问题描述

我正试图在页面移动(分页)之前获取转发器项目的所有选中的转发器复选框，并将其存储在某个位置.

I am trying to get all repeater's selected checkboxes of repeater's item just before page movement (pagination), and store them in some place.

 foreach (RepeaterItem ri in rpt.Items)
  {
      CheckBox box = (CheckBox)ri.FindControl("chkBox");
       if (box.Checked)
       {
          ...
       }
  }

问题是我从哪里调用此函数?我试图从ObjectDataSource1_Selected(我使用objectdatasource来填充转发器)和ObjectDataSource1_Selecting中调用它，但是rpt.Items.Count也为0.

The problem is where do i call this function from?I've tried to call it from ObjectDataSource1_Selected (I use objectdatasource to populate repeater) and ObjectDataSource1_Selecting but rpt.Items.Count is also 0.

rpt_PreRender()事件，返回正确数量的项目，但它发生在选择复选框之前，而不是之后.

rpt_PreRender() event, returns the right number of items but it happens before the selection of checkboxes and not after.

我该怎么办?

        {
            CheckBox chk = (CheckBox)Repeater1.Items[count].FindControl("CheckBox1");
