大家还是先来看看效果吧

C#仿QQ皮肤－ComboBoxDataGridViewC#仿QQ皮肤－ComboBoxDataGridView

下面我们一起来看看是怎么样实现的

这个其实是控件里是没有的，那天在博客上看到一个同志在写这个控件，所性抄一点思想，在结合我和控件就加上了，还挺好用的，呵呵，有了这个控件大家就不用再为绑定一个表那个字段面苦了，可以一下自全部绑定，实现很简单大家一起来看看吧

第一步我们新建一个组件名称 为ComboBoxDataGridView

其实就是dataGridViewHost 和ToolStripDropDown之间的相互配合

这个控件是继承自我皮肤里的控件Combox这个大家一会儿看代码

我们要声明一个委托来调用 构造DataGridViw的方法

publicComboBoxDataGridView()
{
this.SetStyle(ControlStyles.OptimizedDoubleBuffer,true);
DrawDataGridView();
this.OnScroll+=newComboBoxDataGridViewScroll(ComboBoxDataGridView_OnScroll);
}

我们先来看看DrawDataGridView();
方法吧

dataGridView.RowHeadersVisible=false;
dataGridView.RowTemplate.Resizable=DataGridViewTriState.False;//固定行高不允许调节
dataGridView.ColumnHeadersDefaultCellStyle.Alignment=DataGridViewContentAlignment.MiddleCenter;
dataGridView.BackgroundColor=SystemColors.ActiveCaptionText;
dataGridView.BorderStyle=BorderStyle.None;
dataGridView.ReadOnly=true;
dataGridView.AllowUserToAddRows=false;
dataGridView.SelectionMode=DataGridViewSelectionMode.FullRowSelect;
dataGridView.Click+=newEventHandler(dataGridView_Click);

//设置DataGridView的数据源
CRD.WinUI.Forms.EntryFormfrmDataSource=newCRD.WinUI.Forms.EntryForm();
frmDataSource.Controls.Add(dataGridView);
frmDataSource.SuspendLayout();

dataGridViewHost=newToolStripControlHost(dataGridView);
dataGridViewHost.AutoSize=m_blPopupAutoSize;

dropDown=newToolStripDropDown();
dropDown.Width=this.Width;
dropDown.Items.Add(dataGridViewHost);
}

有关DatagridView和Combox的实现 代码大家请参考我的皮肤系统，呵呵

下面我把代码都放上来各们看看吧也提提建议
