How to Execute/Evaluate String in Asp.Net 1.1 using Vb.Net ?

[Kamal Ahmed]

Hi all,
I want to execute a String that is generated at Runtime and fills data in
DropDownList Controls at Runtime. I want to do this at server side. As Eval
functions works as client side function and there is not other function or
command to do this
example is here..
("ddlSub" & CStr(nRow) & ".DataSource = dtrSubject")
I want to evaluate this string to get name of control at runtime e.g.
ddlSub1, ddlSub2, ddlSub3 and so on

How it will be done using Asp.Net 1.1 using Vb.Net ?

TIA

You can do a Page.FindControl("CONTROL_ID");

note though that this isn't a recursive find (like client-side
getElementById()

for example, say the control you wanted was inside a placeholder:
<asplaceholder id="plc" runat="server">
<asp:dropdownlist id="ddl" runat="server">
</asplaceholder>

rather, you'll need to eitehr nest them:
Page.FindControl("plc").FindControl("ddl")

or base it off the parent control:
ddlontrol.FindControl("ddl")


of course, if the control isn't nested, you can just do
Page.FindControl("ControlId") and ignore everything I said except the first
line (Which is the same as this line!!)

Eval is a server side function. it is evaluated and executed in the server.
