How to change the value of textbox without posting page back to the server
I have a simple form with 3 textboxes namely txtNumber1, txtNumber2, txtTotal.
The txtTotal will display the sum of txtNumber1 and txtNumber2. I'd like when the user enter a number either in txtNumber1 or txtNumber2 the txtTotal will automatically update its value without posting page back to the server. Do I need to utilize Ajax to accomplish it?
Thanks for reading.
There are couple of options you can use:
1] Use Java Script to Populate your txtTotal on change of text in txtNumber1 / txtNumber2

I am using VS.net to create an asp.net application. In one of my "pages", I have the SQL Select Command that VS generated for me, and I have added a couple of lines to pass through a querystring variable into the query.
It works great, however VS.net keeps deleting my additions and reverting back to the original query. Any way to prevent this?
Don't put your changes in that method. VS.NET overwrites that method whenever it wants to.
You can create your own method, and make a call to that method right after the base.OnInit call in (I think, I don't have ASP.NET at work si...Changing "Web Form Designer Generated Code" and it Changes back!
I created a SQL connection using VS.net's built in tools for doing so. I'm calling a stored procedure to which I am trying to pass a variable (the contents of a querystring).
I have the code for this written in the SQLSelectCommand1 area, but the problem is vs.net keeps changing the code back to the way it wrote it. My way works, VS doesn't, so I have to keep pasting my code changes back to the .vb file. Is there any way to make these changes stick?...Could PB .NET Web Form POST security Information to others web page??

How can i know if the "text" inside of a text box has changed?
For example, I currently have this:
But this does not work. The other idea I had was to assign the existing value of the text box to a string and then when the user click the save button I can create a conditional statement to compare the original string with the new string. However, I would like something more effective as I have like 12 text boxes to compare.

HiI have a formview in insert mode for inserting items into a gridview. Each item is some description text, a price, and a quantity.
