Datatable dt1=new Datatable();
dt1=TempAdsDS.Tables[0];
string filter = ""Price > " + Minimum + " and Price < " + Maximum";

DataView view = new DataView(dt1);
view.RowFilter = filter;
dt1 = view.ToTable();

Hi,

First check you "Price" column data type it should be numeric (Int,Decimal,Float,Double) otherwise it will not show the proper values.

Apart from that keeping dataset in session/ViewState is not a good idea, so you can write data set in file and store it in some local temp path to uniform your file name you can use Session Id.

[Update]

var tt= TempAdsDS.Tables[0].AsEnumerable().Where( p =&gt; p.Field<int>("Price")>=Minimum && p.Field<int>("Price")<=Maximum)

Thanks,
Suvabrata

Price column is int type only.... But still i can't get correct result....how can i solve this

If so Then i don't see any error in it.
Or you can try the same using Linq

var tt= TempAdsDS.Tables[0].AsEnumerable().Where( p => p.Field<int>("Price")>Maximum && p.Field<"Price">()

And the types of Minimum and Maximum?

In this case it should be numeric.

Please refer to update section of my answer for proper LINQ.
