CheckBox firing event on load

[James DAmour]

I'm trying to have a checkbox as a column that fires an event when it is checked or unchecked. The current code does that, but the problem I am facing is that when the grid is loading, it is firing an event for each item in the grid before it displays. Is there a way around this?

                            <telerik:GridViewDataColumn Header="" DataMemberBinding="{Binding IsCheckedInModel, Mode=TwoWay}" >
                                <telerik:GridViewDataColumn.CellTemplate>
                                    <DataTemplate>
                                        <CheckBox IsChecked="{Binding IsCheckedInModel, Mode=TwoWay}" Checked="VarImportance_Checked" Unchecked="VarImportance_Checked"/>
                                    </DataTemplate>
                                </telerik:GridViewDataColumn.CellTemplate>
                            </telerik:GridViewDataColumn>

Thanks,

Hello James,

Upon checking on my side, If internally in the code the IsCheckedInModel is set to true for an item, the CheckBox -> Checked event will be fired. I am not aware of an approach to prevent the Checked method to be called. This is framework specific. What comes up to my mind is to check if the RadGridView is loaded by using IsLoaded property.

private void VarImportance_Checked(object sender, RoutedEventArgs e)
{
    if(this.gridView.IsLoaded)
    {
        // executed your code
    }
}

Hope this approach will work on your side.

Hi Dinko,

Thanks for the response. Unfortunately I had already tried that and the checkboxes initialize after the grid is loaded. Anyway, I'll try some other workaround.
