Hello Liu Yan,

You can check out the following code to access the value of a CheckBox on clicking a button outside the grid.
cs:

 protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid2.MasterTableView.Items)
        {
            foreach (GridColumn col in RadGrid2.MasterTableView.RenderColumns)
            {
                if (col.UniqueName == "ToandFro")
                {
                    CheckBox chkbx = (CheckBox)item["ToandFro"].Controls[0];
                    string strtxt = chkbx.Checked.ToString();
                }
            }
        }
    }

Hello Liu Yan,

You can try out the code snippet given below and see if it meets your requirement.
aspx:

<telerik:GridClientSelectColumn UniqueName="SelectCol"></telerik:GridClientSelectColumn>

cs:

 protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridItem item in RadGrid2.SelectedItems)
        {
            GridDataItem dataitem = (GridDataItem)item;
            CheckBox chkbx = (CheckBox)dataitem["SelectCol"].Controls[0];

        }
    }

Thanks
Shinu.

Hi, this is my C# code
 
   protected void BtnUnlock_Click(object sender, EventArgs e)
    {  
        if (HiddenField1.Value != "")
        {
// if using Microsoft Grid,the code can get Checkbox value
//bool bIsLocked = ((CheckBox)GridView1.Rows[GridView1.SelectedIndex].Cells[9].Controls[0]).Checked;           
// Error code: get checkbox value(datatyp: bit)
            bool bIsLocked = ((CheckBox)RadGrid1.Rows[RadGrid1.SelectedIndex].Cells[5].Controls[0]).Checked;
            if (bIsLocked)  //Locked
            {
                MembershipUser u;
                string strUserName = this.RadGrid1.SelectedValue.ToString();
                u = Membership.GetUser(strUserName);
                string connstring = ConfigurationManager.ConnectionStrings["CBPCConnectionString"].ConnectionString;
                using (SqlConnection dataConnection = new SqlConnection(connstring))
                {
                    dataConnection.Open();
                    SqlCommand dataCommand = new SqlCommand("aspnet_Membership_UnlockUser");
                    dataCommand.Connection = dataConnection;
                    dataCommand.CommandType = CommandType.StoredProcedure;
                    dataCommand.Parameters.Add(new SqlParameter("@ApplicationName", SqlDbType.NVarChar));
                    dataCommand.Parameters.Add(new SqlParameter("@UserName", SqlDbType.NVarChar));
                    dataCommand.Parameters[0].Value = "CBPC";
                    dataCommand.Parameters[1].Value = strUserName;
                    SqlDataReader reader = dataCommand.ExecuteReader();
                    reader.Close();
                    dataConnection.Close();
                }
                //this.RadGrid1.DataSource = SqlDataSource1;
                this.RadGrid1.Rebind();
                //发送邮件
                MailMessage m_message = new MailMessage();
                m_message.From = new MailAddress("[e-mail]");
                m_message.To.Add(new MailAddress(u.Email));
                m_message.Subject = "From P-VCIS";
                string MailBody = "Hi，" + strUserName + "\r\n:";
                MailBody = MailBody + "Your account has been unlocked .";
                m_message.Body = MailBody;
                SmtpClient m_smtpClient = new SmtpClient();
                m_smtpClient.Send(m_message);

            }
        }
        else
        {
            this.Label2.Text = "No Selecting!";
        }
    }

Hi Liu Yan,

Here I have tried with a CheckBox in the ItemTemplate of a GridTemplateColumn. On clicking the Button I am trying to access the CheckBox from the selected rows of the Grid.

CS:

  protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridItem item in RadGrid1.SelectedItems)
        {
            GridDataItem dataitem=(GridDataItem)item;
            CheckBox chkbx = (CheckBox)dataitem["CheckCol1"].FindControl("CheckBox1");
            bool BoolVal = chkbx.Checked;
        }
    }

ASPX:

<telerik:GridTemplateColumn UniqueName="CheckCol1"  HeaderText="CheckCol1" >
                       <ItemTemplate>
                           <asp:CheckBox ID="CheckBox1" runat="server"  Checked='<%#Eval("CheckCol1") %>'/>
                       </ItemTemplate>
                    </telerik:GridTemplateColumn>

Thanks
Princy.
