MonoTouch is 5.2.12. iOS is v5.1.1 (Simulator)
Seems like I'm missing an important piece of a puzzle here.
I'm subclassing DialogViewController and set it as the only controller in my UINavigationController.
In ViewWillAppear of the subclassed DialogViewController, I'm trying to set the left and right bar button items:
this.NavigationController.NavigationItem.LeftBarButtonItem = new UIBarButtonItem(UIBarButtonSystemItem.Done, this.HandleDoneButtonTouched );
Neither one of them is showing up. The title however is displayed. If I debug, I can see that the items are properly set.
I have also tried to use SetItems() on the navigation controller: no effects either.
The navigation controller is presented modally in a page sheet.
Navigation items are not usually updated through the navigation controller. Instead, they are updated via the NavigationItem property on the view controller:
this.NavigationItem.SetRightBarButtonItem(
new UIBarButtonItem(UIImage.FromFile("some_image.png")
, UIBarButtonItemStyle.Plain
, (sender,args) => {
// button was clicked
})
, true);

I am using below tutorial to create image check box
enter link description here
it works properly but once page post back it lose the checked element and cannot retrieve it .
is there any solution for this issue?
This is absolute normal if you not save the post back somewhere and then render again the controls with the one that is selected with that class active, the rest controls with out that class...
See the javascript code from your page:
$(function () {
$('.btn-radio').click(function(e) {
$('.btn-radio').not(this).removeClass('active')
.siblings('input').prop('checked',false)
.siblings('.img-radio').css('opacity','0.5');
$(this).addClass('active')
.siblings('input').prop('checked',true)
.siblings('.img-radio').css('opacity','1');
});
});
The selected have the active class !, so after the post back, save the user selection and render the selected control with that class.
Just getting to grips with this cool framework and interested in adding in an extra feature into the default toolbar. I assume the toolbar is from the following:
#Edit.Toolbar(Content)
And the functions from which each item is defined is in the 'inpage.js' file which houses all the menu item actions (add, new, replace). But when I try the following (inside in 'image max 3.cshtml'):
#Edit.Toolbar(Content, actions: "edit,replace,color");
and have a new colour action created in 'inpage.js':
'color': {
title: "Toolbar.Sort",
iclass: "icon-sxc-table",
showOn: "edit",
addCondition: function (settings, modConfig) { return modConfig.isList && settings.useModuleList && settings.sortOrder !== -1; }
},
This however is not presenting anything to the screen for me. I assume I am missing something but my aim was to replicate the reorder feature action but instead have a modal popup colour palette in order to change the colour of the background of each indivudal 'Image(s) max 3. in a row' content type views.
Appreciate any and all help!
Thx
2sxc 08.06 is out, and allows this now. Check out the 2sxc-wiki https://github.com/2sic/2sxc/wiki/Html-Js-Command-Custom-Code
I have a simple WebView application. In one of the cases, I show a file, to allow user go back a UINavigationBar is shown:
navigationBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 20, 320, 44)];
navigationItem = [[UINavigationItem alloc] init];
navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Back"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(buttonClicked:)];;
[navigationBar pushNavigationItem:navigationItem animated:YES];
[self.view addSubview:navigationBar];
This is working nice. It shows a back button, and when back button is clicked it executes selector (button style must be improved, but I'm newbie with xCode and c# and this will come later).
In the selector i load previous url, but I can't figure out how to hide button and bar.
- (IBAction) buttonClicked:(id)sender {
return [self.webView loadRequest:[[NSURLRequest alloc] initWithURL:[NSURL URLWithString: lastURL]]];
}
I've tried several things, like removeFromSuperView:
[navigationBar removeFromSuperview];
Hide it:
[self.navigationController setNavigationBarHidden:YES animated:YES];
self.navigationController.navigationBar.hidden = YES;
// or
[navigationItem hidesBackButton];
// or
navigationBar.hidden = TRUE;
Using the selector (id):
[sender show:NO];
Using the alpha property:
navigationBar.alpha = 0,0;
Free memory space:
navigationItem.dealloc;
But nothing works... I think I'm missing some important detail, because I don't know really how xCode works...
Any help will be appreciated!
Personally, I would never add a navigation bar like that, but rather have a root navigation controller, which has a root view controller that holds a webview as it's view.
