How To Pull Values From A QueryString / Add/Multiply Them And Then Write To A Label
May 5, 2010
I'm at the end of a project and have hit a wall. I'm pretty unfamiliar with VB so this is why I've left this piece of the project for last.
I have a popup window in which I pass some values via QueryString. I want to be able to pull them into my application and do some math on them and then write them out to my aspx page. The problem is I don't know where/how to begin. I've searched around the asp.net boards, but can't seem to find any good starting point.
I'm reading in some dollar amounts, a percentage and an Id that I'll use to pull a payment schedule (number of payments). I'm trying to get at a payment breakdown. I was thinking of writing it Something like this:
I've got a formview that does a simple 'SubTotal' calculation based on some checkbox inputs. I write out the subtotal to an asp:label control. I want to be able to also be able to write that value into the QueryString so I can carry it over to another page. I can't seem to access the label from my codebehind (intellisense doesn't find it). I assume I'm not making the correct reference to the formview label control, but I don't know how to go about getting at it.
I would like to multiply the values from two text boxes (txtBox1 should contain an Integer value, txtBox2 should contain a Float value) and place the result in a third text box. My code is below, but it doesn't work. The javascript function is called, otherwise it fails.
Is there a way to grab the querystring from the original request or pull it from the ASPX ErrorPath?
We've updated 5 applications, and combined them into one. However, when someone requests and old URL such as [URL]I tried capturing the value from the querystring, but it does not seem to work since the aspxerrorpath is there (404 page).
I have a dropdownlist which display the price of products which is retrive from database, how do i mulitply if the user entered the quantity in the textbox. I keep getting error input string was not in a correct format.
I have populated a gridview with the following code
string WhereClause = query; string OrderBY = "PostedOn desc"; int PageIndex = gvJobPosting.PageIndex; int PageSize = gvJobPosting.PageSize;
[Code]....
But on int PostID = JobID[0].JobPostingID; i'm getting the error NullReferenceException Object reference not set to an instance of an object how do I set this so it takes the jobpostingID out of the session and loads it into the variable so i can use it as the parameter to call teh stored procedure
Just for curiosity, i want to know i how many ways we can write the parameters in a querystring. I have encountered the following
& (is common that we use in our most of the application) , (in some banking application) ; (bank.co.in/BANKAWAYTRAN;jsessionid, this is from my banks QS :-) )
I want when I am search any another college then show my url
http://localhost:1682/FinalTest/searchcollege.aspx?CollegeId=20&id=3&cid=5 means only change my CollegeId=25 to 20 and other parameter is not change. Use only javascript.
