hi，
我已使网格视图的选定行可见= false
此
用过的会话

hi ,
i have made the selected row of the grid view visible=false
used session for this

DataTable table = (DataTable)Session["CurrentData"];
       for (int i = GridView1.Rows.Count - 1; i >= 0; i--)
       {
           CheckBox chkbox = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("selector");
           if (chkbox.Checked)
           {
               GridView1.Rows[i].Visible = false;
           }

       }

这里的选择器是gridview复选框ID

here the selector is the gridview checkbox id

DataTable table = (DataTable)Session["CurrentData"];

for (int i = GridView1.Rows.Count - 1; i >= 0; i--)
        {

            CheckBox chkbox = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("selector");
            if (chkbox.Checked)
            {
                // GridView1.Rows[i].Visible = false;

                myDt.Rows.RemoveAt(i);
                DataTable myDt1 = (DataTable)Session["tabel"];
                GridView1.DataSource = myDt1;
                GridView1.DataBind();


            }
        }
