DataGridView - Focus a specific cell

How to set focus on any specified cell in DataGridVi开发者_开发百科ew? I was expecting a simple way like Focus(rowindex,columnindex) but it is not that easy.

Set the Current Cell like:

DataGridView1.CurrentCell = DataGridView1.Rows[rowindex].Cells[columnindex]

or

DataGridView1.CurrentCell = DataGridView1.Item("ColumnName", 5)

and you can directly focus with Editing by:

dataGridView1.BeginEdit(true)

you can set Focus to a specific Cell by setting Selected property to true

dataGridView1.Rows[rowindex].Cells[columnindex].Selected = true;

to avoid Multiple Selection just set

dataGridView1.MultiSelect = false;

the problem with datagridview is that it select the first row automatically so you want to clear the selection by

grvPackingList.ClearSelection();
dataGridView1.Rows[rowindex].Cells[columnindex].Selected = true;  

other wise it will not work

I had a similar problem. I've hidden some columns and afterwards I tried to select the first row. This didn't really work:

datagridview1.Rows[0].Selected = true;

So I tried selecting cell[0,0], but it also didn't work, because this cell was not displayed. Now my final solution is working very well:

datagridview1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;    
datagridview1.CurrentCell = datagridview1.FirstDisplayedCell;

So this selects the complete first row.

public void M(){ 
  dataGridView1.CurrentCell = dataGridView1.Rows[0].Cells[0];
  dataGridView1.CurrentCell.Selected = true; 
  dataGridView1.BeginEdit(true);
}

Just Simple Paste And Pass Gridcolor() any where You want.

Private Sub Gridcolor()
    With Me.GridListAll
        .SelectionMode = DataGridViewSelectionMode.FullRowSelect
        .MultiSelect = False
        '.DefaultCellStyle.SelectionBackColor = Color.MediumOrchid
    End With
End Sub

in event form_load (object sender, EventArgs e) try this

dataGridView1.CurrentCell = dataGridView1.Rows[dataGridView1.Rows.Count1].Cells[0];

this code make focus on last row and 1st cell

            //For me it's the best way to look for the value of a spezific column
            int seekValue = 5;
            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                var columnValue = Convert.ToInt32(row.Cells["ColumnName"].Value);
                if (columnValue == seekValue)
                {
                    dataGridView1.CurrentCell = row.Cells[0];
                }
            }

 private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
    {
        int row = e.RowIndex;
        int col = e.ColumnIndex;
        if (row < 0 || col != 3)
            return;
        if (e.FormattedValue.ToString().Equals(String.Empty))
        {
        }

        else
        {
            double quantity = 0;
            try
            {
                quantity = Convert.ToDouble(e.FormattedValue.ToString());
                if (quantity == 0)
                {
                    MessageBox.Show("The quantity can not be Zero", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
                    e.Cancel = true;
                    return;
                }
            }
            catch
            {
                MessageBox.Show("The quantity should be decimal value.", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
                e.Cancel = true;
                return;
            }
        }
    }

You can try this for DataGrid:

DataGridCellInfo cellInfo = new DataGridCellInfo(myDataGrid.Items[colRow], myDataGrid.Columns[colNum]);
DataGridCell cellToFocus = (DataGridCell)cellInfo.Column.GetCellContent(cellInfo.Item).Parent;
ViewControlHelper.SetFocus(cellToFocus, e);
