The QueryString values are read only you can't clear the values, so have redirect to same page to clear the values.

hi prabhu,

You can yous namevalueCollection in asp.net

Just create an object on namevalueCollection which contains a query string and now object.remove("What ever values you want");

Thanks and Regards

Hi Prabhu

As Saratchand suggest, that's the only option you can use to clear Query String Parameters. See Below

// Get the NameValueCollection
PropertyInfo isreadonly = typeof(System.Collections.Specialized.NameValueCollection).GetProperty("IsReadOnly", BindingFlags.Instance | BindingFlags.NonPublic);
// make collection editable
isreadonly.SetValue(this.Request.QueryString, false, null);
// remove
this.Request.QueryString.Remove("YourQueryStringParameter");

Don't forget to add following Using Statement

using System.Collections;
using System.Reflection;

I know you asked this question in December Last year and by now you may have solved the issue, but this will be helpful for other users.

Thanks
Happy Coding
