我hava在这里提出你的问题:组合框帮助,设置第一个字符默认 [ ^ ]
另一种方式:
01:红色
04:绿色
09:蓝色
023:黑色< br $>
initial:
Combo1.Text = Combo1.List(023)
I hava alredy your question here :Combo boxes help, set first character to default[^]
another way:
"01:red"
"04:green"
"09:blue"
"023:black"
initial:
Combo1.Text = Combo1.List("023")
我假设你已经在代码隐藏中绑定了你的组合框。
I assume you have binded your combobox in codebehind.
Dim cmd As New SqlCommand(Query, connection)
Dim dt As New DataTable()
Dim da As New SqlDataAdapter(cmd)
da.Fill(dt)
Dim dr As DataRow = dt.NewRow()
dr("column name") = "Your default text here"//We created default row that needs to be entered at first position
dt.Rows.InsertAt(dr, 0)//Inserted at first place
ComboBox.DataSource = dt
ComboBox.DataBind()
