how to assign a control property value from a global variable in page code?

Question

Greetings,

I have a control and list of variables and I want in the control property to be assigned to the variable value directly in the page not from the back code, something like this

My global variables

public string Banana = "banana_pie";
public string Apple = "apple_pie";

in my custom control instead of:

<uc:LoadPie id="pieBanana" type="banana_pie" />

To this

<uc:LoadPie id="pieBanana" type="<%=Banana %>" />

so is there a way or just assign the property in page back code.

Thanks

Answer 1

I think you should go with a property (protected should be enought, but I'll say public in the following snippet) in your code behind:

Public Property myBanana() As String
   Get
      Return Pies.Banana;
   End Get
End Property

Then you can use it in your controls, for example:

<uc:LoadPie id="pieBanana" type="<%= myBanana%>" />

Answer 2

Not quite what you want, but how about:

<% pieBanana["type"] = this.Banana %>

Answer 3

You can do it like this using data binding syntax.

<uc:LoadPie id="pieBanana" type='<%#Banana%>' runat="server"></uc:LoadPie>

But then in your code behind you have to call

pieBanana.DataBind();

in the page load in order for the databinding expression to be evaulated.

But if you are going to do this then you might as well assign the property in the page load.
