See more: DataTable DataGrid
Hey guys.
1. I've created a Own Class, called "Text" (in my namespace "Data.Core").
2. I've created a DataTable-Object called "oDataTable".
3. I've Added a Column to this Object by using the following Code:
oDataTable.Columns.Add("Deutsch", typeof(Data.Core.Text));
4. I've created several DataRows to this DataTable-Object, which contains Text-Objects
4. I've set the DataTable to the ItemSource of a DataGrid (WPF .Net 4.0) and Bound a String-Property of my Text-Object to display in my Grid.
5. No I want to set a Filter. My First Idea was using the RowFilter-Property of my
DataTables DefaultView-Property. But there appears an EvaluateException:
"Can't convert Data.Core.Text into System.String".
Is there a common way to handle this problem or have I to create a workaround ?

Solution 1

Supply your class with a implicit conversion operator for System.String, see Using Conversion Operators[^] for an explanation.

That really works ?
I've put these code in my "Text"-Class.
<pre lang="c#">
public static implicit operator string(Text t)
return t.Caption;
Caption is a string-Property of my Text-Class.
The same Error occurs :-S
But i have a question to the Conversion operators....
Can there occur a conflict by implement this Conversion for Strings and a "override ToString()-Method" ?
