ASP.NET Tricks

Problem
You know it’s possible to have controls with the same name on one page. In this case Request.Form[”txtSomeText”] returns the values form all 5 textboxes comma separted. (For example: text1,text2, text3.text4, text5).

Example:

.....

<input type="text" name="txtSomeText" />
<input type="text" name="txtSomeText" />
<input type="text" name="txtSomeText" />
<input type="text" name="txtSomeText" />
<input type="text" name="txtSomeText" />

.......

The question iin this case is “How to get the values for each textbox?”.
You can say “I’ll split the values…” but it’s not a good solution. What if one of the values is “text,text,text”?

I spent a lot of time splitting strings and searching for workaround of “comma values” (a,b,c) until I found the solution. Here it is..

Solution:
It’s simple: Request.Form returns NameValueCollection. GetValues is a NameValueCollection class method which gives us the requested result.

Request.Form.GetValues(”txtSomeText”) returns a string array with all the values.
