如何在數據列表中顯示網格視圖的選定行

Question

我正在獲取GridView的row的值，但是將數據綁定到DataList 。 DataList是沒有得到明顯

aspx

<asp:GridView ID ="gvresults" runat="server" 
       onselectedindexchanged="gvresults_SelectedIndexChanged">
   <Columns>
       <asp:ButtonField ButtonType="Button" CommandName="Select" Text="Select" />
   </Columns>
</asp:GridView>
<asp:DataList ID ="dlresults" runat="server"></asp:DataList>

aspx.cs

protected void gvresults_SelectedIndexChanged(object sender, EventArgs e)
{
    string Keywordid = gvresults.SelectedRow.Cells[1].Text;
    string val1 = gvresults.SelectedRow.Cells[2].Text;
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["conStr"].ConnectionString);
    DataSet ds = new DataSet();
    SqlCommand cmd = new SqlCommand("select * from Tbl_keywords where KeywordID ='" + Keywordid + "'",con);
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    da.Fill(ds);
    dlresults.DataSource = ds;
    dlresults.DataBind();
}

Answer 1

您應該這樣寫：

dlresults.DataSource = ds.Tables[0];   
dlresults.DataBind();
dlresults.DataKeyField = "SomeKey";
dlresults.Visible = true;

在您的asp代碼中：

<asp:DataList ID ="dlresults" runat="server">
      <ItemTemplate>
                <asp:Label runat='server' ID='lblItemName' Text='<%# DataBinder.Eval(Container.DataItem, "someVal") %>'>
                </asp:Label>
     </ItemTemplate>
</asp:DataList>
