推荐答案

protected void GridView1_PreRender(object sender, EventArgs e)
 {

     if (Session["page" + GridView1.PageIndex] != null)
     {
         int count = Convert.ToInt32(ViewState["total"]);
         CheckBox chb;
         bool[] values = (bool[])Session["page" + GridView1.PageIndex];

         for (int i = 0; i < GridView1.Rows.Count; i++)
         {
             chb = (CheckBox)GridView1.Rows[i].FindControl("chkStatus");

             chb.Checked = values[i];

         }

     }
 }

protected void GridView1_PageIndexChanging（object sender，GridViewPageEventArgs e）

{





Response.Write（GridView1.PageIndex.ToString（））;

int d = GridView1.PageCount;

bool [] values = new bool [GridView1.PageSize];



CheckBox chb;

int count = Convert。 ToInt32（ViewState [total]）;

for（int i = 0; i< GridView1.Rows.Count; i ++）

{

chb =（CheckBox）GridView1.Rows [i] .FindControl（chkStatus）;



if（chb！ = null）

{

values [i] = chb.Checked;

count ++;

}

}

会话[page+ GridView1.PageI ndex] =值;











GridView1.PageIndex = e.NewPageIndex;

DataTable dtPagination =（（DataTable）Session [details]）;

DataView dvPagination = new DataView（dtPagination） ;

GridView1.DataSource = dtPagination;

GridView1.DataBind（）;



}





i使用这两个事件我可以查看分页中的复选框但我想知道我用分页控件检查了整体gridview的复选框有多少.....

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{


Response.Write(GridView1.PageIndex.ToString());
int d = GridView1.PageCount;
bool[] values = new bool[GridView1.PageSize];

CheckBox chb;
int count = Convert.ToInt32(ViewState["total"]);
for (int i = 0; i < GridView1.Rows.Count; i++)
{
chb = (CheckBox)GridView1.Rows[i].FindControl("chkStatus");

if (chb != null)
{
values[i] = chb.Checked;
count++;
}
}
Session["page" + GridView1.PageIndex] = values;





GridView1.PageIndex = e.NewPageIndex;
DataTable dtPagination = ((DataTable)Session["details"]);
DataView dvPagination = new DataView(dtPagination);
GridView1.DataSource = dtPagination;
GridView1.DataBind();

}


i have use these two events i can check the checkbox in the paging but i want to know how many check boxes i have checked overall gridview with paging control.....

维护一个检查到会话变量的复选框计数器。对于每个选中和未选中的复选框，应更新此会话变量。



编辑：



在checkbox_checked服务器端的事件，更新会话变量中维护的计数器。选中未选中的每个复选框都会触发此事件。

Maintain a counter of checkboxes checked into a session variable. This session variable should be updated for every checkbox checked and unchecked.



On the checkbox_checked event on server side , update the counter maintained in the session variable. This event is fired on every checkbox checked-unchecked.
