Question

我似乎无法更改页脚文本。我也尝试了排序事件，但没有任何反应。我想要做的就是显示状态消息。这是我的代码：

protected void PageSettings_Sorting(object sender, GridViewSortEventArgs e)
{
  if (((GridView)sender).EditIndex > -1)
  {
    e.Cancel = true;
  }
  else
  {
    // tried this on sorted aswell but can't change footer text
    GridViewRow row = ((GridView)sender).FooterRow as GridViewRow;
    Label lblStatus = new Label{ ID="lblStatus", Text="Sorting Column <b>\"" + e.SortExpression + "\" " + e.SortDirection + "</b>"};
    row.Cells[0].Text = "Hello World"; //.Controls.Add(lblStatus);            
  }
}

protected void PageSettings_RowCreated(object sender, GridViewRowEventArgs e)
{
  if (e.Row != null && e.Row.RowType == DataControlRowType.Header)
  {

  }
  else if (e.Row != null && e.Row.RowType == DataControlRowType.Footer)
  {
    int count = e.Row.Cells.Count;
    for (int i = count - 1; i >= 1; i += -1)
    {
      e.Row.Cells.RemoveAt(i);
    }
    e.Row.Cells[0].ColumnSpan = count;
    e.Row.Cells[0].Controls.Add(new Literal { ID = "lblStatus" });
    // can't FindControl or change Literals either
    e.Row.Cells[0].Text = "Hello World"; // works here but not on sorting event
  }        
}

这将更改第一个FooterRow单元格的文本：

protected void gv_Sorting(object sender, GridViewSortEventArgs e)
{
    gv.FooterRow.Cells[0].Text = "Hello";
}

当然，您需要确保GridView的{{1}}属性为真。

或者，通过转换发件人并添加控件：

ShowFooter

在GridView中更改页脚文本
