以编程方式向 gridview 添加一行 VB
Adding a row to a gridview programmatically VB
VS 2013,VB。 ASP.NET
我的页面上有一个 gridview。
<asp:GridView ID="gvSteam" runat="server" AutoGenerateColumns="False" CssClass="gvSteam">
<Columns>
<asp:BoundField DataField="Generation" HeaderText="Steam Generation (Capacity)" ReadOnly="True" SortExpression="DisplayName" />
<asp:TemplateField HeaderText="TPH" ItemStyle-HorizontalAlign="Center" ItemStyle-Width="100px">
<ItemTemplate>
<asp:Label ID="lblValueEnergy" runat="server" Text='<%# Format8888(Eval("Power")) %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<HeaderStyle BorderColor="Black" BorderStyle="Solid" BorderWidth="1px" />
</asp:GridView>
后面的代码如下
Dim Asset As New Assets
Dim Allsteam As New List(Of Assets)
Allsteam = Asset.GetSteamGenerated()
gvSteam.DataSource = Allsteam
gvSteam.DataBind()
我想在特定点(例如第 4 行之后)向 gridview 添加一个空白行,并向其中添加一些文本。
我可以使用数据表作为示例,但我使用的是 gridview,并且更愿意这样做。
按以下方式排序,可能不是最好的方法,但很管用。
Dim newRow As GridViewRow
For Each newRow In gvSteam.Rows
If newRow.RowIndex = 3 Then
Dim row As New GridViewRow(4, 4, DataControlRowType.EmptyDataRow, DataControlRowState.Normal)
Dim tc As New TableCell
tc.ColumnSpan = 2
Dim lbl As New Label
tc.Controls.Add(lbl)
lbl.Text = "Steam Turbine 11"
row.Controls.Add(tc)
gvSteam.Rows(4).Parent.Controls.AddAt(4, row)
End If
Next
