ASP.NET-GRIDVIEW各種大小事記錄

RowDataBound

取DataKey：

GridVeiw.DataKeys(e.Row.RowIndex).Value.ToString

FindControl一定要服用：

If e.Row.RowType = DataControlRowType.DataRow Then

判斷操作模式：

If e.Row.RowState = DataControlRowState.Edit Then

FindControl：

Dim ddl As DropDownList = CType(e.Row.FindControl("ddl_PROC_KIND"), DropDownList)

偶數列無法判斷解決：

If e.Row.RowState = DataControlRowState.Edit OrElse CInt(e.Row.RowState) = 5 Then

RowCommand 

FindControl：

Dim ddl1 As DropDownList = DirectCast(DirectCast(e.CommandSource, Control).FindControl("欄位名稱"), DropDownList)

取DataKey：

• Dim row As GridViewRow = DirectCast(DirectCast(e.CommandSource, Control).NamingContainer, GridViewRow)
• Dim pk As Integer = Convert.ToInt32(GridView.DataKeys(row.RowIndex).Values(0))
• 如果有設定多個的話，就1、2、3
