Here's the code: OnClientClick="javascript:SaveQuotaGroupCode('<%# Container.DataItem %>');" The container is a collection of strings. Why is it not evalu...
Morning folks, I think I've got my head around basic databinding in WPF, but I'm not sure how to go about this problem. I have a datagrid that the user adds items to, and I'm trying to make one column a 'depends on' column, so that when the column is in edit mode it contains a dropdown box of all the names of the items in the datagrid e...
Hi everyone, Normally we bind a textbox's Text property to a data-context's properties.

What I want to do: bind two textboxes to two different data context in the same form. How c...

So, if I had the string "Hello $name! We're please to have you visit, $name!", you could pass an array or something and get the resultant string from it. Something like th...
If I have a grid with a list of items (IList<x>) and a textbox on the form, is there a way to bind the data so that as I click a row that the textbox.text gets updated, without doing it explicitly? In other words, I want to be able to use Binding() or some other way, and not do OnSelectionChanged textbox.text = x.somefield as I will...

I've seen a lot of WPF Binding examples and have used the feature in a lot of different places in learning MVVM, but something that has seemed quite inconsistent to me is when you specify "Path=" in the binding string as appose to simply typing in the property you want to bind to. For example, what's the functional difference between the...
