.NET Forum / ASP.NET / General / August 2007Call .cs method/function from .ascx
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 Andrew > Is there a way to call a codebehind method/function from an attribute > of a runat=server tag, kinda like this: [quoted text clipped - 3 lines] > > but obviously that doesn't work :( 1) Make sure MyMethod returns a string 2) Make sure MyMethod has either protected or public scope 3) Change <%# to <%=  SignatureMark Rae ASP.NET MVP http://www.markrae.net > <trull...@googlemail.com> wrote in message > [quoted text clipped - 17 lines] > Mark Rae > ASP.NET MVPhttp://www.markrae.net 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:? <asp:PlaceHolder ID="litTest" runat="server"><%=MyMethod("testargs")%></asp:PlaceHolder> SignatureMark Rae ASP.NET MVP http://www.markrae.net > <trull...@googlemail.com> wrote in message > [quoted text clipped - 8 lines] > Mark Rae > ASP.NET MVPhttp://www.markrae.net 'System.Web.UI.WebControls.Literal' does not allow child controls. :( Andrew >> Does this work:? >> [quoted text clipped - 6 lines] > > 'System.Web.UI.WebControls.Literal' does not allow child controls. Once again - does this work:? <asp:PlaceHolder ID="litTest" runat="server"><%=MyMethod("testargs")%></asp:PlaceHolder> Please read carefully...

Yeah that works, but when i try and do it in an attribute it doesnt :( Thanks Andrew 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) SignatureTeemu Keiski AspInsider, ASP.NET MVP http://blogs.aspadvice.com/joteke http://teemukeiski.net >> <trull...@googlemail.com> wrote in message >> [quoted text clipped - 29 lines] > > Andrew >> <trull...@googlemail.com> wrote in message >> [quoted text clipped - 25 lines] > > Andrew Why do you have to put it in a Literal control? Just do: <%=MyMethod("testargs")%> SignatureGöran Andersson _____ http://www.guffa.com > Hi, > [quoted text clipped - 9 lines] > > Andrew I prefer to put the code in the code behind: litTest.Text = MyMethod("testargs"); SignatureGöran Andersson _____ http://www.guffa.com 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.

(if im calling databind i might as well just do literal.text = "value"; Thanks for the suggestion anyway :) You can also do it on the aspx side if you use <script runat="server">...</script> block, no need to touch the code-behind ;-) SignatureTeemu Keiski AspInsider, ASP.NET MVP http://blogs.aspadvice.com/joteke http://teemukeiski.net >> This should work, if you just call litTest.DataBind() in code when you >> want [quoted text clipped - 29 lines] > > Thanks for the suggestion anyway :) Free MagazinesGet these publications absolutely FREE for up to 12 months.
