Datagridview编辑/保存按钮

Question

I have a datagridview table displaying some customer information from an SQL table. I have added a datagridviewbuttoncolumn on the end to allow editing of a single row at a time. However, I cannot even get basic functionality to work with the button. The UseColumnTextForButton property doesn't seem to work, nor when I progrommatically try to change the text.

private void CardList_grdvw_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        var senderGrid = (DataGridView)sender;

        if (senderGrid.Columns[e.ColumnIndex] is DataGridViewButtonColumn &&
            e.RowIndex >= 0)
        {
            senderGrid.Rows[e.RowIndex].ReadOnly = false;
            var btn = (DataGridViewButtonCell)senderGrid.CurrentCell;
            btn.Value = "save";
        }
    }

I have checked to verify that the correct cell is being referenced. When debugging, after I set btn.Value = "save" it still is null .

Additionally, the row is still un-editable even after setting its ReadOnly property to false .

By default, the Text property of a column in the DataGridView is blank. I think you are confusing the HeaderText and Text properties. When you set the UseColumnTextForButton to true, the buttons will use the Text property of the column.

Make sure you supply that Text property in the designer.

To make the code you posted work, set the UseColumnTextForButton back to false.
