Paging Problems with repeater controls

Pagination | control | Problems before the time to do ASP is not short, but do asp.net I am a novice. A few days ago to do the project, encountered a problem, requiring more complex data format display, with a DataGrid is very difficult to achieve, and later used the Repeater control to achieve. But this brings up a new problem: How to page pagination? Repeater does not have a built-in paging capability. Later, I tried to write one, I was lucky to succeed. Hastily written on, certainly imperfect, which Master has any ideas please correct, very willing to communicate with you (zhoubin@mail.sdu.edu.cn)

Protected System.Web.UI.WebControls.Repeater Rptframework



private void Page_Load (object sender, System.EventArgs e)
{



Set up a dataset
(this part is omitted)

Rptframework.datasource = myDataSet;
Rptframework.databind ();

session["Page" = 1;





Hide all entries in the Repeater
int i = 0;

for (i = 0; i < RptFramework.Items.Count; i++)
{
Rptframework.items[i]. Visible = false;
}



Page size of the Repeater control
int intpagesize = 10;






Rptframework control's current page index (1 start)
int intcurrentpageindex = 0;



if (request.querystring["page"] = = NULL | | Convert.ToInt32 (request.querystring["page"]) = = 0)
{
session["Page" = 1;
}
Else
{
session["Page" = Convert.ToInt32 (request.querystring["page"));
}

Intcurrentpageindex = Convert.ToInt32 (session["page");



Previous Page button mask
if (Convert.ToInt32 (session["page"]) = = 1)
{
btnpre.enabled = false;
}



Current cursor index of the Rptframework control (1 start)
int intcurrentitemindex = 1;
Intcurrentitemindex = Intpagesize * (intCurrentPageIndex-1) + 1;



Next Page button mask
if ((Rptframework.items.count-intcurrentitemindex) < intpagesize)
{
btnnext.enabled = false;
}




Set the default view when a form is loaded
if (RptFramework.Items.Count > Intpagesize)
{
for (i = Intcurrentitemindex i < getmin (RptFramework.Items.Count, Intcurrentitemindex + intpagesize); i++)
{
RPTFRAMEWORK.ITEMS[I-1]. Visible = true;
}


}



}




Take the smaller value of two values, but do not change the original value size
private int Getmin (int a, int b)
{
int C;
if (a > B)
{
c = b;
}
Else
{
c = A;
}
return C;
}



Click on the previous page button
private void Btnpre_click (object sender, System.EventArgs e)
{

int intprepageindex = 2;

if (Convert.ToInt32 (session["page"))!= 1)
{
Intprepageindex = Convert.ToInt32 (session["page")-1;
}
Else
{
Intprepageindex = 1;
}

Response.Redirect ("jggk.aspx?page=" + intprepageindex.tostring ());
}



Click on the next page button
private void Btnnext_click (object sender, System.EventArgs e)
{
int intnextpageindex = Convert.ToInt32 (session["page"]) + 1;
Response.Redirect ("jggk.aspx?page=" + intnextpageindex.tostring ());
}
