从下面的非解决方案复制的其他信息

我试图打印出所有选中的复选框



我的gridview正在选择，我把它更改为复选框现在它不工作





这是旧代码选择的是什么：

 受保护  void  Page_Load（ object  sender，EventArgs e）
 {
  if （！Page.IsPostBack）
会话[  AreaId ] = -1; 
} 
 
 受保护  void  ButtonPrint_Click（ object  sender，EventArgs e）
 {
  try  
 {
 Session [   FromURL] =  〜/报告/ SpaceUtilised.aspx; 
 
会话[  ReportName] =   Spaceused; 
 
 Microsoft.Reporting.WebForms.ReportParameter [] RptParameters =  new  Microsoft.Reporting.WebForms.ReportParameter [ 5 ]; 
 
  //  创建ConnectionString报告参数 
  string  strReportConnectionString = Session [  ReportConnectionString]。ToString （）; 
 RptParameters [ 0 ] =  new  Microsoft.Reporting.WebForms.ReportParameter（  ConnectionString，strReportConnectionString）; 
 
  //  创建WarehouseId报告参数 
 RptParameters [< span class =code-digit> 1 ] =  new  Microsoft.Reporting.WebForms.ReportParameter（   WarehouseId，会话[  WarehouseId ]的ToString（））; 
 
  //  创建AreaId报告参数 
 RptParameters [< span class =code-digit> 2 ] =  new  Microsoft.Reporting.WebForms.ReportParameter（   AreaId，会话[  AreaId ]的ToString（））; 
 
 RptParameters [ 3 ] =  new  Microsoft.Reporting.WebForms.ReportParameter（   ServerName，会话[ < span class =code-string> ServerName]。ToString（））; 
 
 RptParameters [ 4 ] =  new  Microsoft.Reporting.WebForms.ReportParameter（   DatabaseName，会话[ < span class =code-string> DatabaseName]。ToString（））; 
 
会话[  ReportParameters] = RptParameters; 
 
 Response.Redirect（ 〜/ Reports / Report.aspx） ; 
} 
  catch  {} 
} 
 
  protected   void  CheckBoxAll_OnCheckedChanged（ object  sender，EventArgs e）
 {
  if （CheckBoxAll.Checked）
 {
 Session [  AreaId] = -1; 
 AreaSearch1.Visible =  false ; 
} 
  else  
 AreaSearch1.Visible =  true ; 
} 

然后我不得不将其更改为复选框，因为我希望能够选择多行

Im trying to print out all selected checkbox

My gridview was selecting and I changed it to checkbox now its not working


THIS WAS THE OLD CODE WHICH WAS SELECTING:

protected void Page_Load(object sender, EventArgs e)
{
   if(!Page.IsPostBack)
      Session["AreaId"] = -1;
}

protected void ButtonPrint_Click(object sender, EventArgs e)
{
   try
   {
      Session["FromURL"] = "~/Reports/SpaceUtilised.aspx";

      Session["ReportName"] = "Space Utilised";

      Microsoft.Reporting.WebForms.ReportParameter[] RptParameters = new Microsoft.Reporting.WebForms.ReportParameter[5];

      // Create the ConnectionString report parameter
      string strReportConnectionString = Session["ReportConnectionString"].ToString();
      RptParameters[0] = new Microsoft.Reporting.WebForms.ReportParameter("ConnectionString", strReportConnectionString);

      // Create the WarehouseId report parameter
      RptParameters[1] = new Microsoft.Reporting.WebForms.ReportParameter("WarehouseId", Session["WarehouseId"].ToString());

      // Create the AreaId report parameter
      RptParameters[2] = new Microsoft.Reporting.WebForms.ReportParameter("AreaId", Session["AreaId"].ToString());

      RptParameters[3] = new Microsoft.Reporting.WebForms.ReportParameter("ServerName", Session["ServerName"].ToString());

      RptParameters[4] = new Microsoft.Reporting.WebForms.ReportParameter("DatabaseName", Session["DatabaseName"].ToString());

      Session["ReportParameters"] = RptParameters;

      Response.Redirect("~/Reports/Report.aspx");
   }
   catch { }
}

protected void CheckBoxAll_OnCheckedChanged(object sender, EventArgs e)
{
   if (CheckBoxAll.Checked)
   {
      Session["AreaId"] = -1;
      AreaSearch1.Visible = false;
   }
   else
      AreaSearch1.Visible = true;
}

Then I had to change it to checkbox because I want to be able to select multiple rows