You did not make it very clear, how do you actually show the file?
Anyway, this code:
[self.navigationController setNavigationBarHidden:YES animated:YES];
is not working for you because you haven't provided your view controller with a navigation controller.
Provide one, maybe best in the main storyboard, and setup your view controller (that holds the webview) as its root view controller. To do that, open the storyboard, and drag/drop a UINavigationController to the main area. You have to tick the option "Is Initial View Controller". Note: when you did the drag/drop, a default root view controller was already provided. You can either leave that one, or provide your own, if you already had one in the storyboard. To do that, delete the linked one, and ctrl-click and drag from the Navigation Controller to the View Controller, to setup it as its Root View Controller. I've attached an image to showcase what I've described.
please forgive the newness level I'll be exhibiting.
I created a new iPad Master/Detail (UISplitViewController) app in Monotouch.
The master controller on the left is a UITableViewController. The detail on the right is just a UIViewConroller. These are loaded by default in the AppDelegate code.
In the master controller I then added some items to the table and overrode the RowSelected() event and that works great, so I can get the item selected. I've added an additional UIViewController (DetailViewController2) that I want to display on the right side of the screen when an item is selected in the table. It really doesn't matter which item, I just want to change the contents of the right side where the DetailViewController is to the DetailViewController2. I've tried a lot of things and nothing working -- I know this should be obvious, but I'm lost.
Thanks for any help.
If you are using UISplitViewController, the way to change the master and detail controller is to update the ViewControllers property. It always wants both, the master and the detail controller.
If you want to update the detail only, your code would be something like this:
var masterController = splitController.ViewControllers[0];
var newDetailController = new DetailViewController2();
splitController.ViewControllers = new UIViewController[] { masterController, newDetailController };

I encountered some weird behaviour today and I was hoping someone could shed some light on it for me because I'm perplexed.
I have a couple of methods I use to interact with the ui for the sole purpose of displaying error/success/warning messages to the user.
Here is one of them
public static void Confirm(string text)
{
var page = (Page)HttpContext.Current.Handler;
var uiConfirm = new HtmlGenericControl("div")
{
ID = "uiNotify",
InnerHtml = text
};
uiConfirm.Attributes.Add("class", "ui-confirm");
page.Master.FindControl("form1").Controls.AddAt(2, uiConfirm);
}
This works perfectly fine except for one nuance I encountered this morning and I was hoping someone could shed some light on it for me.
I am working on your run of the mill profile editing page. In this page, I am binding a couple of dropdownlists (country, province/state) on page load. I have a submit at the bottom and a click event that fires to update the information, then call the method above to notify the user that their information was successfully updated. This works the first time you click the submit button; the page posts back, the information gets updated in the database, the dynamically added div gets popped in, confirm message is displayed and all is good. However, if you then click the submit button again, it fails stating SelectedItem on the dropdowns I'm binding in the page load is null (Object reference not set to an instance of an object). The dropdown is actually wiped for some reason on the second postback, but not the first.
In sheer desperation after trying everything else, I decided to take out the call to the confirm method... and strangely enough the error disappears and I can update the information on the page as many times as I like.
If I add a generic control statically to the page I'm working on, and change my method slightly so that instead of adding a generic control to the form dynamically it just finds the generic control on the page, that does no produce the same error.
The problem also goes away if I remove the two dropdowns from the page or just stop interacting with them.
Why on earth would adding a dynamic control to the form wipe my dropdowns on postback?
I think you should consider using the PlaceHolder class in your MasterPage, the AddAt(2, uiConfirm) is going to bite you and probably is:
Markup:
.......
<asp:PlaceHolder id="PlaceHolder1"
runat="server"/>
......
Code-behind:
public static void Confirm(string text)
{
var page = (Page)HttpContext.Current.Handler;
var uiConfirm = new HtmlGenericControl("div")
{
ID = "uiNotify",
InnerHtml = text
};
uiConfirm.Attributes.Add("class", "ui-confirm");
//may need to change depending on where you put your placeholder
Control placeHolder = page.Master.FindControl("PlaceHolder1");
placeHolder.Controls.Clear();
placeHolder.Controls.Add(uiConfirm);
}
