DataGrid displays lengths of strings instead of the actual strings
-
Colleagues, Familiarizing myself with DataGrid (and with C# in general). My DataGrid is declared like this:
<my:DataGrid AutoGenerateColumns="True" Margin="74,32,68,103" Name="dataGrid1" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" />
I’m setting the ItemSource property equal to a list of strings.
public Window1()
{
InitializeComponent();List<string> lstGridData = new List<string>(); for (int i = 0; i < 8; ++i) lstGridData.Add("str"); dataGrid1.ItemsSource = lstGridData;}
I’m expecting that grid would display one column and each line would show “str”. Instead, the grid displays one column titled “Length” and each line displays “3”. What am I missing? Cheers, - Nick

The AutoGenerateColumns mechanism binds to any bindable properties it finds in the objects in the List. For a string, that's String.Length.

How can I make a "bindable string"? Is there a framework object with a bindable string property which is commonly used for this purpose? May be, one option is to make a wrapper object with a bindable string property (call it, say, BindableString). Is there a simple/quick solution to "populate DataGrid with primitive values" problem? Tried with manually defined columns (AutoGenerateColumns=False). Didn't work either. Looking for a good DataGrid tutorial... Cheers, - Nick

Manually bind to the object itself...
