I have a C# webforms page where I want to drag html elements into a telerik radeditor. This part is working as expected except that when you drag an element onto the editor I want the cursor position in the radeditor to follow the mouse. It is set up similar to this demo on Teleriks web site. Except I am using a listview instead of treeview. http://demos.telerik.com/aspnet-ajax/editor/examples/treeviewandeditor/defaultcs.aspx
I have tried simulating clicks on the radeditor to move the cursor, but no luck there. Any ideas?
Edit:
I have made a semi-working solution last week. Its far from perfect but I decided to share it in case some one else wants to make it better.
function controlDragging(sender, args) {
var event = args.get_domEvent();
var editor = $find("radEditLayout");
if (isMouseOverEditor(editor, event)) {
var x = event.pageX - event.offsetX;
var y = event.pageY - event.offsetY;
var node = editor.get_document().elementFromPoint(x, y);
if (node) {
setCaret(editor, node, 0);
}
}
}
function setCaret(editor, element, position) {
var selection = editor.getSelection(),
range = selection.getRange(true);
if (range.setStartAfter) {//W3 range
range.setStartAfter(element);
}
else { //IE7/8 textRange
range.moveToElementText(element);
range.moveStart('character', position);
}
range.collapse(true);
selection.selectRange(range);
}
function isMouseOverEditor(editor, event) {
return $telerik.isMouseOverElementEx(editor.get_contentAreaElement(), event);
}
Any more suggestions??
Perhaps you will be able to figure out something with ranges, but I am not sure exactly how as I have not used them. Here are the basics on getting an already selected range http://www.telerik.com/help/aspnet-ajax/editor-getselection-1.html and here is how to get the document object so you can use ranges in it: http://www.telerik.com/help/aspnet-ajax/editor-getting-reference-to-radeditor-documentobject.html. Perhaps this can help you get started but I think it will be a lot of work: How to set caret(cursor) position in contenteditable element (div)? because I am not sure how you can calculate the position at which you want the cursor from the mouse coordinates.
