what is the .net framework version you are using?
what is the column data type of todate in your database table?
can't you change the select sql statement of GetTaxdetails method to return data maching your condition?

here, you need to write this condition in SQL query or SP from which you get datatable.
Pass date parameter in query or sql so you will get result depending on your condition. and then bind result set to grid.

You haven't answer to my comments, below code will work for .net 3.5 + with LINQ

C#

DataTable dtbind = new DataTable();
dtbind = objvehicleBAL.GetTaxdetails();
dtbind = dtbind.AsEnumerable()
    .Where(r=>DateTime.ParseExact(r.Field<string>("todate"), "dd/MM/yyyy", null) < DateTime.Now.AddDays(15))
    .CopyToDataTable();
GVTax.DataSource = dtbind;
GVTax.DataBind();

you can use r.Field<DateTime>("todate") <DateTime.Now.AddDays(15) if you have datetime column.

Hello ,
You can use LINQ. Try this way

ateTime dt=DateTime.Now.AddDays(15);//first take one DateTime variable and set the value  

//make the Where condition in your DataTable 
var newdatasource = dtbind.Where(x => t.todate.Date < dt).ToList();

//now set the new DataSource to gridview
 GVTax.DataSource = newdatasource
 GVTax.DataBind();

thanks

Update your query in GetTaxDetails so that it does not return rows that fail the IF.

create dataview using datatable and filter row into dataview then convert it to table and bind that table to gridview

C#

DataTable dtbind = new DataTable();
           dtbind = objvehicleBAL.GetTaxdetails();
           DataView dv = new DataView(dtbind);
           dv.RowFilter = "Date = #12/02/2014#";


               GVTax.DataSource = dv.ToTable();
               GVTax.DataBind();

I had solved my problem using this modifications in my code

C#

dttableNew  = dttableOld.Clone();

            foreach (DataRow drtableOld in dttableOld.Rows)
            {
               if (/*put some Condition */)
               {
                  dtTableNew.ImportRow(drtableOld);
               }
            }

            GVTax.DataSource = dtTableNew;

           GVTax.DataBind();
