How to select visible columns in Datagridview bound to DataTable

Question

I have these fields on Customer DataTable: ID,title,Name,Addrs,email,Fax and this code to bind the DataGridView:

Answer 1

I know this post goes way back, but I had the same problem in C# and this is how I solved it which works really well.

1 - Build a DataSet with your SQL query

     private void LoadDS()
     {
         // this method gets data from my database
         // DS is a DataSet in the properties of my form
         DS = LoadData();
     }

2 - Get the DataView filtered the way you want

For this I use the RowFilter property of the DataView. I created a GetFiltersToString() method that formats every filter control I have in a string that matches the RowFilter syntax (more information about the syntax here, and msdn definition of RowFilter here)

    public void RefreshDGV()
    { 
        // Get the corresponding dataview
        DV = new DataView(DS.Tables[0], rowFilter, "SORTINGCOLUMN Desc", DataViewRowState.CurrentRows);
        // Display it in a datagridview
        DGV.DataSource = DV;
    }

I find that this solution allows user to change the filtering much more easily.
