如何将 DataGridView 文本框列设置为多行？

Question

如何让“ DataGridViewTextBoxColumn ”中DataGridView支持多行属性？

Answer 1

您应该能够通过将DataGridViewTextBoxColumn的DefaultCellStyle的WrapMode设置为true来实现这一点。

Answer 2

I have found that there are two things that you need to do, both in the designer, to make a text cell show multiple lines. As Tim S. Van Haren mentioned, you need to set WrapMode of the DefaultCellStyle of your DataGridViewTextBoxColumn to true . And although that does make the text wrap, it doesn't make the row expand to show anything beyond the first line. In addition to WrapMode , the AutoSizeRowsMode of the DataGridView must be set to the appropriate DataGridViewAutoSizeRowsMode enumeration value. A value such as DataGridViewAutoSizeRowsMode.AllCells allows the cell to expand vertically and show the entire wrapped text.

Answer 3

Apart from setting WrapMode of the DefaultCellStyle , you can do the following:

1. You need to catch GridView's EditingControlShowing Event
2. Cast Control property on the EventArgs to the type you want (ie textbox, checkbox, or button)
3. Using that casted type, change the Multiline property like below:

private void MyGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    TextBox TB = (TextBox)e.Control;
    TB.Multiline = true;            
}

Answer 4

    int multilineht = 0;
    private void CustGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        multilineht = CustGridView.Rows[CustGridView.CurrentCell.RowIndex].Height;
        CustGridView.AutoResizeRow(CustGridView.CurrentCell.RowIndex, DataGridViewAutoSizeRowMode.AllCells);
    }

    private void CustGridView_CellEndEdit(object sender, DataGridViewCellEventArgs e)
    {
        CustGridView.Rows[CustGridView.CurrentCell.RowIndex].Height = multilineht;
    }

Answer 5

如果您只想为DataGridView一列设置 Multiline 属性，您可以这样做

dataGridView.Columns[0].DefaultCellStyle.WrapMode = DataGridViewTriState.True;
