In simple mode, binding works correctly.

..............

//Define property

private float start;
public float Start
{
get => start;
set
{
if (value == Start) return;
start = value;
OnPropertyChanget("Start");
}
}

..............................................

//Binding

radTrackBar1.DataBindings.Add("Value", Data, "Start", true, DataSourceUpdateMode.OnPropertyChanged);
radTrackBar2.DataBindings.Add("Value", Data, "Start", true, DataSourceUpdateMode.OnPropertyChanged);

.........................................................

How can I use binding in range mod?

radTrackBar1.Ranges[0].Start = 1;
radTrackBar1.Ranges[0].End = 50;
radTrackBar2.Ranges[0].Start = 1;
radTrackBar2.Ranges[0].End = 50;

//Define property ??????????????????????

//Binding ??????????????????????????

Thanks!

Background Color spreads to other cells when scrolling

I've looked at other posts, but I didn't see where I went wrong.

(review attached screenshot for a better understanding)

In my situation, I add background color to row cells where this is an "A" value in the cell. This stands for an aisle in a warehouse.

If you scroll slowly, then the background color stays within the rows with an "A", but if you scroll too fast, the display shows green in various cells. Also, if I clear the grid and rebuild it with new data, the background color is not reset. The previous rows that were green are still green.

What am I missing?

01.Private Sub dgvMain_CellFormatting(sender As Object, e As CellFormattingEventArgs) Handles dgvMain.CellFormatting

02. If _LeftOrRightConveyor = "LEFT" And e.CellElement.ColumnIndex = AisleColumnLeft_Idx Then

03. e.CellElement.BackColor = System.Drawing.Color.LightGreen

04. ElseIf _LeftOrRightConveyor = "RIGHT" And e.CellElement.ColumnIndex = AisleColumnRight_Idx Then

05. e.CellElement.BackColor = System.Drawing.Color.LightGreen

06. End If

07.

08. If e.CellElement.Value = "A" Then

09. e.CellElement.BackColor = System.Drawing.Color.Lime

10. End If

11.End Sub

Theme not being applied to show dialog

Hi For some reason the theme fluent dark is not being applied to a show dialog function. I have included the designer file and the main form code below for your to check but all other forms are working fine which is weird.

Main Form Code.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using Telerik.WinControls;

using FuelActivityTrackerDapperDal;

using FuelActivityTrackerDapperDal.Models;

using FuelActivityTrackerDesktop.Forms;

using System.Linq;

namespace FuelActivityTrackerDesktop.Forms

{

public partial class Login : Telerik.WinControls.UI.RadForm

{

ActivityTrackerDapperDal db = new ActivityTrackerDapperDal();

public IEnumerable<Users> _users { get; set; }

public Login()

{

InitializeComponent();

}

private void Login_Load(object sender, EventArgs e)

{

_users = db.GetALLUsers();

ThemeResolutionService.ApplyThemeToControlTree(this, "FluentDark");

}

private void btnLogin_Click(object sender, EventArgs e)

{

if(txtUsername.Text == "")

{

MessageBox.Show("Please enter your login details", "Fuel");

}

Users _user = _users.Where(w => w.UserName.ToLower() == txtUsername.Text.Trim().ToLower() && w.Password.ToLower() == txtPassword.Text.Trim().ToLower()).FirstOrDefault();

LoggedIn.UserName = _user.UserName;

LoggedIn.UserId = _user.id;

LoggedIn.StaffId = _user.StaffId;

if (_user.isActive == true)

{

frmMain _frmmain = new frmMain();

this.Hide();

_frmmain.ShowDialog();

}

else

MessageBox.Show("Your account has been made inactive , Please check with Administrator", "Fuel");

DialogResult = DialogResult.OK;

}

private void txtPassword_KeyDown(object sender, KeyEventArgs e)

{

if (e.KeyCode == Keys.Enter)

btnLogin_Click(sender, e);

}

Show "Click Here to Add a New Item"

Hi

I have a grid bound to an empty dataset. When I load the form, it shows an empty row in the grid instead of showing the "Click Here to Add a New Item". As soon as I've added a row, the "Click Here to Add a New Item" row appears. How can I get it to show "Click Here to Add a New Item" at the start instead of showing an empty row?

Filter popup after localization

Hi guys,

quick and simple: after localization to german, from "Cancel" -> "Abbrechen" the cancel button is cut off, due to the longer text.

See the attached image. How can I fix it?

Note: Making popup wider did not help. How do I access the cancel button to adjust it?

thx and best regards,

Darko
