Pagination Help: How to create multiple pages.

[ironhide1975]

We're looking at some custom code for a page that displays search results. The code looks like it was created under an ASP.NET 1.1 structure. The following code creates the Previous/Next buttons and counts the results. Can someone help me create a Function to add the Page numbers in between these Previous/Next button.

protected void ShowResults(SearchResultItemCollection items, int nTotal, long nTimeUsed)
		{
			int nCount = 0;

			if(items != null)
			{
				nCount = items.Count;
			}

			Total = nTotal;
			//m_lblTotal.Text = string.Format("Found: {0} documents", nTotal);
			m_lblTotal.Text = string.Format("Results <strong>{0}</strong> to <strong>{1}</strong> of <strong>{2}</strong>", Offset + 1, Offset + nCount, Total);

			ShowButtons();

			if(nCount > 0)
			{
				m_dgResults.DataSource = items;
				m_dgResults.DataBind();
			}

			if(nTotal <= 0)
			{
				m_divSearchWithinResults.Visible = false;
				m_tblDrillDown.Visible = false;
				m_dgResults.Visible = false;
				m_lblNoResults.Visible = true;
				m_lblTotal.Visible = false;
			}
			else
			{
				m_divSearchWithinResults.Visible = true;
				m_tblDrillDown.Visible = true;
				m_dgResults.Visible = true;
				m_lblNoResults.Visible = false;
				m_lblTotal.Visible = true;
			}
		}

		protected void ShowButtons()
		{
			if(Total > Hits)
			{
				m_btnNext.Visible = true;
				m_btnNext2.Visible = true;
			}
			
			if((Offset + Hits) >= Total)
			{
				m_btnNext.Visible = false;
				m_btnNext2.Visible = false;
			}
			else
			{
				m_btnNext.Visible = true;
				m_btnNext2.Visible = true;

				int n = Total - (Offset + Hits);
				if(n < Hits)
				{
					m_btnNext.Text = string.Format("next {0} >>", n);
					m_btnNext2.Text = string.Format("next {0} >>", n);
				}
				else
				{
					m_btnNext.Text = string.Format("next {0} >>", Hits);
					m_btnNext2.Text = string.Format("next {0} >>", Hits);
				}
			}


			if(Offset > 0)
			{
				m_btnPrev.Visible = true;
				m_btnPrev2.Visible = true;

				if(Offset > Hits)
				{
					m_btnPrev.Text = string.Format("<< previous {0}", Hits);
					m_btnPrev2.Text = string.Format("<< previous {0}", Hits);
				}
				else
				{
					m_btnPrev.Text = string.Format("<< previous {0}", Offset);
					m_btnPrev2.Text = string.Format("<< previous {0}", Offset);
				}
			}
			else
			{
				m_btnPrev.Visible = false;
				m_btnPrev2.Visible = false;
			}
		}

It looks as though your code uses the "items.Count" value to work out how many items there are. If that is correct you can divide that by the number of records per "page" to work out how many pages there are and then add a control for each page number.

Hi,

Well I've just been through this myself but in VB I'm afraid ~ I blogged about it here..

I used a repeater for the numbers.

Copy that code into Telerik's

Hope this helps,
