In ListView there are 3 option of SelectionMode
1.Single - only one item can be selected.
2.Multiple - you can select muliple items, one after the other.
3.Extended - You can select multiple items and used Ctrl or Shift key.
I'm need to select some items in ListView as text in TextBox.
i.e. press with the left button of mouse, until the mouse is up.
and mark all between items as Selected.
How can I make it?
Thanks
1.Single: SelectionMode="Single"?
2 Mutiple : i think use binding

3

Or You try this line SelectionMode="Muti..."
Firstly, the porpose of this problem is to display listView of TextBlocks for allow use ItemsSource of ListView for display text for several reasone.
behind each textBlock that contains a word, there are in the ViewModel class named Word. that contains the text of the word and property of IsSelected.
I solve this problem, by adding 3 EventSetter event to the ListViewItem,
1.PreviewMouseLeftDown
2.MouseEnter
3.PreviewMouseLeftUp
and adding a flag of IsInSelection, and two object Word that present the control in the view,1.firstSelectionWord, 2.lastSelectionWord.
and, when the first event raise, i update the current control to be Selected.
and set a flag IsInSelection to true. and set firstSelectionWord = lastSelectionWord = current word pressed.
in the MouseEnter event i checked if IsInSelection is true, and them mark also the current control to Selected=true. set the lastSelectionWord = current word pressed.
and call a method that mark all the Word between them as selected.
in the PreviewMouseLeftUp function, i set the IsInSelection = false.

I need to get results(price) into a label selecting by radiobuttion and checkbox and in the end need to add them up. I need to get all the results in a label.
need to get result in label(cost excl. VAT)
list of radiobutton and checkboxes
To build on what Matt Stannett said, The Calculate method would actually be the Changed event handler for all the Checkboxes and Radiobuttons. Basically, anytime anything is changed, recalculate the value and display it of the label.
I would suggest looking into the CheckBox.CheckedChanged and RadioButton.CheckChanged events then have some sort of Calculate method that sets the Text property of the label.
I have a Combobox with several items (C# Labels because I want to change individual text colors). Within callbacks, when editing some textboxes, I change the color and/or text of the items. When I click on the combobox I see that the items in the list have the correct color/text. However, the color/text changes of the selected item are not directly reflected in the shown combobox text. How can I achieve that?
I tried to set the Text property of the combobox itself: no effect. Also setting the selected item to an empty Label and then set it back to the correct Label has no effect. If I set SelectedIndex to -1 and then back to the correct selected index it works and the shown text is updated, but this triggers the SelectionChanged callback which I do not want. I could first detach the SelectionChanged callback from the combobox and then attach it again, but this is in my opinion very ugly programming.
Maybe I am missing something simple...
Edit
I tried binding, following the suggestion of SLak:
List<Label> labels;
MyComboBox.ItemsSource = labels;
The result is still the same. Suppose index 0 is selected. When I change the corresponding Label:
labels[0].Contents = "new content";
then it is not reflected in the selected text of the combobox. When I click the combobox I can see the new text in the unfolded list, but only when I change the selection and then go back to index 0 the new text is shown by the combobox as the selected item. That synchronization should be autmatically.
I am displaying items in a listview, and want them to be selectable by clicking anywhere within the row.
In task manager, clicking within a row selects the entire row. This is true regardless of which column you click in, and whether or not you click text or blank area.
In a newly made listview, a different behavior is observed:
It can only be selected by the text in the first column only. The index cannot be selected from any other column, and cannot be selected by blank space in the first column.
How can I replicate the behavior of task manager, where click (and hover, etc) events are triggered anywhere within the row?
As TaW said, FullRowSelect. Either change in properties or put listView.FullRowSelect = true; somewhere in your code.

Have you tried to set/ correct the Control.TabIndex properties of the freshly added item?
See MSDN - Control.TabIndex Property .
Maybe you like to do this using the AddingNewItem event in order to manipulate added items before they are displayed.
See MSDN - DataGrid.AddingNewItem Event.
Hello I have a datagridview with many rows. I would like to be able to click on a cell and type some letters and have a matching row get selected (or scroll to it). I can sort out which column it is sorting to, but right now there is no 'search' capability.
When you open a Window's Explorer window and click on a file, you can start typing to have the selection move to the file/folder that matches your keystrokes.
Is this possible with the datagridview?
What I meant was the DataGridRow.IsSelected property. Since you said you know which rows contains your results, you can call DataGridView.ClearSelection() and then set the IsSelected property of the row that contains the data to true.
