Solution 1

You are referencing a variable (ids) that doesn't exist in your btndetails_Click procedure. Where is that value meant to be coming from? Fix that and it will be sorted.

C#

string ids="";
protected void btndetails_Click(object sender, EventArgs e)
{
Response.Redirect("product_details.aspx?ids=" + ids);
}

You have to assign the value for ids variable..

The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Solution 3

be sure that ids is defined and it's scope is available in Button_click event & has some value in it.

for example regarding Query strings refer:
