CheckBox in CellTemplate gets unchecked on scrolling

[Ramya]

Hi,
I have a GridViewDataColumn and I have put a checkbox in its CellTemplate. The problem is that when I check this checkbox and scroll down, the checBox gets unchecked. Though the uncheck event is not fired, it looks unchecked. I have not applied any style to the checkbox. What can be the reason? How can I fix this.
Thanks,
Ramya

Hi Ramya,

This behavior may be caused in the case the IsChecked property of the CheckBox is not bound. May you post some more information about the definition of the column ?

We have also this problem. The checkbox elements are bound:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Exkl}">
    <telerik:GridViewDataColumn.Header>
        <TextBlock Text="ausschl." />
    </telerik:GridViewDataColumn.Header>
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
            <CheckBox IsChecked="{Binding Exkl}" HorizontalAlignment="Center" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

If I scroll the grid, loosed the checkbox the state and the grid select any other checkbox.

Hello Mario,

I have tried to reproduce the issue, but still without any success. May you take a look at the sample attached to verify whether I am testing it correctly ? Can you get the same behavior on this project ?

Thanks for your fast reply.
 
Your example works fine. But the same code in my solution still give the issue.
Our hierarchy look like:
 
controls:ChildWindow
    telerik:RadTabControl
        telerik:RadTabItem

the grid has follow attributes

<telerik:RadGridView ShowGroupPanel="False" telerik:StyleManager.Theme="Transparent"
 ItemsSource="{Binding Source={StaticResource ourSource}}" SelectionMode="Multiple" AutoGenerateColumns="False">

I dont know, what seems the difference.

Hi Mario,

Even after changing the project so that it uses the structure you mentioned, I am not able to reproduce the issue. I am attaching the updated sample. May you take a look and try to reproduce the behavior on this application ? 

All the best,

We are having a similair issue in Winforms.  As we scroll around our grid, we see green-checked checkboxes (which are properly checked) AND black-checked ones that seemingly randomly check and uncheck themselves as we scroll up and down.  Any ideas?

Hi Kevin,

This forum targets only RadControls for Silverlight. I will encourage you to post your question on the appropriate forum for WinForms.
Thank you for your understanding.

HI there.

We´re catching the same problem. Didi anyone find the solution or the reason for this problem to happen?

Thanks in advanced.

Hello Abilio,

Will it be possible to clarify which controls you work with - for WPF or WinForms ? If it is the first case, could you reproduce the behavior in the sample attached ? 

Kind regards,

I'm still getting the behaviour using WPF. Any update on this?

Hello Aaron,

May I kindly ask you to open a separate thread in the WPF section since this topic is for Silverlight and share some sample code demonstrating how the RadGridView is defined on your end? Can you also make sure that the property is databound? 

Thank you in advance for your understanding.
