Freezing a particular column from sorting in sortabletelerikGrid

[CHAITHRA]

Hi,

i have sortabletelrik grid with 10 columns.bt default telerik provides sorting option.

i need to customize the sorting facility,i mean ,say i have these two columns with colums1 and columns2. when i click on column header column1,it should not sort.This can be done by setting isortable=false in XAML.But my problem is,wen i click on column2 for sorting,it takes up the first column data for sorting which should not happen. The data of column1 should be freezed wen ever i click on sort on any column header of the grid,it has to exclude coulmn1 and den sort.

Please see the required output in the example.

Ex  before sort

column1  column2

A1           Oligo 1
C1           Oligo 2
F1           Oligo 3
A2           Oligo 4
B2           Oligo 5

After sort

column1  column2
A1           Oligo 5
C1           Oligo 4
F1           Oligo 3
A2           Oligo 2
B2           Oligo 1

and one more condition is, this freezing should only happen wen sorting is clicked,not by default. Please reply ASAP.

Hello,

Sorting in RadGridView is a data operation and it is item oriented. This means that if you sort on the second column, then the entire item will be sorted based on the property column2 is bound to. For example the query to be executed would be similar to:
orderedSource = source.OrderBy(x=>x.Column2Property) 
where source is the collection assigned as RadGridView.ItemsSource.

Please note RadGridView will not update the items internally, it will just sort them.

You can also check the documentation on Custom Sorting where different options for customization are listed.

Hi,

Sorting in RadGridView is item based. As it turns out there is not a solution to suggest on how to modify the data in the bound items.
