Hi,
I have a TextBox and I need to open a context menu (that I build dynamically based on the text present in the control) near at the current position of the caret.
How can I get the coordinates of the caret so I can pass them to the menu show method ?
I can change the control to a RadTextControl if needed.

Hi,
I've implemented a DataEntry and everything works fine.
What I'm trying to do is to add a button near a TextBox which clicked should open up a new window with advanced search for selecting a new value to put in the TextBox.
Is this possible?
I'm trying to insert a custom control which contains a TextBox and a Button, but i don't know if it's the right way.
Thanks.

I am using the EnableHeaderCheckBox to have a "Select All" checkbox in the header of my boolean column. I have the radgridview.EnableSorting = true and they work just fine, but when I click the "Select All" header checkbox and then try to sort any column, they do not sort at all. It does nothing. I am using Telerik UI for Winforms version 2017.2.502. Can someone please help?

I use the font property when working with RadPropertyGrid.
My user entered a font size of -1. An exception is thrown and the program falls.
For comparison in the PropertyGrid (WinForms), this situation is correctly handled.

I think I read how to do this but searching 'FormClosing' in this forum didn't find anything much.
I simply need to cancel the closing of a form (after user dialog confirmation). Is this the correct approach?
private void OnFormClosing(object sender, FormClosingEventArgs e){ var dlg = new DlgConfirmUnsavedForm(); var result = dlg.ShowDialog(); if (result == DialogResult.Cancel) { e.Cancel = true; OnClosing(e); return; //?? } else if (result == DialogResult.Yes) { SaveForm(); } ...}
By the way, post editing is terrible!

Hi,
I've a problem (again) when the MCCB is used in an Excel addin environment.
If the MCCB is used on a normal form (non modal) and you scroll (mouse wheel) inside the dropdown (grid) then the complete addin hangs.
If you do the same in an modal form, everything works fine.
Sample project is attached (rename to zip)
Steps to reproduce:
button2 -> opens modal form (OK)
button1 -> opens non modal form (not OK)
open dropdown and then scroll inside grid with mouse wheel
Is there any workaround? (even if I have to disable mouse scrolling, would be better than an hanging application)

I'm using two RadTreeView to Drag and Drop Nodes from Right to Left. When "Node 1" is Drag from Right and Drop to Left RadTreeView a Dialog is shown.
If I Drag and Drop other Node before "Node 1" the Dialog stuck and I cannot write on the TexBoxes.
How can I solve this issue?
Main Form
https://i.stack.imgur.com/Qf1QM.png
public partial class Main : RadForm{ public Main() { InitializeComponent(); } private void RightRadTreeView_DragEnded(object sender, RadTreeViewDragEventArgs e) { if (e.Node.Text == "Node 1") { new RadForm1().ShowDialog(); } } private void Form1_Load(object sender, EventArgs e) { //Right this.RightRadTreeView.Nodes.Add(new RadTreeNode { Text = "Node 1" }); this.RightRadTreeView.Nodes.Add(new RadTreeNode { Text = "Node 2" }); this.RightRadTreeView.Nodes.Add(new RadTreeNode { Text = "Node 3" }); this.RightRadTreeView.Nodes.Add(new RadTreeNode { Text = "Node 4" }); }}
Dialog Form
