Wpf : How To Tick Checkboxes Based On Selected Checkbox_Id In Database

[jeliey 0]

need ur help :( Ada sapa2 x yg penah guna WPF? harap2 ada la yg boleh membantu... In my wpf, i have successfully saved the selected checkboxes in my database. But i got issue on how to display the checked checkboxes. Lets say there are 7 checkboxes in total, and user ticked 3 out of them. I was able to retrieve the Checkbox_id from database through webservice, but how to bind it to checkboxes? ni table yg aku save checkbox_id: User_ID : 1 Widget_ID : 1,2,3 It should only checked the selected id (1,2,3), but all i got is the whole checkboxes are checked. Please help me fix this...below is my code:

 

 xaml: xaml.cs: XDocument doc = XDocument.Parse(e.Result); 
var query = from i in doc.Descendants("ResultTable") select i; foreach (XElement item in query) { 
selectedWidget = item.Element("Widget_ID").Value; 
} 

for (Int32 i = LBWidget.Items.Count - 1; i >= 0; i--) { 

ListBoxItem item = LBWidget.ItemContainerGenerator.ContainerFromIndex(i) as ListBoxItem;

ContentPresenter myContentPresenter = FindVisualChild(item);

DataTemplate dataTemplate = myContentPresenter.ContentTemplate;

CheckBox chk = dataTemplate.FindName("chk", myContentPresenter) as CheckBox; 

if (selectedWidget != null) { chk.IsChecked = true; } 

}

Hai jeliey, sebelum post code tersebut.. sila gunakan tag [ C O D E ] [ \ C O D E] untuk memudakan kami membaca kod anda...

By the way, check box ini berada didalam list view ke?

Hai jeliey, 

 

Try buat macam ini...

 

 

if (selectedWidget != DBNull.Value) 

{

chk.IsChecked = true; 

} 

Gud luck and happy programming....:D
