Hi!

Have a little problem when i want to use the other dataset with the same
grid.

When i display the form i use the UniqueFolders. All works fine, then click
a button
and send InitializeGrid with FileDeletion as parameter and the exception is
raised. (See subject)

What to do? Do i have to clear the datagridview with some method or what?

This is my code:

void InitializeGrid(EGridInitialize gridInitialize)
{
   switch (gridInitialize)
{
   case EGridInitialize.UniqueFolders:
       this.dataGridView1.DataMember =
DataSetUniqueFolders.Tables[0].TableName;
       this.dataGridView1.DataSource = DataSetUniqueFolders;
       this.dataGridView1.Columns[0].HeaderText = "Compare/Delete";
       this.dataGridView1.Columns[1].HeaderText = "Project Path";
       break;
   case EGridInitialize.FileDeletion:
       this.dataGridView1.DataMember =
DataSetUnusedFiles.Tables[0].TableName;
       this.dataGridView1.DataSource = DataSetUnusedFiles; ;
       this.dataGridView1.Columns[0].HeaderText = "/Delete";
       this.dataGridView1.Columns[1].HeaderText = "File";
       this.dataGridView1.Columns[2].HeaderText = "Complete path and file";
       break;
   default:
       break;
   }
}
