我在datagrid某列動態的添加dropdownlist,現在如何獲得在客戶端對每行作的選擇,即獲得dropDownlist.selectitem.text
DataGrid.AutoGeneratecolums=true
Some Code:
If btnEdit.Text = "編輯" Then
btnEdit.Text = "保存"
For i = 0 To dropdownlist.Items.Count - 1
Dim ddlgrade As New DropDownList
ddlgrade.ID = Me.ClientID & i.ToString
ddlgrade.Width = Unit.Pixel(50)
DropDownList.Items(i).Cells(DropDownList.Items(i).Cells.Count - 1).HorizontalAlign = HorizontalAlign.Center
BindDataToDdlGrade(ddlgrade, DropDownList.Items(i).Cells(DropDownList.Items(0).Cells.Count - 1).Text)
DropDownList.Items(i).Cells(DropDownList.Items(0).Cells.Count - 1).Controls.Add(ddlgrade)
Next

Else
btnEdit.Text = "編輯"
