Question

我的 GridView 就像这样填充：

<asp:Panel ID="pnlGrid" runat="server">
    <div class="m_container" style="margin-bottom:20px;">
        <asp:GridView ID="grdView" runat="server" CssClass="GridViewStyle"
            AutoGenerateColumns="False" GridLines="None" Width="125%" onrowdatabound="builderGridView_RowDataBound" >
            <Columns>
                <asp:BoundField DataField="id" Visible="False" />
                <asp:BoundField HeaderText="Info" />
                <asp:TemplateField>
                  <ItemTemplate>
                    <asp:LinkButton name='<%#Eval("status") %>' CommandArgument='<%#Eval("id")%>' runat="server" Text='<%#Eval("status")%>' CommandName='<%#Eval("status")%>' ID="statusLink" />
                  </ItemTemplate>
                </asp:TemplateField>
            </Columns>
            <RowStyle CssClass="RowS" />
            <EmptyDataRowStyle CssClass="EmptyS" />
            <PagerStyle CssClass="PagerStyle" />
            <SelectedRowStyle CssClass="SelectedS" />
            <HeaderStyle CssClass="HeaderS" />
            <EditRowStyle CssClass="EditRowS" />
            <AlternatingRowStyle CssClass="AltRowS" />
        </asp:GridView>
    </div>
</asp:Panel>
</asp:Content>

背后的代码是：

Private Sub LoadData(ByRef theStatus As Integer) Dim objConn As MySqlConnection Dim objCmd As MySqlCommand objConn = New MySqlConnection(strConnString) objConn.Open() Dim strSQL As String strSQL = "SELECT * FROM theTable WHERE status=" & theStatus & " ORDER BY created_on, status DESC;" Dim dtReader As MySqlDataReader objCmd = New MySqlCommand(strSQL, objConn) dtReader = objCmd.ExecuteReader() grdView.DataSource = dtReader grdView.DataBind() dtReader.Close() dtReader = Nothing objConn.Close() objConn = Nothing End Sub

然后在上面我为每一行创建一个 LinkButton ，如下所示：

Sub builderGridView_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) If e.Row.RowType = DataControlRowType.DataRow Then Dim lbtn As LinkButton = DirectCast(e.Row.FindControl("statusLink"), LinkButton) e.Row.Cells(1).Text = "TEST!" If lbtn.Text = 0 Then Dim lb As New LinkButton() lb.Text = "Accept" lb.CommandName = lbtn.CommandName lb.CommandArgument = lbtn.CommandArgument lb.Attributes.Add("class", "nounderline") lb.ForeColor = System.Drawing.Color.Green lb.Font.Bold = True lb.Font.Size = 12 lb.OnClientClick = "location.href = '/page.aspx?ID=" & pageID & "&dbid=" & lb.CommandArgument & "&ACCEPT=yes'; return false;" e.Row.Cells(4).Controls.Add(lb) End If End If End Sub

如何从数据库中获取值（名称，地址，电子邮件地址等）并将其放在当前行中？

示例：

（当它循环遍历行时）

e.Row.Cells(1).Text = database("FName") & "<BR />" & database("LName") & "<BR />"...etc etc

在第一行列中看起来像这样：

我怎样才能抓住目前从数据库中读取的内容？

Answer 1

为数据库中的每一行处理builderGridView_RowDataBound事件填充。

e.Row.DataItem将包含数据库中的项目

修改的：更好的方法是

Using adap As New MySqlDataAdapter(objCmd)
    Dim table As New DataTable()
    adap.Fill(table)
grdView.DataSource = table;
grdview.DataBind();

适配器会将所有记录加载到DataTable。

然后你的e.Row.DataItem将是DataRow

类型

ASP.net GridView获取数据库值
