Hi,
Could you please let me know how to pass value from one page to other through Query String as I am new in ASP.NET.
Your help will be appreciated!

Thanks,
John

We pass the value from one page to another page by query string, we write the syntax as

1) Response.Redirect("Default.aspx?query=John Smith");

where "query" is query string variable and "John Smith" is the string value for query variable.
Now we access the value on Default.aspx page as

string query=Request.QueryString["query"].toString();

2) we pass the multiple parameter by query string then we write the syntax as

Response.Redirect("Default.aspx?query1=John Smith &query2=krish");

Now we access the value on Default.aspx page as

string query1=Request.QueryString["query1"].toString();
string query2=Request.QueryString["query2"].toString();

or
string query1=Request.QueryString[0].toString();
string query2=Request.QueryString[1].toString();

or
string query1=Request.Params[0].toString();
string query2=Request.Params[1].toString();

3) We pass the any value by query string as

string str="JohnSmith";
Response.Redirect("Default.aspx?query="+str);

And access these value on another page by

string query=Request.QueryString["query"].toString();

If you want to pass value from one page to another using Query string then just add name of query followed by its value.

example

supose you have two pages a.aspx and b.aspx and you want to pass value from a.aspx to b.aspx then instead of just redirecting to page b.aspx, redirect to b.aspx as b.aspx?Name=Haider

Here Name is name of Query String and Haider is value you want to pass.

Now to access this value in b.aspx use

string strName = Request.QueryString["Name"].toString();

thx for your time ..:)
