A ASP.NET MVC page with multiple instances of user control consuming the independent data.

Question

First let me thank all of you for numerous useful posts I have read during my recent ASP.NET MVC development. My questions is as follows:

I have a ASP.NET MVC application with loosely coupled model, meaning I use a business layer assembly in a controller to access the data and return data to a view by setting Viewdata["MyData"] from the controller.

Now my question is how to set individual data of a user control which has multiple instances in a MVC page.

Eg. I have a text box inside userctl.ascx as:

<%= Html.TextBox("ApprovalDate", ViewData["ApprovalDate"],
                 new { @ReadOnly = "True" })%>

If i set ViewData["ApprovalDate"] to be something, how does it apply to individual control data?

Appreciate your help.

Answer 1

In your case it would work if you set your user controls (partial views in MVC terminology) to be strongly typed.

Then you can initialize the model and pass it to each individual partial view without those values getting mixed up.

Of course, you need to pass to the view the data for all hosted controls in some form.
