I'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.

View 2 RepliesActually I am wishing to use StringBuilder to Append DataTable as given below:
[Code]....
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?).
Im developing a web application in asp.net where i have gridview with some text box controls in it.In runtime we are creating a new row dynamically by clicking add button .To insert data into the database.i used a stringbuilder instead of string becoz the data what i have to insert into database is more.but i am gettin the following error No mapping exists from object type System.Text.StringBuilder to a known managed provider native type. in database the datafield column datatype is varchar(max).

i have a stringbuilder which loops thru the items details of my shopping cart like below:
StringBuilder sbo = new StringBuilder();
for (int i = 0; i != Cart.Order.Items.Length; ++i)
{
sbo.AppendLine(
string.Format(
"{0} {1} {2} {3} <br />",
Cart.Order.Items[i].ItemNumber,
Cart.Order.Items[i].ProductTitle,
Cart.Order.Items[i].Size,
Cart.Order.Items[i].Price.ToString("c")
)
);
}
now i would like to bind these details to 4 labels like lbItemno, lbProdTitle, lbSize, lbPrice.
i 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.

I 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?
