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) & ".DataSourc e = 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.FindContro l("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:
<asp:placeholde r id="plc" runat="server">
<asp:dropdownli st id="ddl" runat="server">
</asp:placeholder >

rather, you'll need to eitehr nest them:
Page.FindContro l("plc").FindCo ntrol("ddl")

or base it off the parent control:
ddlontrol.FindC ontrol("ddl")
of course, if the control isn't nested, you can just do
Page.FindContro l("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.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
