I have an element with a Click method.
I would like to activate that method (or: fake a click on this element) within another function.
Is this possible?
No, there currently isnt a way to do this. See links:

windows phone 7: How to simulate control click programmatically
EDIT
This doesnt do exactly what you wanted to do, but you can do something like this and get the same outcome. I do this type of pattern alot in my code to do get the same outcome.
XAML
<Button Name="testClick" Click="testClick_Click">
<TextBlock Text="Click Me"></TextBlock>
</Button>
C#
private void testClick_Click(object sender, RoutedEventArgs e)
{
TestFunction(sender as Button);
}
private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
//Call same function as button
TestFunction(testClick);
}
private void TestFunction(Button bt)
{
//do stuff
}
Somewhere in your class initiate a RoutedEventArgs:
private RoutedEventArgs evnt;
Then later call this:
element_Click(element, evnt);
That should do it.

If you ever remove focus from any professional application like Chrome/FireFox/Visual Studio, and then reclick a button/menu item, it will actually click it as if you never lost focus.
How can I apply the same concept in C# WinForm? I tried many things like
private void form1_MouseClick(object sender, MouseEventArgs e)
{
BringToFront();
Activate();
}
Activate/focus/select/etc... nothing worked to react the same way, it always takes 3-4 clicks to actually click on a menu!
I thought about making a click event for every single control, but that seemed rather redundant.
Check this for example (Yellow Clicks)
You are right about Menues taking an extra click to get focus.
Which is extra annoying since the menue get highlighted anyway but doesn't react to the 1st click..
You can avoid that by coding the MouseEnter event:
private void menuStrip1_MouseEnter(object sender, EventArgs e)
{
// either
menuStrip1.Focus();
// or
this.Focus();
}
The downside of this is, that it is stealing focus from other applications, which is not something a well-behaved application should do..
So I think it is better to wait for a definitive user action; code the MouseDown event in a similar way..:
private void menuStrip1_MouseDown(object sender, MouseEventArgs e)
{
menuStrip1.Focus();
}
Or use the event that was made for the occasion:
private void menuStrip1_MenuActivate(object sender, EventArgs e)
{
menuStrip1.Focus();
}
I can't confirm a similar problem with Buttons or any other controls, though.
I have find trick to solve your problem. it work for me 100%
See this code:
dynamic elem1;
private void menuStrip1_MouseEnter(object sender, EventArgs e)
{
elem1 = sender;
}
private void menuStrip1_MouseLeave(object sender, EventArgs e)
{
elem1 = null;
}
private void Form1_Activated(object sender, EventArgs e)
{
if(elem1 != null){
elem1.PerformClick();
if (elem1.GetType().ToString() == "System.Windows.Forms.ToolStripMenuItem") elem1.ShowDropDown();
}
elem1 = null;
}
Here what happend.
When mouse enter button/menu item elem1 = this button/menu, and when mouse leave it set back to null.
so when form Activated we can call elem1.PerformClick() to click the button/menu item.
I have two buttons in a C# xaml project. The first button has the play functionality and the second one has the stop functionality.
How can I add the stop functionality inside the play button? Is this possible to add the functionality of one button inside another?
You need a ToggleButton for this purpose:
<ToggleButton Checked="ToggleButton_OnChecked" Unchecked="ToggleButton_OnUnchecked"></ToggleButton>
And:
private void ToggleButton_OnChecked(object sender, RoutedEventArgs e)
{
Play(); // Call Play method
}
private void ToggleButton_OnUnchecked(object sender, RoutedEventArgs e)
{
Stop(); // Call Stop method
}
Or:
<ToggleButton Click="ButtonBase_OnClick"></ToggleButton>
And:
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
if ((bool)(sender as ToggleButton).IsChecked)
{
Play(); // Call Play method
}
else
{
Stop(); // Call Stop method
}
}
The simplest way is to add both buttons on the same grid cell, with same layout properties.
Bind the "IsVisible" property of the button to the Boolean flag in your view model(like IsPlaying) using boolean to visibility converter. You will be knowing the state of playback in the view model. For the other button do the same with inverse boolean value.
Hope it helps.
In a Windows Phone app I have an TextBox and a Button. The user writes some text to the TextBox and taps the Button, the text from the TextBox is added to a list. The TextBox loses focus after the Button is tapped.
What I want to do is to set the focus back to the TextBox after the Button is tapped so the user can continue writing another text without needing to tap the TextBox.
I tried calling the Focus() method of the TextBox in the Button handler but this does not work. is there another, if any, way to do this?
When Button clicked try to add bollean flag = true. Then check this flag on event OnTextBoxLostFocus.
