    I'm betting you just need to refresh the datagrid. Try this:

    dataGridView1.Rows.Clear();
    dataGridView1.Refresh();
    

    If this works... you might want to rethink this part of your application.

    DataGridView.DataSource = DataTable; else if you trying to to clear your Data Grid View just code this: DataGridView.DataSource = null; DataGridView.Rows.Clear(); DataGridView.Refresh(); and add any method or event to bind Data Grid View Again below this line of code.

    Basically below code line is only useful in data binding scenarios

    datagridview.DataSource = null; 
    

    otherwise below is the used when no data binding and datagridview is populated manually

    dataGridView1.Rows.Clear();
    dataGridView1.Refresh();
    

    So, check first what you are doing.

    You cant clear the datagrid by just making the datasource into nothing..but you should clear your dt or data table like.dt.clear() the it

    If you want clear a dataGridView not binded to DataSource but manually loaded you can use this simple code:

    datagridview.Rows.Clear();
    datagridview.Columns.Clear();

    This method is useful to clear the current selection without canceling the selection of the cell, row, or column indicated by the exception indexes. If the SelectionMode property value allows individual cell selection, this method sets the Selected property of each cell to false , excluding the cell in the row and column specified.
