        {
string Breaktype1= popgvdetails.Rows[j].Cells[6].Text;
CheckBox checklist = (CheckBox)popgvdetails.Rows[i].FindControl("popcheck");
 if (checklist.Checked == true)
            {

for (int j = 0; j < rowcount - 1; j++)
                {
 if (i != j)
                    {
string Breaktype2 = popgvdetails.Rows[j].Cells[6].Text;

                        if (Breaktype1 == Breaktype2)
                        {
                            ClientScript.RegisterStartupScript(this.GetType(), "disExp", "<script> alert('You have select the same Break Type');</script>");
                        }
                        j++;
}<pre lang="c#">

}

推荐答案

现在，我给出一些代码，如下所示：

Now,I give some code ,as follows :

protected void Button1_Click(object sender, EventArgs e)
       {
           int count = 0;
           string items = "";
           foreach (GridViewRow item in GridView1.Rows)
           {
               CheckBox cb = (CheckBox)item.FindControl("CheckBox2");
               if (cb.Checked)
               {
                   items = items + item.Cells[1].Text;//
                   count++;
               }
           }
           Response.Write(count.ToString() + items);
       }
