Hi,

I am experiencing this issue when I am working on creating a dynamic
datagrid. Please let me know if there is any work around for this
problem. If I am posting this in the wrong newsgroup please point me
to the right newsgroup.

Issue: A DataTable-bound DataGridView throws a low-level Exception
when columns are sorted, removed and re-added to the underlying
DataTable.

Steps to replicate the issue:
1. Create a DataTable.
2. Create a DataGridView and bind it to the DataTable.
3. Populate the datatable with data
4. SORT a column of the DataView (Exception is not thrown without this
step).
5. Remove the column of DataTable that was sorted.
6. Add a new column to the DataTable.
7. Try to add data to that column - Exception is thrown.

Sample Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1
{
   public partial class UserControl1 : UserControl
   {
       DataGridViewTextBoxColumn col1;
       DataGridViewTextBoxColumn col2;
       DataGridViewTextBoxColumn col3;
       DataColumn datacol1;
       DataColumn datacol2;
       DataColumn datacol3;

       public UserControl1()
       {
           InitializeComponent();

           col1 = new DataGridViewTextBoxColumn();
           col1.Name = "col1";
           col1.HeaderText = "col1";
           col1.DataPropertyName = "col1";
           col1.SortMode = DataGridViewColumnSortMode.Automatic;

           col2 = new DataGridViewTextBoxColumn();
           col2.Name = "col2";
           col2.HeaderText = "col2";
           col2.DataPropertyName = "col2";

           col3 = new DataGridViewTextBoxColumn();
           col3.Name = "col2";
           col3.HeaderText = "col2";
           col3.DataPropertyName = "col2";

           datacol1 = new DataColumn("col1",
System.Type.GetType("System.String"));
           datacol2 = new DataColumn("col2",
System.Type.GetType("System.String"));
           datacol3 = new DataColumn("col3",
System.Type.GetType("System.String"));
       }

       private void button2_Click(object sender, EventArgs e)
       {
           // add col1 and col2 columns to datagridview
           dataGridView1.Columns.Add(col1);
           dataGridView1.Columns.Add(col2);

           // add columns to the datatable
           dataTable1.Columns.Add(datacol1);
           dataTable1.Columns.Add(datacol2);

           // add rows
           dataTable1.Rows.Add(new object[] { "a", "b" });
           dataTable1.AcceptChanges();

           // sort
           dataGridView1.Sort(col1, ListSortDirection.Ascending);

           // remove sorted column col1
           dataGridView1.Columns.Remove("col1");
           dataTable1.Columns.Remove("col1");

           //add new column col3
           dataGridView1.Columns.Add(col3);
           dataTable1.Columns.Add(datacol3);

           // try to add rows - exception is thrown here
           dataTable1.Rows.Add(new object[] { "z", "p" });
           dataTable1.AcceptChanges();

       }
   }
