Okay, I am doing a dataGrid that loads in an XML file and displays it on the screen by using the following...

Code:

private void loadButton_Click(object sender, System.EventArgs e)
{
     mySet = LoadBooks( @"C:\Documents and Settings\Jay\Desktop\C#\pgm2\Books.xml" );
     dataGrid.DataSource = mySet;
}

public DataSet LoadBooks( string strFileName )
{
	DataSet loadSet = new DataSet();
	loadSet.ReadXml( strFileName );
	return loadSet;
}

That part works great. Here's the problem, I also have two text fields for the user to input a <TITLE> and an <AUTHOR>. I cant figure out how to do this and then update it on the screen in the dataGrid. I do not want to add the new book and author directly to the file as I have a save button that will end up doing that for me.

Here's the method prototype that my add book button click will call:

Code:

addBook( mySet, newTitle.Name, newAuthor.Name );

What you want to do is create a new DataRow and add it to the DataSet and then rebind the DataSet to the DataGrid. Then when the user clicks "Save" then you update the XML file. Here's a link showing you how to do that

I had done something similar to what you just posted twister, but I had a problem with my dataset having a duplicate table name inside. If I gave the new one a different name, it wouldn't add it to the same table, but create a new one in the grid.

I ended up finding a simple update method to call on my current table

Thanks for the help guys.
