Hi guys,

I am working on checkboxes with listview.

I have given a checkbox on all rows of my listview control.
On submit I want to get all those rows whose checkboxes are selected.

This is my code.

protected void btnsavetofolders_Click(object sender, EventArgs e)
    {

  
            foreach (ListViewDataItem item in LstViewAppbyjob.Items)
            {
                CheckBox checkslct = item.FindControl("checkslct") as CheckBox;
              if (checkslct != null)
                {
                    if (checkslct.Checked)
                   {
                    Label lblprofileid = item.FindControl("lblprofileid") as Label;
                    if (Session["EmployerId"] != null)
                    {
                        JPosted.EmployerId = Convert.ToInt16(Session["EmployerId"]);
                        JPosted.intProfileId = Convert.ToInt16(lblprofileid.Text);
                        JPosted.JobPostedId = Convert.ToInt16(Request.QueryString["JobPostedId"]);
                        if (DdlFolders.SelectedIndex == 0)
                        {
                            JPosted.intFolderId = 0;
                        }
                        else
                        {
                            //JS.intFolderId = Convert.ToInt16(DSShowEmpFolders.Tables[0].Rows[0]["FolderId"]);
                            JPosted.intFolderId = Convert.ToInt32(DdlFolders.SelectedValue);
                        }
                        int CountSave;
                        CountSave = JPosted.InsertIntoSavedProfileInEmpFolders();
                        if (CountSave > 1)
                        {
                            lblmsg.Text = "This profile Already exist in your folder";
                        }
                        else
                            lblmsg.Text = "This profile has been successfully saved to your folder";
                    }
                }

                }
