RadDropDownList and Tab issue

When the DropDownStyle is set to "DropDown" on the RadDropDownList, the control will not accept a <TAB> focus. The issue appears to be caused by the hosted textbox having its TabStop set to False. Is this a bug or by design?

This workaround appears to fix the issue. Thoughts?

RadDropDownList1.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown

Dim oTextbox As HostedTextBoxBase

oTextbox = Dropdownlist.DropDownListElement.EditableElement.TextBox.TextBoxItem.TextBoxControl

oTextbox.TabStop = True

Import Fonts

Is there any way to import fonts? Our designer wants us to use Open Sans font. It's not available in Visual Style Puilder or for any Winforms controls.

CellFormatting

Hi,

Apologies if this is a daft question, I usually get involved with web stuff.

We have a MatchLevelID Column in our RadGridView.
The MatchLevelID can either be 0, 1, 2 or 3
What we would like to do is set the background colour of the Cell depending on the MatchLevelID.
To do this, we are subscribing to the CellFormatting Event.
Here is the code we have so far :

private void rgv_CellFormatting(object sender, CellFormattingEventArgs e)
        {
            if (e.CellElement.ColumnInfo.Name == "MatchLevelID")
            {
                var cellInfo = e.CellElement.RowInfo.Cells[e.CellElement.ColumnIndex];

                var matchLevelID = (int) cellInfo.Value;

                switch (matchLevelID)
                {
                    case 0:
                        e.CellElement.BackColor = Color.Red;
                        break;
                    case 1:
                        e.CellElement.BackColor = Color.Orange;
                        break;
                    case 2:
                        e.CellElement.BackColor = Color.Yellow;
                        break;
                    case 3:
                        e.CellElement.BackColor = Color.Green;
                        break;
                }
            }
        }

What is happening is that the background colour is only being set in the MatchLevelID Cell for the Row that the Cursor is hovering over.
As soon as we move the Cursor to another Row the background colour for the new Row is changed and the colour for the old Row is lost.
Ideally we would like the colour to be set for all the Cells in the MatchLevelID Column when the Grid loads.

Any ideas ?

RadScheduler Description - NotifyCollectionChangedEventHandler

Now a keypress on "return/enter" in the field description in the dialog of editing appointment will fire the event NotifyCollectionChangedEventHandler.
Can I change this? A keypress on other keys don't fire this event - that's fine.

MultiSelectComboBoxColumn Filter

Hello,

i use the "Mutiselect drop down list column" from http://www.telerik.com/support/kb/winforms/gridview/details/mutiselect-drop-down-list-column-in-radgridview
I'm stuck in the implementation of a filter function (Filter must work in combine with other Columns). I found part of codes for custom filter functions and tried to combine them

The basic filter function works already:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using Telerik.WinControls.UI;

using Telerik.WinControls;

using Telerik.WinControls.Data;

using System.Diagnostics;

namespace _547099

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

DataTable t = new DataTable();

t.Columns.Add("ID", typeof(int));

t.Columns.Add("Name", typeof(string));

t.Rows.Add(1, "one");

t.Rows.Add(2, "two");

t.Rows.Add(3, "three");

t.Rows.Add(4, "four");

t.Rows.Add(5, "five");

t.Rows.Add(6, "six");

t.Rows.Add(7, "seven");

t.Rows.Add(8, "eight");

t.Rows.Add(9, "nine");

t.Rows.Add(10, "ten");

CustomColumn col = new CustomColumn("MutiSelect column");

col.Name = "Name";

col.DataSource = t;

col.DisplayMember = "Name";

col.ValueMember = "ID";

FilterDescriptor descriptor = new FilterDescriptor("Name", FilterOperator.Contains, 0);

//col.AllowFiltering = false;

radGridView1.Columns.Add(col);

