How to change RadSideDrawer MainContent

[kostas]

I am kind of new in xaml and Telerik controls.

I am using RadSideDrawer for my ContentPage.Content.

I would like to change RadSideDrawer MainContent on a button Click.

this is my code:

var incidentButton = new Button
            {
                Text = "Incident Button",
                WidthRequest=30
            };

            incidentButton.Clicked += OnIncidentButtonClicked;

            var aboutButton = new Button
            {
                Text = "About Button",
                WidthRequest = 30
            };

            aboutButton.Clicked += OnAboutButtonClicked;

            var drawerContent = new StackLayout();
            drawerContent.Children.Add(new Button { Text="alfa"});
            drawerContent.Children.Add(new Button { Text = "beta" });

            var mainContent = new StackLayout();

            mainContent.Children.Add(incidentButton);
            mainContent.Children.Add(aboutButton);

            var sideDrawer = new RadSideDrawer
            {
                MainContent = mainContent,
                DrawerContent = drawerContent,
                DrawerLength = 200
            };
            Content = sideDrawer;



            void OnIncidentButtonClicked(object sender, EventArgs e)
            {
                //Here i would like to change the sideDrawer.MainContent to another Content

            }

 

any suggestions?

Hello Kostas,

I've written you a demo (find it attached). When you click a button in the DrawerContent, it updates the MainContent.

Here's the code that performs the update:

private void SetMainContent(string contentType)
{
    switch (contentType)
    {
        case "Mail":
            drawer.MainContent = new MyMailView();
            break;
        case "Calendar":
            drawer.MainContent = new MyCalendarView();
            break;
    }
}

The key takeaway is the MainContent needs to be set using a type of View.

From what it looks like you're trying to do, just create your content (Grid/stackLayout/etc) first, and when it's done then set the SideDrawer.MainContent with it. 

I don't see anywhere you set MySideDrawer.MainContent = XXXX, change your approach to what you see in my demo and it should work as expected.
