how to get a control ID from a bind field name / bound field (column) name from a formview's control

I have a form view which is bound to a table, now from codebehind file I need to apply some formatting based on some of the field's bound control. For example, if Formview1 is bound to Employee table, and it's item template has a control with ID "Label1" which is bound to "EmployeeJoinDate" . Now, I have a different table which has a list of field name(EmployeeJoinDate is one of them), all of which should be applied some formatting based on some condition.

Now I can take two approach for that, but I am stuck at both:

 1. If I can somehow get the control ID which is bound on a particular column(eg, find the control that bounds to "EmployeeJoinDate"), I can easily apply the formatting. But I couldn't find anywhere how to do it.

2. I can iterate through all the controls in formview using FormView.Controls collection and check if it is bound to any of the field in the ConditionalFieldList, then apply the formatting. But I don't know how to find the bound field name of any control.

 Any clue? I would prefer any solution to the approach 1, as in that case I only have to iterate through only those fields, where the condition will be applied, Not all the controls inside the formview. But if it's not possible suggestion to approach 2 will also be appreciated.

Here you go... this is pretty common... you will use FindControl...

in the Page_PreRender use this code and then do your formatting there also:

Dim Label1 As New System.Web.UI.WebControls.Label

Label1 = CType(gridbill.Rows(x).FindControl("Label1"), System.Web.UI.WebControls.Label)

Well you can do this  in the databound event of your formview where you have to search for your control.

Something like this:


Label lbl = (Label)FormView1.FindControl("Label1");

lbl.Id = here you can get the id you want.

Maybe I was not clear enough. I know how can I get access to a webcontrol using FindControl method. But for this I need to know the Server ID of the control. But the thing is I don't know which ID the control has, I only know the bound field name(EmployeeID), using this name I want to find the controlthat is bound to this field(in this case Label1) .

Naming a document element problems (trying to getElementByID() but the id's of the control are staring with _'s, which are not valid)
This page is an almost working implementation of viewing the HTML source, you'll see the two files are very close, with the difference being that the spans in the working on faulty version are named "_ctl0_Strategy0" instead of "Strategy0".

How to control field names?

The table Part has got some relationships with the User table (created by, changed by, ...).
