如何在DataGridViewColumnHeaderCell类中使用自定义控件(用户控件或继承的控件)来编写自定义headerCell? [英] How to use a custom control (User control or a inherited control) into DataGridViewColumnHeaderCell class to write a custom headerCell?

问题描述

大家好..
我想为从dataGridView继承的控件编写自定义headerCell.
如何在DataGridViewColumnHeaderCell类中使用自定义控件(用户控件或继承的控件)?对于通用控件，例如通过CheckBoxRenderer.DrawCheckBox(...) .我只想知道用户控制或继承的控件怎么可能????
谢谢..

假设这是我的自定义headerCell:
< pre lang ="c#">
公共类DataGridViewComboBoxHeaderCell:DataGridViewColumnHeaderCell
{


公共DataGridViewComboBoxHeaderCell()
{

}
UnitConvertorComboBox.UnitConvertorComboBox组合=新的UnitConvertorComboBox.UnitConvertorComboBox();

受保护的重写void Paint(System.Drawing.Graphics图形，
System.Drawing.Rectangle clipBounds，
System.Drawing.Rectangle cellBounds，
int rowIndex，
DataGridViewElementStates dataGridViewElementState，
对象值，
对象formattedValue，
字符串errorText，
DataGridViewCellStyle cellStyle，
DataGridViewAdvancedBorderStyle advancedBorderStyle，
DataGridViewPaintParts paintParts)
{
base.Paint(graphics，clipBounds，cellBounds，rowIndex，
dataGridViewElementState，值，
formattedValue，errorText，cellStyle，
advancedBorderStyle，paintParts);
}
}
</pre>
这是我的自定义控件，它继承自combobox:
< pre lang ="c#">
公共局部类UnitConvertorComboBox:ComboBox
{
//构造函数
公共UnitConvertorComboBox()
{
}

</pre>

Hello every body..
I want to write a custom headerCell for a control inherited from dataGridView.
how it''s possible to use a custom control(user control or a inherited control) into a DataGridViewColumnHeaderCell class? for a common control it''s easy for example for check box by: CheckBoxRenderer.DrawCheckBox(...); . I just want to know how it''s possible with user control or a inherited one????
Thanks ..

This is suppose to be my custom headerCell:
<pre lang="c#">
public class DataGridViewComboBoxHeaderCell:DataGridViewColumnHeaderCell
{


public DataGridViewComboBoxHeaderCell()
{

}
UnitConvertorComboBox.UnitConvertorComboBox Combo = new UnitConvertorComboBox.UnitConvertorComboBox();

protected override void Paint(System.Drawing.Graphics graphics,
System.Drawing.Rectangle clipBounds,
System.Drawing.Rectangle cellBounds,
int rowIndex,
DataGridViewElementStates dataGridViewElementState,
object value,
object formattedValue,
string errorText,
DataGridViewCellStyle cellStyle,
DataGridViewAdvancedBorderStyle advancedBorderStyle,
DataGridViewPaintParts paintParts)
{
base.Paint(graphics, clipBounds, cellBounds, rowIndex,
dataGridViewElementState, value,
formattedValue, errorText, cellStyle,
advancedBorderStyle, paintParts);
}
}
</pre>
And this is my custom control which inherited from combobox:
<pre lang="c#">
public partial class UnitConvertorComboBox : ComboBox
{
//Constructor
public UnitConvertorComboBox()
{
}

</pre>

推荐答案

我已经通过注释中提到的方式解决了.但是有些事情我只能再打一次.效果很好！！！

I''ve solved by the way which was mentioned in comments. But there is something that i must call just one time not any more. It works fine!!!
