hi! how can i get the column name of the current cell in the radgridview?
RadGridView1 is the name of my datagrid.
these doesn't work:

RadGridView1.CurrentCell.Column.ToString();
RadGridView1.CurrentCellInfo.Column.ToString();
RadGridView1.CurrentColumn.ToString();

help me please...

Try something like this:

string str = dataGridView1.Columns[0].HeaderText;

Hi, to add to ddanbe`s post.
You can do it this way too:

foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                foreach (DataGridViewCell cell in row.Cells)
                { 
                 //CELL here does not have a property of HeaderText.
                    //so you can do it like ddanbe showed or:
                    string header = dataGridView1.Columns[cell.ColumnIndex].HeaderText;
                }
            }

thanks for your suggestion. but it doesn't work. here's the error:

Telerik.Windows.Controls.GridViewColumn does not contain a definition for HeaderText
