如何将数据集平均分为两部分？

Question

I'm programming on Asp.net and C#.

I have a Dataset which is populated by records from database. On my design page, I have two Datagrids.

How can I equally divide the records inside the Dataset so they can be bound to two separate datagrids?

Answer 1

you can use DataView on your dataset and then bind your 2 Datagrids on dataview here a sample http://www.dotnetperls.com/dataview

work for instance to set one dataview on rows.count/2 and the other too

Answer 2

This works for me,

 var d=ds.Tables[0];// here ds is your dataset.
 int count=d.Rows.Count;
 var x=new DataTable();
 for(int i=0;i<=count;i++)
 {
   var dr=d.Rows[i];   
   x.Rows.Add(dr.ItemArray);
   d.Rows.RemoveAt(i); 
 } 
 var ret=new DataSet();
 ret.Tables.Add(x);
 ret.Tables.Add(d);

so now you have dataset that contain two equal datatable.
