Customized Paging With Repeater And SQL

Question

I\'ve been looking for a good tutorial to teach me how to make a customized Paging control with a simple DataBound control like Repeater to implement a high performance pagi

Answer 1

You can create a custom method to render your own pagination control. Here is an example:

    /// <summary>
    /// Produces html for a pagination control.
    /// </summary>
    /// <param name="page">Page number for the current page (1-based index).</param>
    /// <param name="pageSize">Number or items per page.</param>
    /// <param name="totalItems">Total number of items across all pages.</param>
    /// <returns>Html of a pagination control.</returns>
    public string RenderPaginationControl(int page, int pageSize, int totalItems)
    {
        int totalPages = (int)Math.Ceiling((double)totalItems/pageSize);

        // Create pager.
        StringBuilder pagerSb = new StringBuilder();
        for (int i = 1; i <= totalPages; ++i)
        {
            // If it is NOT a link to current page.
            if (i != page) { pagerSb.Append(string.Format("<a href='/data.aspx?page={0}'>{0}</a>", i)); }
            // If it is the link to current page.
            else { pagerSb.Append(string.Format("<span>{0}</span>", i)); }
        }

        return pagerSb.ToString();
    }

As you can see apart from your sql, you will also need to call

SELECT COUNT(*) FROM Items

and pass that value to totalItems in the RenderPaginationControl.

And as far as the binding to Repeater is concerned - it's pretty straight forward:

this.MyRepeater.DataSource = DAL.GetItems(page, pageSize);
this.MyRepeater.DataBind();

int totalItems = DAL.GetTotalNumberOfItems();
this.PaginationLabel.Text = RenderPaginationControl(page, pageSize, totalItems);
