Hi,<br />
<br />
I am using a treeview and the treeview-nodes will be loaded from a xml-file.<br />
It uses a DataSet to do this.<br />
<br />
1. Is there a tool where i can check the syntax of my xmlfile?<br />
2. I have an error message:<br />
<br />
&quot;Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.&quot;<br />
<br />
And I don't know what it means and what to do about it?<br />
<br />
Who knows the answer and is willing to help me?<br />

Hi,

I am using a treeview and the treeview-nodes will be loaded from a xml-file.
It uses a DataSet to do this.

1. Is there a tool where i can check the syntax of my xmlfile?
2. I have an error message:

"Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."

And I don't know what it means and what to do about it?

Who knows the answer and is willing to help me?

Question about xml

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
