  DataAdaptor don't return values in foreach

  May 31, 2009 01:11 PM|LINK

   Hello,

  I have a strange situation:

  It's work just fine when I do this:

  gridView.dataSource=myAdaptor.getdata(a,b);

  gridView.databind();

   

  but when I want to to this:

  foreach(string s in listOfStrings)

  {

  gridView.dataSource=myAdaptor.getdata(s,b);

  gridView.databind();

  if(gridView.rows.count!=0)

  {

  ...do somethnig    //never enter in if clauses
  

  }
  

  }

  nothing return. 

  My need is to see what string from listOfString return some value, and to use it forward, but nothing return 0 counts.

  listOfStrings contain sure one value that should return something. I do something wrong here?
  

  All the best,

  hi..

  i think you have to do something like this..

  foreach(string s in listOfStrings)

  {

  gridView.dataSource=myAdaptor.getdata(s,b);

  gridView.databind();

  if(gridView.rows.count!=0)

  {

  ...do somethnig    //never enter in if clauses
  

  }

  break; 

  }

  hope this helps..

  Debug your codes, set a break point where you assign the DataSource for your GridView and check whether your Adaptor returns any data.

  If it won't go to the line  if(gridView.rows.count!=0), then that means there no data returned from your Adaptor query...
