C#

protected void next1_Click(object sender, EventArgs e)
    {
        if (inc != Maxrows)
        {
            inc++;
            Records();
            Label2.Text = inc.ToString();
            inc++;
        }
    }

I wish to use the above code so as to output the next record but it it only executes once. How can I go about it?

You will want to use a for loop or a foreach loop. I see that you are attempting to use an incrementer, but an if statement does not work like that. An if statement can be executed several times inside a loop, but does not act as a loop itself.

What are you trying to display, so I can get an idea.

Is it like a product database?

You click next and to to the next single product?

When you click next, an update panel makes a request for new html, and get updated without a full page request, or is it a full page request?

You should use a while/do while loop in order to sort this out.Also the code you have given is always displays the result in the same label.So you need to change that.In order to check the condition number of times you have to use any loop inside that.

Hi,

Did you check the values of the "inc" and "Maxrows" when you are trying to execute more than once. Is your 'if' condition satisfied ?

Solution 5

This is a sample example for displaying values in loop..

C#

int a = 5;
       while (a < 10)
       {
           ListBox1.Items.Add(Convert.ToString(a));
           a++;
       }
