DataGridView 单元格中的多行 [英] Multiple lines in a DataGridView cell

问题描述

使用C# Windows Forms;

我有一个带有多个单元格的 DataGridView.我想在单元格中显示数字(从 1-9).数字应以 3x3 格式放在一起.

I have a DataGridView with a number of cells. I would like to show digits (from 1-9) in the cell. The digits should be placed under each other in a 3x3 format.

我环顾四周，最终得到了一个相当复杂的 richtextbox 单元的自定义实现.

I looked around, and only ended up with a rather complex custom implementation of a richtextbox cell.

有没有办法绘制一个自定义矩形，然后将其实现为单元格的backgroundimage 或其他什么?单元格需要多次重绘.所以我猜我不能只调用 paint 事件.

Is there a way I can draw a custom rectangle and then implement this as backgroundimage of the cell or something? The cell need to be redrawn several times. So I can't just call the paint event I guess.

注意:用户不得编辑单元格.

推荐答案

我不知道这是否会让您满意，但是您可以使用 Environment.NewLine 在单元格内创建简单的换行符.

Im don't know if this will satisfy you, but you can use Environment.NewLine to create simple line break inside cell.

示例:

string nl = Environment.NewLine; // new line variable
string data = "1 2 3" + nl + "4 5 6" + nl + "7 8 9";

稍后添加:

正如 Adrian 在评论中所说 - 您需要:

As Adrian said in comments - you will need to:

1. 将 DataGridViewColumn 的 WrapMode 设置为 DataGridViewTriState.True

1. set the WrapMode for the DataGridViewColumn to DataGridViewTriState.True

确保为行设置了高度，或者将 DataGridView 的 AutoSizeRowsMo​​de 设置为 DataGridViewAutoSizeRowsMo​​de.AllCells

make sure you set a height for the row, or set the DataGridView's AutoSizeRowsMode to DataGridViewAutoSizeRowsMode.AllCells

如果您不想编辑该列 - 您可以将 DataGridView.Column.ReadOnly 属性设置为 true.

If you don't want to edit that column - you can set DataGridView.Column.ReadOnly property to true.

更新:我花了一段时间才找到带有上述信息的属性.在 VS C# 2017 中，WrapMode 属性位于 datagridview DefaultCellSytle 对话框中.

Update: It took me a while to find this property with the above information. In VS C# 2017 the WrapMode property is located in the datagridview DefaultCellSytle dialog.
