c# - 单击 gridview 中的选择按钮时页面刷新

Question

每当我尝试在 Gridview 中单击搜索按钮或选择按钮时，它都会加载并向上滚动整个页面。我想把它留在原地。怎么样？

代码:

<asp:TextBox ID="txtComplaintSubject" runat="server" CssClass="textField_width"></asp:TextBox>&nbsp
            <asp:Button ID="btnSearch"  CssClass="btn btn-success" runat="server" Text="Search" 
             ValidationGroup="AdminRole" ClientIDMode="Static" OnClick="btnSearch_Click" />

             <asp:GridView ID="gridViewComplaints" AutoGenerateSelectButton="true" runat="server" CssClass="mGrid" OnSelectedIndexChanged="gridViewComplaints_SelectedIndexChanged">
              <EmptyDataRowStyle BorderStyle="None" ForeColor="Red" BorderWidth="0px" />
               <EmptyDataTemplate>
                  No Data Found for this Input. Try Again.
               </EmptyDataTemplate> 
             <SelectedRowStyle CssClass="selected-row" BackColor="YellowGreen" ForeColor="white" />
             </asp:GridView>



protected void btnSearch_Click(object sender, EventArgs e)
    {
        ManageComposedLetter mngCompLetter = new ManageComposedLetter();
        DataTable dt = mngCompLetter.FillGridView_Complaints(txtComplaintSubject.Text);
        if (dt.Rows.Count > 0)
        {
            gridViewComplaints.DataSource = dt;
            gridViewComplaints.DataBind();
        }
        else
        {
            dt.Rows.Add(dt.NewRow());
            gridViewComplaints.DataSource = dt;
            gridViewComplaints.DataBind();
            int totalcolums = gridViewComplaints.Rows[0].Cells.Count;
            gridViewComplaints.Rows[0].Cells.Clear();
            gridViewComplaints.Rows[0].Cells.Add(new TableCell());
            gridViewComplaints.Rows[0].Cells[0].ColumnSpan = totalcolums;
            gridViewComplaints.Rows[0].Cells[0].Text = "No Data Found";
        }

如果你想在页面刷新后停留在相同的位置，只需添加

MaintainScrollPositionOnPostback="true"

在你的 aspx 文件的顶部，所以它看起来像这样:

<%@ Page Language="C#" MaintainScrollPositionOnPostback="true" AutoEventWireup="true" CodeBehind="Default.aspx.cs"