GridViewTextBoxColumn col2 = new GridViewTextBoxColumn();

col2.Name = "Test";

radGridView1.Columns.Add(col2);

radGridView1.Rows.Add(new object[] { new int[] { 9, 6, 10 }, "ab"});

radGridView1.Rows.Add(new object[] { new int[] { 5, 1, 3 }, "abcd"});

radGridView1.Rows.Add(new object[] { new int[] { 8, 7, 1 }, "ef"});

radGridView1.Rows.Add(new object[] { new int[] { 4, 2, 1 }, "fgh" });

this.radGridView1.EnableFiltering = true;

this.radGridView1.ShowHeaderCellButtons = true;

this.radGridView1.EnableCustomFiltering = true;

this.radGridView1.CustomFiltering += new GridViewCustomFilteringEventHandler(radGridView1_CustomFiltering);

this.radGridView1.CellEndEdit += new GridViewCellEventHandler(radGridView1_CellEndEdit);

this.radGridView1.CellValidating += new CellValidatingEventHandler(radGridView1_CellValidating);

this.radGridView1.FilterExpressionChanged += radGridView1_FilterExpressionChanged;

}

void radGridView1_FilterExpressionChanged(object sender, FilterExpressionChangedEventArgs e)

{

Debug.WriteLine("Filter geändert: " + e.FilterExpression);

}

void radGridView1_CellValidating(object sender, CellValidatingEventArgs e)

{

if (radGridView1.ActiveEditor == null ||!( e.Row is GridViewFilteringRowInfo)) return;

if (e.Column.GetDefaultEditorType() == typeof(CustomDropDownListEditor))

{

filterValues.Clear();

foreach (CustomListDataItem item in ((CustomEditorElement)(((CustomDropDownListEditor)(this.radGridView1.ActiveEditor)).EditorElement)).Items)

{

if (item.Selected)

{

filterValues.Add((int)item.Value);

}

List<int> filterValues = new List<int>();

void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)

{

Debug.WriteLine("Refresh");

this.radGridView1.MasterTemplate.Refresh();

}

private void radGridView1_CustomFiltering(object sender, GridViewCustomFilteringEventArgs e)

{

if (filterValues.Count == 0)

{

Debug.WriteLine("FilterVal 0");

int fdi = radGridView1.FilterDescriptors.IndexOf("Name");

if (fdi != -1)

{

radGridView1.FilterDescriptors.RemoveAt(fdi);

}

if (radGridView1.FilterDescriptors.Count == 0)

{

return;

}

if (filterValues.Count > 0)

{

bool shouldVisible = false;

foreach (int cellValue in ((int[])e.Row.Cells["Name"].Value))

{

foreach (int j in filterValues)

{

if (cellValue == j)

{

shouldVisible = true;

break;

}

e.Visible = shouldVisible;

}

if (e.Visible) e.Handled = false;

}

So i can filter in custom column "Name" (MultiSelectDropdownColumn) and also in Column2 "Test" (TextboxColumn). good so far

After i filtered something in Column "Test" followed by clear this filter, i try to filter in custom column "Name" again but this time the filter don't work (all Rows will hidden or only one matching row will shown).

Does anyone have any idea where the fault lies?

LineSeries Y-Axis Innaccuracy

I'm trying to figure out why charting a LineSeries is so innaccurate. It seems like big spikes are causing some sort of pointy artifact that makes the max value seem higher than it really is.

Take for instance the first attachment, "Innaccurate1.png", where the data series is [0,0,0,0,0,0,0,0,0,0,1,0,0,0]

It appears to go over the y-axis grid line marking "1".

The second attachment, "Innaccurate2.png", shows how this effect is amplified as the chart control is shrunk. The spike now appears nearly over the gridline marking the value 2, though the same dataseries (with max value of 1) is still being charted.

This difference between the data max and the visual max isn't always <1 either. When charting a line series with a max value of ~1980, and a max Y-Axis value of 2000, the spike appears to go off the top of the chart. An error of more than 20 units!

Is there some way to solve this visual error to more accurately display my data?

context menu of Scheduler

On the Context Menu Showing Event of radScheduler,
I clear the current context menu then add some other RadMenuItems depending on the scenario.

on the first right click, the context menu shows.

but after right clicking anywhere on the RadScheduler (in any ActiveViewType)
the program crashes.

I got this error.

Global.cs:line 151 is Application.Run(Form mainForm)
succeeding details show that it is on the library.

I put a break point on the first line of ContextMenuShowing, but error occurs right before it reaches the breakpoint.

I am using Telerik Q1 2014 for WinForms.
Could you help me solve this? Or am I missing some restrictions on using context menu in RadScheduler?

Thanks!
