Detect blank row in datagridview

Question

@Jack J Jun , sir This is an another problem that , i am facing in the same datagridview project .
current-cell-focus-problem-after-using-cellendedit.html

As the focus reaches to the last cell of last row and last column , pressing enter key creates a new row and focus moves to that . What i am trying to achieve is if the value of first column of this newly created row gets empty after the user presses enter , the focus should move to the next control instead of next cell in same row .The intention is to get out of datagridview instead of moving to next cell .

  this.SelectNextControl((Control)sender, true, true, true, true);   

but i am out of idea where to detect the blank first cell value so as to use the above code .

@ankit goel , you could try the following code to delete blank row and move the focus to next control.

private void Form1_Load(object sender, EventArgs e)  
        {  
            DataTable table=new DataTable();  
            table.Columns.Add("Name");  
            table.Columns.Add("Age");  
            table.Columns.Add("Id");  
            table.Rows.Add("test1", 22, 1001);  
            table.Rows.Add("test2", 22, 1002);  
            table.Rows.Add("test3", 22, 1003);  
            dataGridView1.DataSource = table;  
            dataGridView1.AllowUserToAddRows = false;  
        }  
  
        private void dataGridView1_KeyDown(object sender, KeyEventArgs e)  
        {  
            //e.SuppressKeyPress = true;  
            int iColumn = dataGridView1.CurrentCell.ColumnIndex;  
            int iRow = dataGridView1.CurrentCell.RowIndex;  
            if (e.KeyCode == Keys.Enter)  
            {  
                //to check if the pointer reach last column  
                if (iColumn == dataGridView1.ColumnCount - 1&&iRow== dataGridView1.RowCount - 1)  
                {  
                    //executing when line ends  
                    e.Handled = true;  
                    this.SelectNextControl((Control)sender, true, true, true, true);  
  
                }  
                 
            }  
             
        }  

Based on my test, it works well.

Best Regards,
Jack
