[Solved] Error GridViewSelectColumn auto uncheck when Scroll

[balv]

Hi All,

I have a project using Q3 2010 SP1. when I use a RadGridView with GridViewSelectColumn to selection rows.If the data is less than height of GridView(has no vertical scrollbar) then the select column works well. But If the data is more than height,After select the first row,I scroll to bottom and select the checkbox column in the bottom page, now I scroll back to top of the page then the checkbox of first row is auto unchecked. How can I fix this bug?
Thanks in advance.

Hi balv,

I have tested the scenario you described but I was not able to encounter the behavior you reported. May you provide a bit more details on your settings ? Do you set the SelectionUnit or SelectionMode properties of the grid ?

Yes, I do not set SelectionUnit property
SelectionMode="Extended"
ScrollMode="RealTime"
...
ItemSource is loaded by a ViewModel
Morever, when I transform to next page and back then all checkbox(ischecked=true) auto is cleared
Thanks

Hello,

I am still not able to reproduce the issue with the un-checking of an already checked CheckBox on scrolling. I am sending you the sample project I used for testing the case. Please take a look at it and let me know in case of any misunderstandings.
Considering the clearance of the selected items on moving through pages, this is the expected behavior since once you move on the another page, the SelectedItems collection is cleared.

Best wishes,
