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.

I am using c# drag and drop panels .the panels keep appearing and disappearing.Also i need help with panel box functionality words like "bring to front and bring to back" i think this is what is messing my panels up.What do they mean?
The Windows Forms Designer has a concept called Z-order. When two controls overlap, the Z-order determines which control will show up on top.
For example, suppose you have two controls called textBox1 and pictureBox1 on a Windows Form. Programatically, this refers to the Windows Form itself, Controls is the default list of controls in that Form, and textBox1 and is the actual control we are changing.
Selecting the menu option Bring to Front is equivalent to calling the control's BringToFront() method. This moves the control to the beginning of the default Controls collection of the Windows Form. So if you call Bring To Front on textBox1, it will show up above all other controls on your Form. Programatically,
// Bring the control in front of all other controls
this.textBox1.BringToFront();
Selecting the menu option Send to Back is equivalent to calling the control's SendToBack() method. This moves the control to the end of the default Controls collection of the Windows Form. So if you call Send To Back on textBox1, it will show up behind all other controls on your Form. Programatically,
// Send the control behind all other controls
this.textBox1.SendToBack();
You can also have finer control over the ordering programmatically. There is no way to do this in the UI. So:
// Put the control at the 2nd index in the Controls collection of this Form
this.Controls.SetChildIndex(this.textBox1, 2);
This page Layering Objects on Windows Forms gives some more details.
The page Windows Forms Controls: Z-order and Copying Collections has examples on how to control Z-order programmatically.
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 have a dropdown which consists of all the controls names like textbox , label , combobox , dropdown list...etc.
if in the starting one label control is placed on form,on user selection of control name in dropdown list ,that label control should be replaced with the user selected control dynamically...like this,what ever control user wants to keep can keep just by selecting dropdow
i need the controls to be dynamic.that is only the requirement.whenever a person ,say admin want to change the controls from CMS,he can easily change with the selection.
You'll need to use some Javascript magic for this. Whats the specific requirement?

How can i create a window that holds Patient data in it? The 2 records that you see is in List View. I would then using ContextMenuStrip for text "View Details". When View Details is clicked i need to show the context. For web development this could be done via Javascript,div and panels. How that should be WinForms?
Please Help.
Thanks!
How about:
Make a form, formMaster, that displays the Schedule records in GridView
Upon double click on a row event, display another form, formDetail, passing on the selected patient id
Upon loading of the formDetail, get the patient record based upon that ID and set the controls accordingly.

You can use the GroupBox, or the Panel control itself. Usually, with WinForms GroupBox is more of a common use.

I take it you mean as a popup panel, like you would see using javascript such as overlib (http://www.bosrup.com/web/overlib/) - implementing this behaviour in winforms.
The way I have done this in the past is by having a user control which is an extended panel, and on the mouseenter event of the specific control I have shown the panel at the mouses's x,y coordinates, which are accessible from the event arguments in the handler.
Then on mouseleave you hide the usercontrol.
I have a custom control based on the label control. My question is how I disable the selection box around this custom control when a user selects it while in design mode.
I would like to just change the font color when selected, and then change it back when unselected.
The reason for this is because when you have many labels with small font very close together it makes it hard to see the other labels when you select one of them and the selection box from the one selected obscures the user from seen the other labels that are very close to the one selected.
You cannot prevent it from being selectable at design time. It is considered a component of the form and you will always be able to select it in order to be able to delete it or modify its properties by selecting it.
