c# - Getting values from database in an item databound -


i looking solution following scenario using asp.net & sql server.

i have repeater control ,i need display image within repeater control , based on range of values stored in database table.

database table : level1 min   max 1      100   100 2      50     99 3      1      49

i used itemdatabound event repeater control. & hard coded min , max values . values database. 1 thing write stored procedure , call within item data bound event, concerned effect performance.

i know if there way min , max values database without effecting performance?

protected void rptmonitorsummary_onitemdatabound(object sender, repeateritemeventargs e)         {              if (e.item.itemtype == listitemtype.item || e.item.itemtype == listitemtype.alternatingitem)             {                  int x = convert.toint32(databinder.eval(e.item.dataitem, "x"));                 int y = convert.toint32(databinder.eval(e.item.dataitem, "y"));                  float percentage = (((float)x / (float)y)) * 100;                  if (percentage == 0)                 {                         ((image)e.item.findcontrol("btnperformanceimage")).imageurl = "../images/level1.png";                 }                  else if (percentage > 49 && percentage < 100 )                 {                         ((image)e.item.findcontrol("btnperformanceimage")).imageurl = "../images/level2.png";                 }                  else if (percentage > 1 && percentage < 49)                 {                         ((image)e.item.findcontrol("btnperformanceimage")).imageurl = "../images/level3.png";                 } }

i binding repeater in code :

rptsummary.datasource = getsummaryinfo(begintime.tostring(), endtime.tostring());             rptsummary.databind();

the getsummaryinfo method calls stored procedure performs calculation returns summary info x , y
