In google chrome, when page containing silverlight plugin is loaded, it shows silv. control as transparent. If I click somewhere on the page or any other window, it shows it correct (with colors) as expected.
IE and FireFox do not have this problem.
Can anybody suggest me the solution.

Thank you.

I don't know whether it is officially declared as supported. We are using it and works on google chrome. (There can be the issues like the one I mentioned).

Chrome is NOT currently listed as a supported browser for the current plugin version.

It's not officially supported but Scott Guthrie has declared it as working. Maybe at some point it will be officially supported. The Silverlight component I am developing at work appears to work OK so far in Chrome.

TreeView in a ListView

Hi
I have a ListView control with several columns.
The left most column in the ListView contains a TreeView. When expanded this TreeView is limited in width to the column in where it is placed. Is it possible to span the TreeView over multible columns in the ListView?

I'm trying to make something like this:
http://www.c-sharpcorner.com/UploadFile/jibinpan/ASP.NET05152006134544PM/Images/masterDetqail.gif

The only thing missing is the childs capability to span multible columns.

Can anyone help?

The first that comes to mind is the ColumnSpan property, not sure it is a property of ListView though. Could you rework the other columns into a Grid, and then your treeview could be placed in a cell with ColumnSpan="3".

One possibility could be to create the treeview as an adorner, which sits in the adorner layer.

I have a group of 3 radio button. I would like to databind a integer value variable to control them. For example, if variable is 2, then radio button 2 is check while the rest is not.

Any suggestion to the implementation?

I would do something along these lines, maybe somebody else has a better idea!

List<bool?> vals = new List<bool?>
vals.Add(false)
vals.Add(true)
vals.Add(true)

void SetVal(int index)
{
  foreach(bool? b in vals)
     b=false;

  vals[index] = true;
}

XAML

<RadioButton x:name="rb1" IsChecked="{Binding Path=vals[0]}"/>
<RadioButton x:name="rb1" IsChecked="{Binding Path=vals[1]}"/>
<RadioButton x:name="rb1" IsChecked="{Binding Path=vals[2]}"/>

You are looking for an effect similar to a RadioButtonList.

The bad news: WPF doesn't ship with one of these by default.

The good news: They are fairly easy to put together, and there are numerous samples. Here's[^] a good one from Matthew Macdonald. If you haven't bought the Pro WPF book (there are C# and VB.NET editions), you owe it to yourself to buy this book now - it's a fantastic resource.

Hiren,

Can you rephrase your question. Its not clear what you need help with.

FYI: In WPF you can add almost any control to ItemsControl.

I want to use TreeListView in my project. something like

http://www.codeproject.com/KB/list/treelistview.aspx

TreeView with checkbox as well as expander button(+,-) like in win explorer.
And ListView containing ComboBox, DateTimeControl and textbox.

Also tell me from where do i start learning WPF.
Triggers, XAML, items control, data binding etc.

Thanks

Hiren,

There are tutorials here on Code Project.

Both Josh Smith and Sacha Barber has writen great tutorials.

You can also use the Internet to research any topic in WPF.

You can also purchase a book from Amazon.com.

I like Matthew McDonald's book on WPF. He has one for C# and VB.NET.

You can use the WPF TreeView control to do what you want.

Suggest doing an Internet search on "wpf treeview" and you'll get plenty of examples.
