protected void Button2_Click(object sender, EventArgs e) { String imid = DropDownList3.Text.ToString(); int imageid = Convert.ToInt32(imid); String lid = DropDownList4.Text.ToString();

I have a detailsview with template fields. when i go into edit mode i am trying to set the selectedvalue of a dropdownlist to be the value of the corresponding label from the item template in code behind as once i go into edit mode i loose the initial value from the detailsview and the dropdownlist defaults to the first listitem. what i am doing is onDataBinding of the detailsview i access the cell value of the label , i then assign that to a public variable but once i've exited the routine the public variable looses the value of the detailsview cell i've just assigned to it. this is the value i'm hoping to assign to the selectedvalue of the dropdownlist when i go into editmode. The reason i'm doing it this way is although i can use bind in the html to mantain the dropdownlist selected value between detailsview states once i come to update the detailview i get the following error
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.to work arround this i've had to assign the values to update paramteres also in code behind. here's my code behind page i've bolded the routines in question. drpDataStoreDDL is the variable in question.

Basically the scenario is like this, I'm getting an XML from a 3rd party application with available dates for booking, for each day there are types of rooms the person can choose, single, double, etc.
Each hostel will return me an unknown number of room types. But dont get too confused with this. The thing is simple I just need to add an unknown number of dropdownlists (or HTML Select) with the numbers of persons to book for. Now because I don't know how many of those dropdowns I will have I need to add them programatically inside a "for int i=0; i
How can I add an unknownn number of dropdownlists programatically to a page and retrieve the selected values with c# on submit?The last column on the screenshot

Update:I'm creating the code from the xml results as a string that will print as html code:
I know that doing that and adding the runat=server won't help on my control, there is where my main problem is now, how to add the code on the html to be able to get the dropdownlist selected value later with c#. Can I do that with Request.Form ? was trying but so far I couldnt do it.
