Hello,

My RadComboBox is always enabled in my DataForm even if I'm not in EditMode. 

I try this w/o success :

1) Set by default IsEnabled="false" my RadComboBox
2) In the BeginningEdit event : ((RadComboBox)DataFormfiche.FindNameInContent("CategoriesComboBox")).IsEnabled = true;    
3) In the EditEnding event :  ((RadComboBox)DataFormfiche.FindNameInContent("CategoriesComboBox")).IsEnabled = false; 

Always disabled!

A big thank you for your help Seree :

XAML File :

 

<

 

toolkit:DataForm Name="DataFormfiche" EditEnding="DataFormfiche_EditEnding" BeginningEdit="DataFormfiche_BeginningEdit" Background="Beige" Width="1024" CommandButtonsVisibility="Add, Cancel, Commit, Delete, Edit, Navigation" ItemsSource= "{Binding Data, ElementName=ficheDomainDataSource}" AutoGenerateFields="False" AutoCommit="False" AutoEdit="False" AddingNewItem="DataFormfiche_AddingNewItem" ContentLoaded="DataFormfiche_ContentLoaded" Loaded="DataFormfiche_Loaded" EditEnded="DataFormfiche_EditEnded">

 

 

 

 

...

 

 

<toolkit:DataField Grid.Row="5" Grid.Column="0" HorizontalAlignment="Left">

 

 

 

 

 

 

<telerik:RadComboBox Name="NoCategorieComboBox" IsEnabled="False"  SelectedValue="{Binding NoCategorieEspaceClos, Mode=TwoWay}" SelectedValuePath="NoCategorie" Width="240" Height="25" ItemsSource="{Binding Source={StaticResource categoriesespacesclosDomainDataSource}, Path=Data}" DisplayMemberPath="DescriptionCategorie_fr" />

 

 

 

 

 

 

 

</toolkit:DataField>

 

 

 

 

...

 

 

</DataTemplate>

 

</

 

toolkit:DataForm.EditTemplate>

 

</

 

toolkit:DataForm>

XAML.CS File

 

 

private void DataFormfiche_BeginningEdit(object sender, System.ComponentModel.CancelEventArgs e)

 

{

((

RadComboBox)DataFormfiche.FindNameInContent("NoCategorieComboBox")).IsEnabled = true;

 

}

 

private void DataFormfiche_EditEnding(object sender, DataFormEditEndingEventArgs e)

 

{

((

RadComboBox)DataFormfiche.FindNameInContent("NoCategorieComboBox")).IsEnabled = false;

 

}

Hi Louis,

Please try setting IsEnabled by using ContentLoaded instead of BeginningEdit/EditEnding.

void FormDetails_ContentLoaded(object sender, DataFormContentLoadEventArgs e) 
        { 
            var lookup = (FormDetails.FindNameInContent("ComboLookup") as RadComboBox);             
            if (e.Mode == DataFormMode.ReadOnly) 
            { 
                lookup.IsEnabled = false
            } 
            else 
            { 
                lookup.IsEnabled = true
            } 
        } 


Hope this help.

Best regards,
Seree W.

Hello Seree,

Thank you for your code.  I try it and the code excute fine but the control stay in the same state (enabled).

The DataForm need to be refresh or something like this?

It's working now.  Thank you for the information Seree, you help me to find the final solution.  THe only difference, I use direct reference to the RadComboBox.

            //var lookup = (DataFormficheespacesclos.FindNameInContent("ComboBoxQuantite") as RadComboBox);
            if (e.Mode == DataFormMode.ReadOnly)
            {
                //lookup.IsEnabled = false;
                ((RadComboBox)DataFormficheespacesclos.FindNameInContent("NoCategorieEspaceClosComboBox")).IsEnabled = false;
            }
            else
            {
                ((RadComboBox)DataFormficheespacesclos.FindNameInContent("NoCategorieEspaceClosComboBox")).IsEnabled = true;
                //lookup.IsEnabled = true;
            } 

Have nice day.
