Question

我的GridView填充了某个过滤条件。

我有PageIndexChanging个事件来执行我的数据分页。

protected void gvPeople_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    lblAddError.Text = String.Empty;
    List<People> list = (List<People>)ViewState[_vsPeopleList];
    gvPeople.DataSource = list;
    gvPeople.PageIndex = e.NewPageIndex;
    gvPeople.EditIndex = -1;
    gvPeople.DataBind();
}

之后，我在不更改过滤条件的情况下执行Search。

protected void btnPeopleSearch_Click(object sender, CommandEventArgs e)
{
    if(e.CommandName.Equals("Search"))
    {
        PopulatePeople();
    }
}

private void PopulatePeople()
{
    lblAddError.Text = String.Empty;
    if (ViewState["_message"] != null)
    {
        lblAddError.Visible = true;
        lblAddError.Text = ViewState["_message"].ToString();
    }
    ViewState["_message"] = null;

    int portfolio = int.Parse(ddlPortfolio.SelectedItem.Value);
    ViewState["portfolioID"] = portfolio;
    string year = ddlYear.SelectedItem.Text;
    string month = ddlMonth.SelectedItem.Text;

    List<People> list = People.GetPeople(portfolio, year, month);
    ViewState[_vsPeopleList] = list;
    if(list.Count == 0)
    {
        gvPeople.Visible = false;
        lblAddError.Visible = true;
        lblAddError.Text = "No data available for current selection";
    }
    else
    {
        gvPeople.Visible = true;
        gvPeople.DataSource = list;
        gvPeople.DataBind();
    }
}

我应该像在分页到下一页之前那样获得GridView中的所有数据。但是，我的页面不会刷新以显示所有数据，它只显示该页面索引的数据，但是，我的列表计数等于从数据库填充的记录数。此外，如果我更改搜索过滤器，则会正确显示数据。

我做错了什么？

看起来gvHolidays_PageIndexChanging事件与其他网格相关，因为其中编写的代码适用于网格gvPeople。

如果没有，请尝试以下操作。

//Write the following code inside gridviews PageIndexChanging event.
gvPeople.PageIndex = e.NewPageIndex;
gvPeople.EditIndex = -1;
gvPeople.SelectedIndex = -1;

//Write the following code inside gvHolidays_PageIndexChanged event.
lblAddError.Text = String.Empty;
List<People> list = (List<People>)ViewState[_vsPeopleList];
gvPeople.DataSource = list;
gvPeople.DataBind();

分页后GridVIew不刷新
