Hi
I have a panel where there is a repeater with one textbox and a label.

When you insert a number in textbox and click on update button it will count all the value from the text box and show the calculated number in a label.

And when the calculated number is 7 then you can not insert any numbers in the textbox.

I have try this:
I dont know what i could do when the number is reach 7.

C#

<asp:Panel ID="Panel_visfrugt" runat="server">
        <table border="1">
            <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT * FROM [frugt]"></asp:SqlDataSource>
            <tr>
                <td>Antal</td>
                <td><asp:Label ID="Label1" runat="server" Text=""></asp:Label></td>
            </tr>
            <asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1" OnItemCommand="Repeater1_ItemCommand">
                <ItemTemplate>

            
            <tr>
                <td><%#Eval("frugt_navn") %></td>
                <td><asp:TextBox ID="txtbox1" runat="server" Width="30"></asp:TextBox></td>
            </tr>
            
    </ItemTemplate>
            </asp:Repeater>
        </table>
    </asp:Panel>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click1" />

C#

  protected void Page_Load(object sender, EventArgs e)
    {
       
        Panel_visfrugt.Visible = true;
        
       
    }


protected void Button1_Click1(object sender, EventArgs e)
    {
        foreach (RepeaterItem item in Repeater1.Items)
        {
            if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
            {
                TextBox Textbox_antal = item.FindControl("txtbox1") as TextBox;
                int antal = 0;

                int i = int.Parse(Textbox_antal.Text) + int.Parse(Textbox_antal.Text) + int.Parse(Textbox_antal.Text) + int.Parse(Textbox_antal.Text) + int.Parse(Textbox_antal.Text) + int.Parse(Textbox_antal.Text) + int.Parse(Textbox_antal.Text) + int.Parse(Textbox_antal.Text);

                if (antal != 7)
                {

                    Label1.Text = "Nu er der 7";
                
                }
               
                else
                {
                    Label1.Text = "Der er over 8 nu";
                }
               



            }

        } 
       
    }

Hi,
in this case you need to define a global variable to store the value on each time button clicked. try like this:

C#

private int Value = 0;
   protected void Page_Load(object sender, EventArgs e)
   {
       Panel_visfrugt.Visible = true;
   }

   protected void Button1_Click1(object sender, EventArgs e)
   {
       foreach (RepeaterItem item in Repeater1.Items)
       {
           if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
           {
               TextBox Textbox_antal = item.FindControl("txtbox1") as TextBox;

               Value = Convert.ToInt32(Value + int.Parse(Textbox_antal.Text));

               if (Value != 7)
               {
                   Label1.Text = "Nu er der 7";
               }
               else
               {
                   Label1.Text = "Der er over 8 nu";
               }
           }
       }
   }
