i have page load to load gridview from database and i have textbox and search button can change the gridview. but that problem is gridview_selectindexchanging select wrong row.

        protected void GridView1_SelectedIndexChanging1(object sender, GridViewSelectEventArgs e)
    {

        lbl_1.Visible = true;
        lbl_2.Visible = true;
        lbl_3.Visible = true;
        lbl_4.Visible = true;
        lbl_5.Visible = true;
        lbl_6.Visible = true;

        lbl_nama.Text = GridView1.Rows[e.NewSelectedIndex].Cells[1].Text;
        lbl_alamat.Text = GridView1.Rows[e.NewSelectedIndex].Cells[2].Text;

        DateTime kembali = DateTime.ParseExact(lbl_pengembalian.Text,"dd-MM-yyyy",CultureInfo.InvariantCulture);
        if (DateTime.Now > kembali)
        {
            lbl_denda.Text = "Rp.20000,-";
        }
        else
        {
            lbl_denda.Text = "Rp.0,-";
        }
    }

            <asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" style="text-align: left" AutoGenerateSelectButton="true" OnSelectedIndexChanging="GridView1_SelectedIndexChanging1">
            <AlternatingRowStyle BackColor="White" />
            <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
            <PagerStyle BackColor="#FFCC66" ForeColor="#333333" HorizontalAlign="Center" />
            <RowStyle BackColor="#FFFBD6" ForeColor="#333333" />
            <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" />
            <SortedAscendingCellStyle BackColor="#FDF5AC" />
            <SortedAscendingHeaderStyle BackColor="#4D0000" />
            <SortedDescendingCellStyle BackColor="#FCF6C0" />
            <SortedDescendingHeaderStyle BackColor="#820000" />
        </asp:GridView>

推荐答案

我想你可能会寻找 EnablePersistedSelection 属性。

I think you may be looking for the EnablePersistedSelection property.

获取或设置一个值，该值指示行的选择是
  基于索引或数据键值

Gets or sets a value that indicates whether the selection of a row is based on index or on data-key values

如果此属性为false并选择一排，同样排
  当显示一个新的页面，即使新的页面选择
  在它的不同的数据。如果此属性，当你设置为true
  显示中有不同的数据的页面，没有行被选中。如果
  你然后返回到其上选择的行的页面，该行是
  仍处于选中状态。

If this property is false and a row is selected, the same row is selected when a new page is displayed even though the new page has different data in it. If you set this property to true, when you display a page that has different data in it, no row is selected. If you then return to the page on which a row was selected, that row is still selected.
