What kind of error do you get?
Is the file missing or is the XML file corrupt or what?

An exception of type 'System.ArgumentException' occurred in System.Data.dll but was not handled in user code

Additional information: Cannot add a nested relation or an element column to a table containing a SimpleContent column.

C#

using System.Data;

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        this.BindGrid();
    }
}
 
private void BindGrid()
{
    using (DataSet ds = new DataSet())
    {
        ds.ReadXml(Server.MapPath(&quot;~/Customers.xml&quot;));
        GridView1.DataSource = ds;
        GridView1.DataBind();
    }
}
 
protected void OnPageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    this.BindGrid();
}

site that original code from Read XML File and bind it to GridView in ASP.Net[^]

use this code

C#

string fileName = System.IO.Path.GetFileName(FileUpload1.FileName);
               FileUpload1.SaveAs(Server.MapPath("~/folder/") + fileName);
               string filePath = "~/folder/" + filename;
               string filePath = Path.Combine(Server.MapPath("~/folder/"), fileName); // should get full path
               Label1.Text = "File uploaded successfully.";

It looks like you might have some XML files with a structure that is not supported by the DataSet class, but it is difficult to help you without seeing the actual XML file.

If it is very large you shouldn't post it here, instead open the XML file in a text editor and try to remove redundant data. Try to load it from time to time to see if you still have the problem. If not, then you kind of know where the problem lies.
If it is small enough you can update your question with the relevant XML data.

Also look for recursive nesting inside the XML file. DataSet doesn't like that very much.
Example:

XML

<root>
    <node>
        <name>Harry Hacker</name>
        <node>
            <name>Mickey Mouse</name>
        </node>
    </node>
</root>
