i have a datagridview with 5 columns,when i press "enter" it goes to the next cell and when it arrives to the end of the rows when i press enter it adds a new rows,but my problem is when i move to the previous rows after i press enter it jumps the rows and does not go to the next cells,any help?
public partial class Form1 : Form
{
public static int Col;
public static int Row;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
dataGridView1.AllowUserToAddRows = false;
dataGridView1.Rows.Add();
}
private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
{
Col = dataGridView1.CurrentCellAddress.X;
Row = dataGridView1.CurrentCellAddress.Y;
}
private void Form1_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (int)Keys.Enter)
{
if (Col + 1 < 5)
{
dataGridView1.CurrentCell = dataGridView1[Col + 1, Row];
}
else
{
dataGridView1.Rows.Add();
dataGridView1.CurrentCell = dataGridView1[Col - 4, Row + 1];
}
}
}
}
Forget about CellEnter event and the Form1_KeyPress event also. Just handle the dataGridView1_KeyDown event like this:
private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyData == Keys.Enter)
{
int col = dataGridView1.CurrentCell.ColumnIndex;
int row = dataGridView1.CurrentCell.RowIndex;
if (col < dataGridView1.ColumnCount - 1)
{
col ++;
}
else
{
col = 0;
row++;
}
if (row == dataGridView1.RowCount)
dataGridView1.Rows.Add();
dataGridView1.CurrentCell = dataGridView1[col, row];
e.Handled = true;
}
}
Please note that I changed the code a bit, and remember to set the Handled event property to true, otherwise it will process the default behavior.
Cheers!
because the keyDown envent will not fire when press enter on datagridview cell this will be best thanks to @Nagarjun
bool notlastColumn = true;
protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg,System.Windows.Forms.Keys keyData)
{
int icolumn = dataGridView1.CurrentCell.ColumnIndex;
int irow = dataGridView1.CurrentCell.RowIndex;
int i = irow;
if (keyData == Keys.Enter)
{
if (icolumn == dataGridView1.Columns.Count - 1)
{
//dataGridView1.Rows.Add();
if (notlastColumn == true)
{
dataGridView1.CurrentCell = dataGridView1.Rows[i].Cells[0];
}
dataGridView1.CurrentCell = dataGridView1[0, irow + 1];
}
else
{
// to pass hidden cell, because will fire exception
//exception: Current cell cannot be set to an invisible cell
// the do while loop will enable you to pass any hidden cell
do
{
icolumn++;
} while (!dgv[icolumn, irow].Visible);
dataGridView1.CurrentCell = dataGridView1[icolumn, irow];
}
return true;
}
else
if (keyData == Keys.Escape)
{
this.Close();
return true;
}
//below is for escape key return
return base.ProcessCmdKey(ref msg, keyData);
}
Try using this:
bool notlastColumn = true;
protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg, System.Windows.Forms.Keys keyData)
{
int icolumn = dataGridView1.CurrentCell.ColumnIndex;
int irow = dataGridView1.CurrentCell.RowIndex;
int i = irow;
if (keyData == Keys.Enter)
{
if (icolumn == dataGridView1.Columns.Count - 1)
{
//dataGridView1.Rows.Add();
if (notlastColumn == true)
{
dataGridView1.CurrentCell = dataGridView1.Rows[i].Cells[0];
}
dataGridView1.CurrentCell = dataGridView1[0, irow + 1];
}
else
{
dataGridView1.CurrentCell = dataGridView1[icolumn + 1, irow];
}
return true;
}
else
if (keyData == Keys.Escape)
{
this.Close();
return true;
}
//below is for escape key return
return base.ProcessCmdKey(ref msg, keyData);
//below is for enter key return
return base.ProcessCmdKey(ref msg, keyData);
}
Just copy and paste the code.
