有现成的demo可用--可自己改造为FlexGrid下来，出现一个FlexGrid：

c1FlexGrid1.Cols[1].Editor = c1DropDownControl1;
this.c1DropDownControl1.DropDownFormAlign = C1.Win.C1Input.DropDownFormAlignmentEnum.Right;
this.c1DropDownControl1.DropDownFormClassName = "ControlExplorer.Input.DropDowns.ImageMapping";

复制代码

效果截图：

ControlExplorer.Input.DropDowns.ImageMapping 自定义一个Form，继承自DropDownForm

public partial class ImageMapping : C1.Win.C1Input.DropDownForm
{
Hashtable ht;
public ImageMapping()
{
InitializeComponent();
this.Open += ImageMapping_Open;
}
void ImageMapping_Open(object sender, EventArgs e)
{
object obj = OwnerControl.Value;
}
private void ImageMapping_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'c1NWindDataSet.Categories' table. You can move, or remove it, as needed.
this.categoriesTableAdapter.Fill(this.c1NWindDataSet.Categories);
}
private void c1FlexGrid2_Click(object sender, EventArgs e)
{
object obj = c1FlexGrid2.Selection.Data;
if (obj != null)
{
OwnerControl.Value = obj;
CloseDropDown();
}
else
{
OwnerControl.Value = "None Selected";
}
}
}

复制代码

现成的demo，有更多的功能可深入挖掘挖掘：

VB.net代码：

c1FlexGrid1.Cols(1).Editor = c1DropDownControl1
Me.c1DropDownControl1.DropDownFormAlign = C1.Win.C1Input.DropDownFormAlignmentEnum.Right
Me.c1DropDownControl1.DropDownFormClassName = "ControlExplorer.Input.DropDowns.ImageMapping"

复制代码

Public Partial Class ImageMapping
Inherits C1.Win.C1Input.DropDownForm
Private ht As Hashtable
Public Sub New()
InitializeComponent()
AddHandler Me.Open, AddressOf ImageMapping_Open
End Sub
Private Sub ImageMapping_Open(sender As Object, e As EventArgs)
Dim obj As Object = OwnerControl.Value
End Sub
Private Sub ImageMapping_Load(sender As Object, e As EventArgs)
' TODO: This line of code loads data into the 'c1NWindDataSet.Categories' table. You can move, or remove it, as needed.
Me.categoriesTableAdapter.Fill(Me.c1NWindDataSet.Categories)
End Sub
Private Sub c1FlexGrid2_Click(sender As Object, e As EventArgs)
Dim obj As Object = c1FlexGrid2.Selection.Data
If obj IsNot Nothing Then
OwnerControl.Value = obj
CloseDropDown()
Else
OwnerControl.Value = "None Selected"
End If
End Sub
End Class

VB.net源码demo：
需要自己替换数据库：app.config文件里面“connectionString=&quot

rovider=Microsoft.Jet.OLEDB.4.0;Data Source=&quot;C:\Users\rogerwang\Documents\Visual Studio 2012\Projects\C1_WF_C1FlexGrid\C1_WF_C1FlexGrid\C1NWind.mdb&quot;"
