quick starts i'm getting error.
Even i couldnt able to access the online version of Quick starts ...its showing error message in browser which something goes like this.

thank you

Could you tell, how i can programmatically  create filter by two (for example) columns? Is it possible?

I download a project from this forum
it was ok
but when I copy the code to my project it fail

this is the code 

var

 

masterFilter = (CompositeFilterDescription)(this.RadGridView1.FilterDescription);

 

 

var subjectFilter = (FieldFilterDescription)masterFilter.FilterDescriptions[0];

 

 

subjectFilter.Values.Add(

"Cats");

this is the error
Error 1 'Telerik.Windows.Data.FieldFilterDescription' does not contain a definition for 'Values' and no extension method 'Values' accepting a first argument of type 'Telerik.Windows.Data.FieldFilterDescription' could be found (are you missing a using directive or an assembly reference?)

 

Hi,
I have create a RadChart based on a datatable that has 2 columns "XValue" and "YValue".

Dim

 

seriesMapping2 As New SeriesMapping

 

seriesMapping2.SeriesDefinition =

New BarSeriesDefinition

 

 

Dim itemMapping2 As New ItemMapping

 

itemMapping2.DataPointMember = DataPointMember.YValue

itemMapping2.FieldName =

"YValue"

 

seriesMapping2.ItemMappings.Add(itemMapping2)

RadChart1.SeriesMappings.Add(seriesMapping2)

 

When i execute the chart, the X axis labels values are 1,2,3, .... and i would like to put here the values of "XValue" column on my datatable. How can i do it?


Also, If I try to put string values to "YValue" column in mi datatable, the chart fails, that is, only numeric values can be put as source of a serie?.

Thanks a lot.

Hi

I am trying to do a simple bar chart showing the following data;

Group               Value

Group 1	140.30
Group 2	5.00
Group 3	81.70

I wish to have the above groups as labels in the x-asis, but the barchart always shows 1,2,3

Can you please give me a simple example on how to achieve the above.

Regards

I would like to style and edit the control template of the RadDatePicker inside Expression Blend.
