Question

I am using the Repeater control. I can have around 300 records maximum.

I donot want to use Paging. There can be a provision to show More records with the help of More button at the bottom of Repeater.

Do you have any sample like that demonstrates such usage?

Answer 1

As the commenter says you do need paging

You would need to use the PagedDataSource as the data source for the repeater. This link shows how. Because the repeater doesn’t offer any ‘out of the box’ paging control you are free to code up whatever paging control you want – in your case the more button. From the link the databind would be something like

pagedDataSource page = new PagedDataSource();
            page.AllowCustomPaging = true;
            page.AllowPaging = true;
            page.DataSource = query;
            page.PageSize = 10;
            Repeater1.DataSource = page;
            Repeater1.DataBind();

Your paging might be something linq

protected btnMoreClick(object sender, EventArgs e)
{
    //.. get the source
    var dataSource = GetDataSource()

    //.. page it - i.e. use link
    dataSource.Skip(currentPage * pageSize).Take(pageSize)

    //.. now bind the source again
    //.. your code

}

Please note the above is pseudocode just to give you the idea and get you started.

I posted a previous answer about efficient paging which I think would be relevant in your case.

Hope this helps
