如何防止DataGridView共享行? [英] How do I prevent a DataGridView from sharing rows?

问题描述

我已经制作了一个自定义DataGridViewCell，它显示自定义控件而不是单元格；但是，如果DataGridView使用共享行，则自定义控件实例也会共享，因此您会得到奇怪的行为(例如，将鼠标悬停在按钮上会突出显示所有按钮).另外，我无法访问DataGridViewCell.Selected属性，所以我不知道该行用什么颜色绘制.

I've made a custom DataGridViewCell that displays a custom control instead of the cell; but if the DataGridView uses shared rows, then the custom control instance is also shared, so you get strange behaviour (for example, hovering over buttons highlights all the buttons). Also, I can't access the DataGridViewCell.Selected property, so I don't know what colour to paint the row.

如何防止DataGridView共享行?我知道我可以使用Rows.Add(object [])覆盖来添加行，但是第一行仍然是共享的(即索引为-1)，因此颜色问题仍然存在.

How do I prevent a DataGridView from sharing rows? I know I can add the rows using the Rows.Add(object[]) override, but then the first row is still shared (i.e. has index -1) so the problem with colours still applies.

我需要能够告诉DataGridView不共享包含自定义单元格的行.可以使用属性来完成吗?可以做到吗?

I need to be able to tell the DataGridView not to share a row containing a custom cell. Can that be done with attributes? Can it be done at all?

推荐答案

尝试在行"的一个单元格中设置工具提示文本

Try to set a Tooltip Text in one cell of the Row

在以下任何一种情况下都不能共享行:该行包含一个不在选定列中的选定单元格.该行包含其ToolTipText或ContextMenuStrip属性设置的单元格.该行包含一个设置了Items属性的DataGridViewComboBoxCell.

A row cannot be shared in any of the following situations: The row contains a single selected cell that is not in a selected column. The row contains a cell with its ToolTipText or ContextMenuStrip properties set. The row contains a DataGridViewComboBoxCell with its Items property set.
