Call .cs method/function from .ascx

[trullock]

Hi,

Is there a way to call a codebehind method/function from an attribute
of a runat=server tag, kinda like this:

<asp:Literal runat="server" ID="litTest" Text='<%#
MyMethod("testargs") %>' />

but obviously that doesn't work

Thanks

1) Make sure MyMethod returns a string

2) Make sure MyMethod has either protected or public scope

3) Change <%# to <%=

I prefer to put the code in the code behind:

litTest.Text = MyMethod("testargs");

Hi,

I tried that but it just literally writes out: <%=
MyMethod("testargs") %> into the resultant html.



Goran, I cant do that for a complicated reason that i wont rabble on
about here. I just need to be able to do it from the html, not the
codebehind.

Any other ideas anyone?

Thanks

Does this work:?

<asplaceHolder ID="litTest"
runat="server"><%=MyMethod("testargs")%></asplaceHolder>

This should work, if you just call litTest.DataBind() in code when you want
it to be "called". <%# refers to a databinding expression when something
must call DataBind() for the control for databinding to occur.

Does this work:?

<asplaceHolder ID="litTest"
runat="server"><%=MyMethod("testargs")%></asplaceHolder>

'System.Web.UI.WebControls.Literal' does not allow child controls.

Hi, Yeah i know i can call databind and use a # in the server tags,
but i want to avoid any codebehind. (if im calling databind i might as
well just do literal.text = "value";

Thanks for the suggestion anyway

Once again - does this work:?

<asplaceHolder ID="litTest"
runat="server"><%=MyMethod("testargs")%></asplaceHolder>

Please read carefully...

You can also do it on the aspx side if you use <script
runat="server">...</script> block, no need to touch the code-behind ;-)

My bad, sorry.

Yeah that works, but when i try and do it in an attribute it doesnt

Thanks

Yup,

because <%= %> is resolved when the Page is rendered, so it's target cannot
be server-side property (which basically such attribute represents on server
control)

Why do you have to put it in a Literal control? Just do:

<%=MyMethod("testargs")%>
