Question

我正在尝试在DataGridView单元格中以多行显示文本。我不想使用Wrap模式，因为文本不是很冗长。我只想在第一行显示第一个单词，在下一个单词中显示第二个单词。请注意第二行的粗体文字。

姓名：abc
城市：xyz

我尝试使用Environment.NewLine和“\ r \ n”来完成它，但都不起作用。

private void dgv_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
    {
        foreach (DataGridViewRow dgvrow in dgv.Rows)
        {  
            if (dgv.CurrentCell.ColumnIndex == dgv.Columns["Name"].Index)
            {
                DataGridViewCell dgvcell = (DataGridViewCell)dgvrow.Cells["Name"];
                string Name = dgvcell.Value.ToString();
                string City = Name.Substring(Name.IndexOf("City:"));
                Name = Name.Substring(0, Name.IndexOf("City:")) + Environment.NewLine + City;
                dgvcell.Value = Name;
            }
        }
    }

有谁能建议如何实现这一目标？感谢。

Answer 1

您应该可以通过将WrapMode DefaultCellStyle的{{1}}设置为 true 并设置DataGridViewTextBoxColumn来实现此目的。

Answer 2

试试这个.. 您需要将AutoSizeColumnsMode设置为AllCells。

        foreach (DataGridViewRow dgvrow in dgv.Rows)
        {
            if (dgv.CurrentCell.ColumnIndex == dgv.Columns["Name"].Index)
            {
                DataGridViewCell dgvcell = (DataGridViewCell)dgvrow.Cells["Name"];
                string Name = dgvcell.Value.ToString();
                string City = Name.Substring(Name.IndexOf("City:"));
                Name = Name+"\r\n"+City;
                dgvcell.Value = Name;
            }
        }

它肯定会起作用

Answer 3

我通过处理DataGridView_CellFormatting事件并根据需要格式化文本来修复它。谢谢大家的建议。

Answer 4

这对我有用：

elmo = hub.Module("https://tfhub.dev/google/elmo/2", trainable=True)
tokens_input = [["the", "cat", "is", "on", "the", "mat"],
                ["dogs", "are", "in", "the", "fog", ""]]
tokens_length = [6, 5]
embeddings = elmo(
    inputs={
        "tokens": tokens_input,
        "sequence_len": tokens_length
    },
    signature="tokens",
    as_dict=True)["elmo"]

我有一个类似的困难，因为我想使用换行，但是仅在我指定要换行符换行的地方使用。我的解决方案是根据我不想包装的最长字符串调整列宽的大小，然后让包装完成其余的工作。

请随意尝试以下操作，或对其进行修改以适合您的目的。

private void dataGridView_TextItems_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        if (sender is DataGridView dgv && dgv.Rows[e.RowIndex].Cells[e.ColumnIndex] is DataGridViewTextBoxCell cell)
        {
            SetDGVTextBoxColumnWidth(dgv.Columns[e.ColumnIndex] as DataGridViewTextBoxColumn);
        }
    }

    private void SetDGVTextBoxColumnWidth(DataGridViewTextBoxColumn column)
    {
        if (column != null)
        {
            DataGridView dgv = column.DataGridView;
            Graphics g = dgv.CreateGraphics();
            Font font = dgv.Font;

            // Acquire all the relevant cells - the whole column's collection of cells:
            List<DataGridViewTextBoxCell> cells = new List<DataGridViewTextBoxCell>();
            foreach (DataGridViewRow row in column.DataGridView.Rows)
            {
                cells.Add(row.Cells[column.Index] as DataGridViewTextBoxCell);
            }

            // Now find the widest cell:
            int widestCellWidth = g.MeasureString(column.HeaderText, font).ToSize().Width;  // Start with the header text, but for some reason this seems a bit short.
            bool foundNewline = false;
            foreach (DataGridViewTextBoxCell cell in cells)
            {
                font = ((cell.Style.Font != null) ? cell.Style.Font : dgv.Font);  // The font may change between cells.
                string cellText = cell.Value.ToString().Replace("\r","");  // Ignore any carriage return characters.  
                if (cellText.Contains('\n'))
                {
                    foundNewline = true;
                    cell.Style.WrapMode = DataGridViewTriState.True;  // This allows newlines in the cell's text to be recognised.

                    string[] lines = cellText.Split('\n');
                    foreach (string line in lines)
                    {
                        int textWidth = g.MeasureString(line + "_", font).ToSize().Width;  // A simple way to ensure that there is room for this text.
                        widestCellWidth = Math.Max(widestCellWidth, textWidth);
                    }
                }
                else
                {
                    int textWidth = g.MeasureString(cellText + "_", font).ToSize().Width;
                    widestCellWidth = Math.Max(widestCellWidth, textWidth);
                }
            }
            if (foundNewline)
            {
                column.AutoSizeMode = DataGridViewAutoSizeColumnMode.None;  // Allows us to programatically modify the column width.
                column.Width = widestCellWidth;  // Simply set the desired width.
            }
            else
            {
                column.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;  // Allow the system to do the work for us.  This does a better job with cell headers.
            }
            column.Resizable = DataGridViewTriState.False;  // We don't wish the User to modify the width of this column manually.
        }
    }
