Change editable area of datagridview

How, when user click on a text cell of a datagridview, the editable area of the cell became bigger than the cell(span 3 rows and 2 columns), which make it easier for the user to edit

Thanks

    You can change the rowheight but not the width



    private void dataGridView1_DefaultValuesNeeded(object sender, DataGridViewRowEventArgs e)
    {
    dataGridView1.Rows[e.Row.Index].Height = dataGridView1.RowTemplate.Height * 3;
    }
    private void dataGridView1_RowLeave(object sender, DataGridViewCellEventArgs e)
    {
    dataGridView1.Rows[e.RowIndex].Height = dataGridView1.RowTemplate.Height;
    }

    Hi,

    How about doing in the following way Hope it helps.

    private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)

    {

    if (e.Control is TextBox)

    {

    Rectangle rect = this.dataGridView1.GetCellDisplayRectangle(this.dataGridView1.CurrentCell.ColumnIndex, this.dataGridView1.CurrentCell.RowIndex, false);

    int curHeight = rect.Height;

    this.dataGridView1.CurrentRow.Height = curHeight * 2;

    DataGridViewCellStyle style = new DataGridViewCellStyle();

    style.Alignment = DataGridViewContentAlignment.TopLeft;

    this.dataGridView1.CurrentCell.Style = style ;

    TextBox tx = e.Control as TextBox;

    tx.Multiline = true;

    }

    }

    private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)

    {

    this.dataGridView1.CurrentRow.Height = this.dataGridView1.RowTemplate.Height;

    }

    Regards.

    Ye

    First of all, why it is done in DefaultValuesNeeded() Does it handle the "Cell Clicked" or "Cell Entered" event

    Second, I don't means to change the height of the row. Instead, the size of the editing control inside the cell should be changed.

    Thanks a lot!

    For resizing of cell width, you can adjust the width of the current column, as:

    this.dataGridView1.Columns[e.ColumnIndex].Width = // width you want to set.
