.net Usercontrol Vs Customcontrol Vs Stringbuilder?
Dec 22, 2010I'm building a product catalog which displays between 50/100 products per page.Since I want to have different browse sections on my site I've put each product into a UserControl. Well, not the products themselves ofcourse, but some labels, divs and images. I then set its properties in run-time when processing the database results. So the advantage is that I only have to change the product control at 1 place for the whole site. I'm putting the controls in a page using LoadControl in a loop.
However the pages are not loading quite as fast as other pages which process the same db query and output the same html using a StringBuilder. And since I want my site to perform well if/when it receives some decent traffic I'm worried about this. I haven't done any benchmarkings yet but I clearly see the difference. My questions to you is 'Are there any alternatives which are faster then using LoadControl with a customcontrol but are easily maintained (or atleast in 1 location)?'I was thinking of:
Creating a customcontrol (although I've never done it and don't know 100% if this will speed things up)Continue with the StringBuilder method and put the CreateProduct in my base class
[edit]Code[/edit]
I don't have the excact usercontrol code here but I will edit this post when I get home..but here is the simplified idea:
1) Getting my database result (using Subsonic 2.2 as my DAL)
DAL.ProductCollection coll = new DAL.ProductCollection();
if(coll.count > 0)
{
foreach(DAL.Product item in coll)[code]....
My usercontrol itselves just consists of 3 Literal controls and 1 Image control.
ADO.NET :: StringBuilder Error - Append Datatable?
Nov 20, 2010Actually I am wishing to use StringBuilder to Append DataTable as given below:

correct the line sb.Append(dt.Rows[i].Item(k, DataRowVersion.Current).toString()); to eliminate the following error:
'System.Data.DataRow' does not contain a definition for 'Item' and no extension method 'Item' accepting a first argument of the type 'System.Data.DataRow' could be found (are you missing a using directive of an assembly reference?).

C# - Dynamically Create Controls Using Stringbuilder?
Mar 12, 2010i have been trying to create controls dynamically on my web page using the StringBuilder class..and i dont quite seem to get through...
i am trying to do this...
StringBuilder sbTest = new StringBuilder(string.Empty);
sbTest.Append("<input type="text" id="txt1" runat="server" />");
Response.Write(sbTest.ToString());
The page for sure displays a TextBox on the browser which is easily accessible through JavaScript...but what i want is the control to be available on the Server Side too...so that when the page is posted back to the server i can easliy obtain the value that has been entered by the user into the textbox.

Web Forms :: Use Stringbuilder When Concatenating More Than 2 Strings - Performance?
Jul 2, 2010I have been led to believe that the performance benefits of using StringBuilder over normal concatenation means that you should always use stringbuilder when concatenating more than 2 strings. However when I test them this does not seem to be the case. Take these 2 methods
public void TestMethod5()
{
for (int i = 0; i < 1000; i++)
{
string t = string.Empty;
t = "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd"; ;
}
}
public void TestMethod6()
{
for (int i = 0; i < 1000; i++)
{
StringBuilder sb = new StringBuilder();
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
string t = string.Empty;
t = sb.ToString();
}
}
TestMethod5 takes 0.03 milliseconds so complete but TestMethod6 takes 1.43 milliseconds What is going on?

View 8 RepliesC# - Is It A Good Practice To Write HTML Using A StringBuilder In Codebehind
Mar 25, 2010I'm interested to hear from other developers their opinion on an approach that I typically take. I have a web application, asp.net 2.0, c#.
What I usually do to write out drop downs, tables, input controls, etc. is in the code behind use StringBuilder and write out something like sb.Append("
I don't find myself using to many .net controls as I typically write out the html in the code behind. When I want to use jQuery or call JavaScript I just put that function call in my sb.Append tag like sb.Append("td...onblur='fnCallJS()'.
I've gotten pretty comfortable with this approach. For data access I use EntitySpaces.
I'm just kind of curious if this sort of approach is horribly wrong, ok depending on the context, good, time to learn 3.0, etc. I'm interested in learning and was just looking for some input.
Edit
After reading the comments here it sounds like I should take a look at MVC. I've not done that yet. The only hesitancy in doing so is that the existing project is just that, existing. There is a lot of code already done the way I explained and it is hard to imagine what would be involved in changing it, advantages of doing so, and just learning what that would take.
The other thing I'm taking away from the comments is that my code behind should really not include much of the sb.Append code, whereas now it is filled with it in numerous functions. To me it is not messy but that is because I know what each function does and can look at it and see, oh that writes out x, y, and z.
It's not uncommon for me to just have a div on the .aspx part and then build up the .innerHtml of that with the StringBuilder in the code behind.
