i am passing a query string with response.redirect, it is going to the page and checking the query string value in if condition , but if condition is returning false even though needed value is there in query string

my code :

response.redirect("2.aspx?rid=6")

on ther other side the if condition is as below
if(request.querystring("rid")="6")

{

}

while debugging when i take this query string in to quick watch it is showing as "6 "

but the if condition is failing : if(request.querystring("rid")="6")

You have tagged your question in C# and your requirement is in VB.NET, first update your question.

vb.net

VB

Dim query as Integer =Convert.ToInteger(Request.QueryString("rid"))
       if query=6 than
           //do your stuff
       else
           //do your stuff
       end

c#

C#

if (Request.QueryString.Count > 0) {

    int Query = Convert.ToInt32(Request.QueryString["rid"]);
    if (Query == 6)
    {
        //Do your stuff
    }
    else {
        //Do your stuff
    }
}

Modify this code according to your need.

Solution 1

If you're using C#, the code should be:

C#

request.querystring["rid"].Equals("6");

my code is in vb .net , can you please suggest this in vb.net

venky1988 11-Aug-14 21:50pm

this if condition is working fine with the initial request , but when i am trying to do a input button reset_onclick to load all initial values for this , it failing in if condition

Trung Nguyen Son 11-Aug-14 21:57pm

I think it's just your logic problem. Plz double check it!

Trung Nguyen Son 11-Aug-14 22:06pm

The "if condition" is in the page load event, right? Or in the button click event?

venky1988 11-Aug-14 23:01pm

the if condition is in a method which is called in page load ...

Trung Nguyen Son 11-Aug-14 23:05pm

just wrap it in:
If Not Page.IsPostback Then
'bla bla
End If

or in C#:
if (!Page.IsPostBack)
{
//bla bla
}

venky1988 11-Aug-14 23:41pm

Just to know... why we need to check if not post back

venky1988 11-Aug-14 23:52pm

It Is checking if cond. And failing so do you think if not post back causing issue

Trung Nguyen Son 11-Aug-14 23:57pm

I don't think it may the cause, plz post the whole code. I will look on it!

venky1988 12-Aug-14 1:00am

input type="reset" name="btnReset" value="Reset" onclick="javascript:location.href='selectedreport.aspx?rid=<%=request.querystring("rid")%> &name=<%=request.querystring("name")%>';" />

in page load()
If Not IsPostBack = True Then

RefreshPage()

in the RefreshPage()

If (Request.QueryString("rid") = "6") Then

tblcenterorderhistory.Visible = True

venky1988 12-Aug-14 1:57am

this error is because of space before 2nd query string id , so now this is working fine , my sincere thanks to Trung Nguyen Son and Nirav Prabtan
. and this is i am working in vb

Trung Nguyen Son 12-Aug-14 2:05am

Nice to hear that!

Happy coding!

venky1988 12-Aug-14 5:57am

Thank you

The "If Not Page.IsPostBack" code block is executed when the page
is loaded for the first time.
This is used to set the initial values for controls in the page.
When the page loads for a postback, you don't want to initialise the controls as you want them to get their values from the data that the user posted.

P/s: I think you should read more on web model!

Trung Nguyen Son 11-Aug-14 21:51pm

It looks like C#. Hehee
Your code in vb.net here: request.querystring("rid").Equals("6")
