Question

我有代码在它执行if else循环以检查某些数据后会出现一个动态按钮。

但是，gridview无法进行任何分页。它只显示第一页，不能转到第二页，依此类推。它只能进行寻呼IF i nvr调用下面的方法。

这是我的代码

 public void filter_select(object sender, GridViewRowEventArgs e)
{ 
 if (e.Row.RowType == DataControlRowType.DataRow)
    {
     ........                
            }

该方法将在rowdatabound gridview页面源上调用，如OnRowDataBound="filter_select"

源代码上的gridview代码是：

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" CellPadding="2" CellSpacing="2" 
     HorizontalAlign="Center" OnRowCommand="stop_survey" 
       OnRowDataBound="filter_select" OnSelectedIndexChanging="selected" PageSize="5" 
    Width="133%" DataKeyNames="SurveyID" DataSourceID="SqlDataSource1" AutoGenerateColumns="False" 
        >
          <Columns>

                                    <asp:BoundField DataField="SurveyID" HeaderText="Survey ID" ReadOnly="True" 
                                    .........

我的onrowCommand代码

 public void stop_survey(object sender, GridViewCommandEventArgs e)
{
    SqlConnection con;
    string sqlcom;
    SqlCommand cmd;

    //is it because of this code below? as if i comment from this code onwards, the paging works.
    GridViewRow row = (GridViewRow)((Button)e.CommandSource).NamingContainer;
    Button btn = (Button)GridView1.Rows[row.RowIndex].FindControl("btnStop");
    ...............

在gridview控件的PageIndexChanging事件中重新绑定gridview

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

无法在gridview asp.net上进行分页，
