当我更改页码时，出现错误

"The GridView 'GridView1' fired event PageIndexChanging which wasn't handled."

但之后，我搜索并尝试将此代码放入 PageIndexChanging 中，但它仍然无法正常工作：

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.SelectedIndex = e.NewPageIndex;
    GridView1.DataSource = SqlDataSource1;
    GridView1.DataBind();
}

最初，当用户提示页面时，我在 gridview 上显示所有数据，然后用户可以搜索数据，然后单击搜索按钮，执行以下代码：

 protected void Button1_Click(object sender, EventArgs e)
{
    DateTime dt1 = DateTime.Now, dt2 = DateTime.Now;
    Connection.getCon();
    try
    {
         dt1 = Convert.ToDateTime(TextBox3.Text);
         dt2 = Convert.ToDateTime(TextBox4.Text).AddDays(1);
        lblError.Visible = false;
    }
    catch (Exception exc) {
        lblError.Visible = true;
    }


    string cmd = "select * from tblLogs where (users like '%"+TextBox1.Text.Trim()+"%') and (request like '%"+TextBox2.Text.Trim()+"%') and (requesttime>='"+dt1+"') and (requesttime<'"+dt2+"') ";
    SqlDataSource1.SelectCommand = cmd;
    DataView dv= (DataView) SqlDataSource1.Select(DataSourceSelectArguments.Empty);
    GridView1.DataSourceID = null;
    GridView1.DataSource= dv;
    GridView1.DataBind();
    //GridView1.AllowPaging = false;

}

现在，我没有收到任何错误，但页面仍然没有改变并保持在 1。

谢谢。

您在 PageIndexChanging 事件中使用了错误的属性，它应该是PageIndex而不是 SelectedIndex：

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    GridView1.DataSource = SqlDataSource1;
    GridView1.DataBind();
}
