I would like to plot data on a scatter chart with 3 values, for example, x value (double type, frequency), y value (date/time, date and time) z value (double type, amplitude). z value having a color legend representing the value. Something like the attached intensity plot.
Thanks

Hello,
I have a couple questions related to RadGridView Self-Reference Hierarchy:
1. Is there a way to use the properties of System.Guid type as parent/child IDs? or only Int type?
2. How to configure a grid to be able to specify the columns manually and set AutoGenerateColumns property to false. I was not able to achieve it.
Thanks in advance!

Hi, I'm using a CheckedDropDownList fine, when the user press the Down Arrow key I show the dropdown ShowDropDown().
But I don't wanna it to be shown when the autocomplete is open, like when the user is switching between the suggestions pressing up and down arrows key...
public static bool IsAutoCompleteOpen(this RadDropDownList ddl) { return ddl.DropDownListElement.AutoCompleteSuggest != null && ddl.DropDownListElement.AutoCompleteSuggest.DropDownList != null && ddl.DropDownListElement.AutoCompleteSuggest.DropDownList.IsPopupOpen; }// the key down event{ if (e.KeyCode == Keys.Down && ddlItems.IsPopupVisible == false && ddlItems.IsAutoCompleteOpen() == false) { ddlItems.ShowDropDown(); e.Handled = true; }}
ddl.DropDownListElement.AutoCompleteSuggest is always null, so I can't find which is the correct property of AutoCompleteSuggest on CheckedDropDownList to check, any help?
Just noticed that when the grid as a sorting applied the following line ALWAYS return -1
var rowIndex = grdData.Rows.Add("whatever");
Without sorting it return the actual row. What i actually do is :
1 - Call the Grid.BeginUpdate();
2 - Clear the rows
3 - Loop in my collection and add 1 row per object
4 - Call the Grid.EndUpdate()


This is my code to select multiple rows and it works. But when i use the search bar the selected rows un-select themselves
//Enabling multiple row selection
dataGridViewCompanies.MultiSelect = true;
dataGridViewCompanies.SelectionMode = GridViewSelectionMode.FullRowSelect;
Any tips on how to keep the selected rows after i search so i can select as many as i want!
Thanks

Hi,
How do I remove/hide buttons specifically
from the backstage view of the Rich Text Editor Ribbon Bar.
With a regular backstage view I could do something along the lines of
this.radRibbonBarBackstageView1.Controls.Remove(this.radButton1);
but here I can't access the backstage view.
Thank you in advance

Hello.
I've been researching and made a code that could solve my problem of automatic visibility of the scroll bar in Telerik listView, Telerik ListControl and Windows listView
using System;namespace TelerikWinFormsApp2{ public partial class RadForm1 : Telerik.WinControls.UI.RadForm { public RadForm1() { InitializeComponent(); for (int i = 0; i < 50; i++) { radListView1.Items.Add("aa"); radListControl1.Items.Add("aa"); listView1.Items.Add("aa"); } //Windows listView Mouse Events listView1.MouseEnter += new EventHandler(listView1_MouseEnter); listView1.MouseLeave += new EventHandler(listView1_MouseLeave); //Telerik listView Mouse Events radListView1.MouseEnter += new EventHandler(radListView1_MouseEnter); radListView1.MouseLeave += new EventHandler(radListView1_MouseLeave); //Telerik listControl Mouse Events radListControl1.MouseEnter += new EventHandler(radListControl1_MouseEnter);

I hope it helps.
