There are Windows Form with some text controls and button. User with TAB and Enter can focus next element. Button should be skipped.
How can I omit Windows Forms Control (OpennetCF Button2) from the tabbing order?
You just set its TabStop property to false
button1.TabStop = false;

I have a listbox which uses the datatemplate to generate a list of checkboxes. The issue is when using the keyboard , the focus moves twice over the item. Once because of the list item and next for the checkbox. In order to change this in my code-behind, I set the checkbox IsChecked to True when Space is pressed for the list item. The issue is , the narrator reads the 'Space' instead of mentioning the 'checked' or 'unchecked' status of the checkbox. I understand this is because the foucs is on the list control and not the checkbox control. Is there a way for the narrator to read 'checked' without having the focus?
I want to set focus on a button while caret is present in textbox and user can still enter data to textbox. But when user presses enter key, button press will be simulated.
I am currently using a work around to solve this problem by handling onKeyDown event and checking for enter key. But problem is there is no clue for user to understand this as there is not blue border around the button that indicates focus on button.
Here is a example of what I want to implement (user can enter text in textbox while focus is on :
I have tried to search on google and StackOverflow but could not find any relevant result.
This is a fundamental Windows principle. It's not possible to have 2 controls (windows) focused at the same time.
So the focus should be inside the text box. But you can get the visual indication needed by setting the ok button as AcceptButton of the form (you might also want to set cancel button as CancelButton).
In the form constructor, load event or using designer:
this.AcceptButton = okButton;
There is no need to handle KeyDown event - as soon as the text box is not multiline, pressing Enter while the focus is inside it will generate ok button click. The same applies for the button set as CancelButton when you press ESC.
In windows form, I have 5-7 combobox on one 3 tab pages of tab control.
This tab control reside in a group box.
There are other two groupboxes containg other text box and listview controls.
Problem is, When defualt load the form control then focus set on combobox and unable to unselect.
Tried by changing property- causevalidation to false but no output.
Please guide.
Add a line on Page Load to set focus on the control you want to focus.
For Ex:
txtName.Focus();
EDIT
Use this
ActiveControl = yourcontrolNameToWhichYouWantToSetFocus;
You can set the TabIndex of the controls, the lowest index will be the first focused. (TabStop should be true)
I you want to set focus to another combobox you should call Select() method.
I have a C# .NET WinForm. In the form, I allow a user to add an item to a ListView by double-clicking in the ListView. This adds a TextBox control to the ListView and places the key cursor in the TextBox so a user can type.
I detect that a user is done with an item in a couple of ways (e.g. pressing Enter, Esc, Tab...), but also when they Leave (TextBox.Leave) the TextBox.
The problem is this set of steps:
User triggers TextBox.Leave by mousing down outside of the TextBox.
I add the new item to the ListView.
I select the the new item in the ListView.
Mouse up occurs and the new item that I just selected, loses focus and is unselected.
What I would like is for TextBox.Leave to be triggered by MouseUp, not MouseDown. How can I accomplish this?
Edit: Cody suggests using the ListView.LabelEdit property. Here are my results trying that:
listView_DoubleClick(...) {
listView.LabelEdit = true;
if(double clicked on existing listViewItem) {
listViewItem.BeginEdit(); //this works as expected
} else {
var newItem = listView.Items.Add("");
newItem.BeginEdit(); //this doesn't work, see below
}
}
The call to newItem.BeginEdit() only works when the user double clicks where the new item will show up. If they double click on any other blank area in the listview the new item is added, but it does not enter edit mode. What's going on here?
Pressing the mouse down on another control is causing that other control to request the focus and so the focus moving causes the TextBox.Leave event to occur. Preventing ever other possible control from requesting the focus is not a very viable option. But luckly you only need to prevent the ListView from using the MouseDown to shift focus. So you need to override the WndProc of your ListView and when the MouseDown windows message occurs and you are currently showing a TextBox you eat the message. In order words you do not allow the base class to process it.
When setting up a Winform with textbox controls, and going to View Tab Order -
how do you indicate when you are done setting tab order and want it to be saved?
Is there any other way to set the Tab Order of the controls on the form?
When you are finished, click the tab order again or press Esc.
You can set the tab order using the Tab Index property either in design mode or at runtime.
To indicate that you are done, hit ESC.
You can change the tab order by setting the TabIndex property on the controls themselves
When you begin setting the tab order you klick the tab order button. When you are done you click it again to disable it.
You can set the tab order number in each controls properties sheet or at runtime via the TabIndex value.
