Accessing input values across user controls
-
I have an ASP.NET page with a form that contains two user controls:
<%@ Register TagPrefix="x" TagName="c1" Src="ctl1.ascx" %> <%@ Register TagPrefix="x" TagName="c2" Src="ctl2.ascx" %> <body> <form runat="Server"> <x:c1 id="con1" runat="Server"> <x:c2 id="con2" runat="Server"> <form> </body>In one control (
con1) I have a dropdownlist. In the other control (con2), I have a set of textboxes that I would like to pre-populate with values that depend on what item is selected in the dropdownlist in the first control. How can the code forcon2access the value of the dropdownlist incon1? Thanks for any help or suggestions. -----G -

u must public the dropdownlist for your form and use it. for example: public DropDownList drop1 { get{return yourdropdownlistid;} } and use con1.drop1.SelectedItem in your form code -------------------------------------------------------- or define a dropdownlist in con2 for example: private DropDownList DropDownList1; public DropDownList con1dropdownList { get{return this.DropDownList1;} set{DropDownList1 = value;} } and in form use from: con2.con1dropdownList = con1.drop1; We Can Do Anything, If We Want It
Well, that isn't right, because the crux of the problem is I'm working within the code-behind page of a user control, not the main page. As a result, I don't have direct accss to con2 or con1 as properties. So I can't use, for example "con1.drop1.SelectedItem", because it will say "con1 not defined". And if I try something like "Page.con1.drop1.SelectedItem" it will say that con1 is not a property of Page. I actually found my answer, though, just FYI: I needed to use the Page.FindControl() method, which solved my problem.
