This is the first time I'm trying to build something with a tab control.
At first I made a small application in .NET 4 C#, which had a listbox as a stand alone at its main window and now I want to add a tab control and move the listbox into one of the tabs and a listview into the other tab so I can also present Icons.
My problems I'm facing are as follows:
1) I'm now adding the listbox dynamically to the tab control like this:
private ListBox listBoxMember = new ListBox();
public Form1()
{
listBoxMember.Size = tab1.Size;
tab1.Controls.Add(listBoxMember);
}
When starting the application, it seems like the listbox doesn't fit itself inside the entire tab and I can see it's borders inside the tab.. How can I fir the listbox completely into the tab so it would seem to the user that the tab itself is like a listbox?
2) Before my change I made a context menu which was activated with the listbox's mouse down event upon right clicking the mouse. Now after adding the listbox inside the tab, the menu won't open when the mouse is clicked. How can I use the context menu I made and use it the same way as I did when the listbox was a stand alone control?
To fill the tab with your ListBox, use the Fill property.
listBoxMember.Dock = DockStyle.Fill;
Also since you are now creating the ListBox dynamically you'll need to set the ContextMenu dynamically as well.
listBoxMember.ContextMenu = myContextMenu;
Also be sure to give the listBoxMember a name so you can find it in the tab1.Controls collection.
listBoxMember.Name = "listBoxMember";
tab1.Controls["listBoxMember"];

In windows form application, i created a usercontrol page. Here, I need to add a myowncontrol from tool box.
I just added myowncontrol in the tool box. by the way of browsing dll and placed it in tool box.
Here, when i drag and drop any one of default control, which can easily dragged and placed in the usercontrol page. But when i try to drag and drop myowncontrol into usercontrol page , its not working.
Can't able to drag and drop.
(i mean i can pick the control from the tool box but i can't able to place it where i want)
what is the problem in my area?
I'll admit that this does not directly answer your question, but I am wondering if you have tried to programmatically add the control to a Form? You would need to add a reference to the DLL that contains the UserControl and then do something similar to below in your source code.
var myCtrl = new MyControl(); //your UserControl class here
myCtrl.Location = new Point(25,25); //give it a location
this.Controls.Add(myCtrl); //add it
Also another thought... Are you sure that it's not really being added and it's just not visible? For a Form or UserControl in the Visual Studio Properties Window there is a drop-down at the top which contains all the controls that have been added.
I have a UserControl with some buttons in it (btnNew, btnCancel, btnEdit).
I used this UserControl in another project. When I press the tab key in this project, the selection button doesn't change regular!
For example, I want that if the user presses the Tab key, first the btnNew button is selected, then the btnEdit button, and finally the btnCancel button.
But in this project, when pressing the Tab key, the btnCancel button is selected first.
I want to manage the tab order of the buttons myself, and not use the default. How can I do this?
Thanks...
To set the order of how the buttons will be selected on tab press use the property
TabIndex
it defines the order the tabs will be selected. So set the tab index like the following
btnNew.TabIndex = 0;//selected first
btnCancel.TabIndex = 1;//the second
btnEdit.TabIndex = 2;//the last one
When the form designer is open go to View > Tab Order this will allow you to set the tab order in a very simple and easy way.

I don't have much knowledge on Windows Forms, As I know there will be a TabIndex property for each control.
You can set your order using that.
Menu View-> TabOrder
or
manually set TabIndex for each control.
To set the tab order of a control
On the View menu, click Tab Order. This activates the tab-order selection mode on the form. A number (representing the TabIndex
property) appears in the upper-left corner of each control.
Click the controls sequentially to establish the tab order you want.
When you have finished, click Tab Order on the View menu again to leave tab order mode.
Quoted from here.
You could also change the TabIndex property of each of the controls individually in the Properties pane. Or change it programatically like so btnNew.TabIndex = 0;.
I have a ListPicker (from Telerik's Rad Controls suite) in PopUp Mode (with around 200 elements) with its visibility set to Collapsed. I want to open when it when I press a button, instead of when I press the control itself.
Basically I'm asking if there's any way of programatically opening a UI element in Windows Phone (something like Control.Open() in the code behind).
The context for my question is the following:
as you know, the selected item of a list picker is displayed in the page containing the control.
users can click on this item to activate the control.
I want to display only one of the properties in the page containing the control (for example MyObject.Name instead of the entire MyObject), but I can't do this because the SelectedItem and ItemsSource need to be of the same type.
I'm thinking of styling a button to look identical to the ListPicker's selected item.
I need to open the ListPicker programatically when I click on the button, I'll bind the button's text to MyObject.Name
Alternatively, I could just do a data template for the way the list picker is displayed, but I'm not convinced it's possible.
Found the answer. It seems Telerik's List Picker allows you to set both an ItemTemplate for displaying items in the actual page, and a PopupItemTemplate for displaying items when the list is expanded. Both are Data Templates, so you can use Binding for values.
I am creating a Windows forms user control. This control has a textbox and a listbox.
When the end user types text in the textbox, the listbox will appear and filter the data
depending on the text box. The data is set by a datasource.
I have created this control because I want to filter in the contains of data "not start with."
Now after I create the control I found a problem when the list appear it did not appear out of form boundaries.
I change the control size in appear and disappear the listbox. What can I do?
You can not show a ListBox out of the boundaries of its parent Form. What you really wan to do is open a new Form where ListBox is visible.
Hope this helps.
In XAML, is it possible to display a new "screen" when a button has been clicked?
Like for example, in Android apps, you click an option from the main menu and normally a new screen is displayed with different options.
I would like to to do this, I don't want new windows appearing, context menus is not quite what I want either.
Yes. Use TabControl populated with TabItems to switch "frames". You can add as many tabs as you like at design-time.
Then at run-time just change SelectedItem or SelectedIndex property of the tab control to redirect your user to the right tab.
