WinForms DataGridView: Prevent Enter from moving to the next row and move focus to another column in the same row

Hi @Shahmeer .R

from datagridview uncheck enable adding options so no new row will not add. when edit row add event not perform.

Thanks.

Hello @Shahmeer .R ,

To override the default Enter key navigation in a DataGridView so that it stays on the same row and moves to a specific column, the recommended approach is to override the ProcessCmdKey method at the Form level. This allows you to intercept the Enter key press before the DataGridView handles it and moves the selection down.

Here is an example demonstrating how you can achieve this:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    // Check if the Enter key was pressed and the focus is in the "Qty" column
    if (keyData == Keys.Enter && 
        dataGridView1.CurrentCell != null && 
        dataGridView1.CurrentCell.OwningColumn?.Name == "Qty")
    {
        // 1. Finish editing the current cell so its value is committed
        dataGridView1.EndEdit();

        // 2. Perform your calculations here 
        // (e.g., updating amount, discount, profit based on the new Qty)

        // 3. Move the focus to the "NetRate" column on the same row
        int currentRowIndex = dataGridView1.CurrentCell.RowIndex;
        dataGridView1.CurrentCell = dataGridView1.Rows[currentRowIndex].Cells["NetRate"];

        // 4. Return true to consume the key press, preventing the default behavior
        return true; 
    }

    // For all other keys and columns, retain the default behavior
    return base.ProcessCmdKey(ref msg, keyData);
}

In short:

• ProcessCmdKey catches the key press early.
• EndEdit() ensures that whatever value the user just typed into the cell is committed to the underlying cell/data source before your calculations run.
• Returning true tells the framework that the keystroke has been handled, which specifically prevents the grids built-in behavior of moving to the next row.

Let me know if it works for you. I would greatly appreciate it if you could follow this guidance or provide feedback. Thank you.

I am currently handling the issue and will provide an update soon. Thank you for your patience.
