Remarks

Enable the AllowContentSelection property to allow users to select text displayed by HTML templates. Note that as users drag the mouse pointer to select a portion of text, button captions, images, and other HTML elements along the way are also selected.

Text Selection in Data Grid Items View

Note

Currently, users can select only one row at a time. Selection across multiple rows is not currently available.

The textual content of the selected region is stored in the SelectedText property. The code below copies this property’s value to the clipboard when a user presses Ctrl+C:

private void OnKeyDown(object sender, KeyEventArgs e) {
    ItemsView iView = sender as ItemsView;
    if (e.Control && e.KeyCode == Keys.C)
        Clipboard.SetText(iView.SelectedText);
}

When the selection changes, the SelectedTextChanged event occurs. Handle this event to inspect and modify the SelectedText property value. For instance, you can cleanse it from the contents of non-textual elements that were selected along with regular text.

private void OnSelectedTextChanged(object sender, EventArgs e) {
    ItemsView iView = sender as ItemsView;
    string updatedText = iView.SelectedText.Replace(" OK Cancel ", " ");
}

You can also use the user-select CSS property to prevent unwanted HTML elements from being selected when the AllowContentSelection property is enabled.

<div class="button unselectable">Cancel</div>
.unselectable { user-select: none; }

If the AllowContentSelection property is set to DefaultBoolean.Default or DefaultBoolean.False, utilize the user-select CSS property to enable selection for individual elements.

.selectable { user-select: all; }
.selectableText { user-select: text; }
