I am having this situation: when click on the scroll bar to up or down the RadListView the SelectedItemChanged event is raised. I have a work around in my client code to prevent it but it's ugly... somebody deal with it.

Steps to reproduce:

1) Have a RadListView in your form with many data to it shows the scroll bar 

2) Subscribe your for to the SelectedItemChanged event 

..
list.SelectedItemChanged += ListCheckedItemChanged;
..
protected void ListCheckedItemChanged(object sender, EventArgs e)
{
...
}

3) Run your form and select an item before use the scroll bar

4) click in the button to Up/Down the scroll bar. The subscribed is called (use some break point to check it)

When the user selects rows on the grid, tis very hard to figure out which ones are selected or not.

Is there a way at design time I can play with the color to be used for this?

 

Thanks

Hello,

When setting the property this.IsMdiContainer = true;
the main form changes color, how can I change the color?

       private void MenuPrincipal_Load (object sender, EventArgs e)
         {
            this.IsMdiContainer = true;
            this.radDock1.AutoDetectMdiChildren = true;
         }
        private void radButton1_Click (object sender, EventArgs e)
         {
             radForm1 form = new radForm1 ();
             form.Text = "Test Form" + DateTime.Now.ToShortTimeString ();
             form.MdiParent = this;
             form.Show ();

         }

Here I show the photo

Thank you.

I have a radRibbonBatGroup.

I would like to put the following into it;

Label: Textbox    Label: DropDownList1  Label: DropDownList3

Label: Textbox    Label: DropDownList2

How do I do that?

Each time I add a element in the VS UI it goes next to each other.

Also don't see a label object to add for each item.

Thanks

Deasun.

Hi all

I'm working with Visual Studio 2017, .NET 4.6.1, Telerik UI for WinForms 2018.2.621

This is the code:

 

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using Telerik.WinControls.UI;

namespace TelerikTest
{
    public partial class Form1 : Form
    {
        private List<string> list = new List<string>() { "one", "two", "three" };
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            radCheckedDropDownList1.Items.Clear();

            foreach (string item in list)
            {
                radCheckedDropDownList1.Items.Add(new RadCheckedListDataItem(item, false));
            }
        }
    }
}

If I fill the radCheckedDropDownList after having selected an item by click (SelectByClick.png) all is fine.

If I fill the radCheckedDropDownList after having selected an item using autocomplete (SelectByAutoComplete.png), I get a NullReferenceException (NullReferenceException.png).

 

Could someone please tell me, what I'm doing wrong?

 

Thanks in advance

Daniel

Hi

 

I'm building a chart but I wont to specify the vertical and horizontal axis minimum and maximum value.

also I want the vertical axis ti be inverse and to cross with the horizontal axis at the bottom (vertical axis maximum value)... but the code I wrote is not doing anything of what I want. this is what I code:

            radChartKatzA.Series.Clear();
            LinearAxis katzA_hor_Axis = radChartKatzA.Axes.Get<LinearAxis>(0);
            LinearAxis katzA_ver_Axis = radChartKatzA.Axes.Get<LinearAxis>(1);
            katzA_hor_Axis.Minimum = 0;
            katzA_hor_Axis.Maximum = 800;
            katzA_hor_Axis.MajorStep = 100;
            katzA_ver_Axis.Minimum = 0;
            katzA_ver_Axis.Maximum = 1400;
            katzA_ver_Axis.MajorStep = 50;

            katzA_hor_Axis.IsInverse = true;

            katzA_hor_Axis.LineWidth = 6;
            katzA_hor_Axis.TickWidth = 8;

            ScatterLineSeries katzLinea1A = new ScatterLineSeries();

            katzLinea1A.DataPoints.Add(0, 700);
            katzLinea1A.DataPoints.Add(350, 700);

           radChartKatzB.Series.Add(katzLinea1A);

 

thank you for your help

Might have missed this somewhere, but is there a way the user can same count the rows  or say summarize this column?

Kind of like they do for the filters but for counting and totals of a column?

 

Thanks
