GridView Paging bug when using custom row control template element loaded.
When the first element is loaded and its set to IsEnabled = false then the first element on the next page is also set to IsEnabled to false.
bet when i go to the page number 3 and go back then is everything ok.
XAML:
<CheckBox Name="assembledCheckBox"
Margin="0,0,0,0"
FontWeight="Bold"
FontSize="10"
Grid.Row="1"
Grid.Column="1"
VerticalAlignment="Center"
HorizontalAlignment="Left" Content="Assembled"
IsChecked="{Binding a_status}" Loaded="assembledCheckBox_Loaded"
>
private void assembledCheckBox_Loaded(object sender, RoutedEventArgs e)
{
CheckBox temp = new CheckBox();
temp = (CheckBox)sender;
if (temp.IsChecked == true)
{
temp.IsEnabled = false;
}
}

Generally, it is not recommended to work with visual elements directly when they are placed in GridView's row or cell. This is because of GridView's UI Virtualization mechanism which ensures recycling of the grid's rows and cells. This means that the Loaded event of your checkbox will be raised when RadGirdView reloads its rows. The recommended approach would be to work with the data items. In order to help you further, you can share more information about your scenario.

Hello Yoan,
The scenario is simple the custom row has 3 checkbox's.
The checked value is selected from database values true or false. If the value is true the checkbox should be checked and isEnabled set to false. If value is false for the first checkbox should be not checked and enabled, but all the subs should be disabled.
And if the first is checked then the secod should be enabled and so on...

This should be easy to achieve using only your business object. I have created a sample project which demonstrates a possible approach. Please give it a try and let me know how it works for you.