<TextBox x:Name="tb" Grid.Row="1" LostFocus="Tb_OnLostFocus"/>
<Button x:Name="btn" Click="Btn_OnClick" />
public partial class MainPage : PhoneApplicationPage
{
private bool flag;
public MainPage()
{
InitializeComponent();
}
private void Btn_OnClick(object sender, RoutedEventArgs e)
{
flag = true;
tb.Focus();
}
private void Tb_OnLostFocus(object sender, RoutedEventArgs e)
{
if (!flag) return;
tb.Focus();
flag = false;
}
}
Hope its help.
I have tried a lot of solutions, but this is the only one that works for me (Windows Phone 8.1 app).
First catch your TextBox's Loaded event, then call Focus(FocusState.Keyboard).
private void myTextBox_Loaded(object sender, RoutedEventArgs e)
{
myTextBox.Focus(FocusState.Keyboard);
}
Even I tried with lots of above solutions but none of them worked for me as am trying to focus on page load. Finally I got this solution and it worked.
private void txtBox_LayoutUpdated(object sender, EventArgs e)
{
txtBox.Focus();
}
What happens if you call:
yourTextBox.Select(0,0)
http://msdn.microsoft.com/en-us/library/system.windows.controls.textbox.select.aspx
you can accomplish this by programmatically giving it focus. This can be done by
calling its Focusmethod, although this call can fail (and return false) under certain conditions.
For example, you cannot set focus on a control from a page’s constructor; it’s too early. You can,
however, call it from a page’s Loadedevent.
The way that it worked best for me on the phone was, if I wanted to focus on a particular textbox when the page loaded:
private void OnPageLoaded(object sender, RoutedEventArgs e)
{
Dispatcher dispatcher = Deployment.Current.Dispatcher;
dispatcher.BeginInvoke(() => EnterLocationTextBox.Focus());
}
or if I just wanted it at a certain point. Just repeat these two lines:
Dispatcher dispatcher = Deployment.Current.Dispatcher;
dispatcher.BeginInvoke(() => EnterLocationTextBox.Focus());
I've searched on MSDN and here, but doen't seem to have an answer. Assume I have XAML code:
<button Name="button1" Click="ButtonHandler">
some other stuff
</button>
<button Name="button2" Click="ButtonHandler">
some other stuff
</button>
And in the CS code you have a simple handler:
private void ButtonHandler(object sender, RoutedEventArgs e)
{
}
I'm trying to figure out how to give each button, that are dynamically created by frame data, to have one handler and be able to uniquely identify themselves (name maybe?). And then use the Handler to be able to sort out the Unique identifier to perform an action for the Click event.
I'm not finding much, but that could mean I am missing the obvious....
The sender parameter to your ButtonHandler method would be the button that was clicked. From that you could get the name, or some other identifier. Is this not enough for your requirements?
Like this:
private void ButtonHandler(object sender, RoutedEventArgs e)
{
if (sender == button1)
{
//do stuff for btn 1
}
else
{
//do stuff for btn 2
}
}
//Edit:
And go from here
You can cast the object sender to a button and get all the properties of it.
Here is another question asking this:
Which button has raised onclick even?
I have a Windows Forms Link Label, "Refresh", that refreshes the display.
In another part of my code, part of a separate windows form, I have a dialog that changes the data loaded into the display in the first place. After executing this other code, pressing "Refresh" updates the data correctly.
Is there a simple way for the dialog menu to "click" the "refresh" Link Label after it has finished altering the data?
Using Visual Studio 2008.
For button is really simple, just use:
button.PerformClick()
Anyway, I'd prefer to do something like:
private void button_Click(object sender, EventArgs e)
{
DoRefresh();
}
public void DoRefresh()
{
// refreshing code
}
and call DoRefresh() instead of PerformClick()
EDIT (according to OP changes):
You can still use my second solution, that is far preferable:
private void linkLabel_Click(object sender, EventArgs e)
{
DoRefresh();
}
public void DoRefresh()
{
// refreshing code
}
And from outside the form, you can call DoRefresh() as it is marked public.
But, if you really need to programmatically generate a click, just look at Yuriy-Faktorovich's Answer
You could call the PerformClick method. But Generally it is better to have the Click event of the button call a Refresh method you write. And the menu call that method as well. Otherwise your menu depends on the button being there.
Edit:
A LinkLabel implements the IButtonControl explicitly. So you could use:
((IButtonControl)button).PerformClick();
you can use a method to refrech display, the bouton_click and the dialogBox call this method
public void refrechDate()
{
}
private void button_click(...)
{
refrechData();
}
private void MyMethod()
{
// ...
// calling refresh
this.button1_Click(this.button1, EventArgs.Empty);
// ...
}
private void button1_Click(object sender, EventArgs e)
{
// refresh code
}
