问题描述

嗨.
我想做一个像DataGridViewNumericUpDownCell
这样的自定义DataGridViewCell
我有以下课程:

Hi.
I want to make a custom DataGridViewCell like a DataGridViewNumericUpDownCell

I have the following classes:

public class DataGridViewNumericUpDownColumn : DataGridViewTextBoxColumn
{
    //...
}
public class DataGridViewNumericUpDownCell : DataGridViewTextBoxCell
{
    //...
}
class NumericEditingControl : NumericUpDown, IDataGridViewEditingControl
{
    //...
}

一切工作都很好，除了编辑控件不会扩展到单元格边界之外.我该怎么办?

Everything works great, except for the fact that the editing control doesn''t expand beyond the cell bounds. How could I do this?

推荐答案

public override void PositionEditingControl(bool setLocation, bool setSize, System.Drawing.Rectangle cellBounds, System.Drawing.Rectangle cellClip, DataGridViewCellStyle cellStyle, bool singleVerticalBorderAdded, bool singleHorizontalBorderAdded, bool isFirstDisplayedColumn, bool isFirstDisplayedRow)
{
    cellBounds = new System.Drawing.Rectangle(cellBounds.X, cellBounds.Y, cellBounds.Width + 16, cellBounds.Height);
    cellClip = new System.Drawing.Rectangle(cellClip.X, cellClip.Y, cellClip.Width + 16, cellClip.Height);
    base.PositionEditingControl(true, true, cellBounds, cellClip, cellStyle, singleVerticalBorderAdded, singleHorizontalBorderAdded, isFirstDisplayedColumn, isFirstDisplayedRow);
}
