Why HyperLink control don't get url?

Question

I use a HyperLink control in my page

<asp:HyperLink runat="server" ID="btn_add_Task" Text="Create New Task" CssClass="dnnPrimaryAction"></asp:HyperLink>

In code behinde set it url

 protected void On_Load(object sender, EventArgs e)
        {
            base.OnLoad(e);

            btn_add_Task.NavigateUrl = ModuleContext.EditUrl("Edit");
        }

But When build and run, it don't have any url in properties.

Answer 1

In order for the EditUrl("Edit") to work, you need to make sure you have a module view with the controlkey that matches "Edit". Here is what that looks like in your .dnn manifest file for installing the module:

<moduleControl>
    <controlKey>Edit</controlKey>
    <controlSrc>DesktopModules/MyModule/Edit.ascx</controlSrc>
    <controlType>Edit</controlType>
    ...
</moduleControl>

And it should look like this in Host > Extensions > [Edit you Extension] > Module Definitions:

Notice I have a control with "Edit" key that maps to my Edit.ascx view
