Let's say user has selected chk1,chk2,chk3,chk4 and chk5 then you want to display the 1st chk1.value and last selected chk.value. Am I right?

Please help.

tell me one thing. What if user select chk1,chk2,chk6 then what to display on label.

Hi,
Do you want label to show in comma separated sequence or Min Value and Max Value of selected Check boxes ?
EX : 1,2,3,4 or 1-4 ???

Is that so then what if user select check box 3,5,8,6 ?? what do you expect in thi s scenario ??

Member239258 8-Jan-15 2:12am

Dear Praveen it should display in label as 1-6 like this

Member239258 8-Jan-15 2:13am

Mr Sumit Jawale, No Comma Separated values...it should display in label as 1-6 like this

Sumit Jawale 8-Jan-15 2:26am

dont you think will be wrong ?? If user selected only three text box 1,3,6 then it will show 1-6. As per my understanding it is wrong. Beacause 1-6 means 1 to 6 (in other words user selected all checkbox from 1 to 6 ) .
please clarify your exact need.

Please find the code block below.

XML

<asp:Button Text="Click Me" ID="btn" runat="server" OnClick="btn_Click" />
            <asp:Panel ID="Panel1" runat="server">
            <asp:CheckBox Text="1" runat="server" ID="chk1" />
            <asp:CheckBox Text="2" runat="server" ID="chk2" />
            <asp:CheckBox Text="3" runat="server" ID="chk3" />
            <asp:CheckBox Text="4" runat="server" ID="chk4" />
            <asp:CheckBox Text="5" runat="server" ID="chk5" />
            <asp:CheckBox Text="6" runat="server" ID="chk6" />
            <asp:CheckBox Text="7" runat="server" ID="chk7" />
            <asp:CheckBox Text="8" runat="server" ID="chk8" />
            <asp:CheckBox Text="9" runat="server" ID="chk9" />
            <asp:CheckBox Text="10" runat="server" ID="chk10" />
            </asp:Panel>
            <asp:Label Text="" ID="lbl" runat="server" />

Below is the code behind

C#

protected void btn_Click(object sender, EventArgs e)
        {
            List<int> values = new List<int>();
            foreach (Control item in Panel1.Controls)
            {
                if (item.GetType().ToString().Equals("System.Web.UI.WebControls.CheckBox"))
                {
                    CheckBox c = (CheckBox)item;
                    if (c.Checked)
                        values.Add(Convert.ToInt16(c.Text));
                }
            }

            if (values.Count > 0)
            {
                values.Sort();
                lbl.Text = values[0] + " - " + values[values.Count - 1];
            }
        }
