Font Size

Hello When I change the font of a radmaskededitbox, the font family changes correctly, but the size seems to be wrong.

here is how I change the font:

                            Dim meb As RadMaskedEditBox = TryCast(ctrl, RadMaskedEditBox)
                            meb.Font = NewFont
                            meb.Controls(0).Font = NewFont
                            meb.MaskedEditBoxElement.Font = NewFont

Atteched a screen copy where all controls fonts are set to "Comic Sans MS;9pt" and the radeditmaskedboxes show larger fonts

Any suggestion ...

thanks in advance

[Solved] RadRangeSelector issues with axis labels and range of values

Hello Telerik Support Team,

I have 2 issues with the RadRangeSelector:

1. The Scale doesn't use the format settings of the chart. The category member datatype of the barseries is DateTime and I use this code to set the format:

BarSeries.HorizontalAxis.LabelFormat = "{0:dd.MM}";

In the first screenshot you can see that the rangeselector shows the full DateTime format with hours, minutes and seconds.

2. The RangeSelector doesn't respect the minimum and maximum values of the chart. I use this code to set then:

LinearAxis verticalAxis = cvChart.Axes.Get<LinearAxis>(1);

if (verticalAxis != null)

{

verticalAxis.Minimum = 0;

verticalAxis.Maximum = 100;

//verticalAxis.MajorStep = 100;

}

On the second screenshot i marked the behaviour, if the ValueMember for all items in the datasource is 0.

Are there possibilities for the RangeSelector to set the formatting options and the minimum and maximum values?

Regards,

Stephan

[Solved] SetColumnWidth

I've been playing with the 2020 R1 demo and am having trouble setting and getting column widths of the VirtualGrid.

To set the column widths I've tried both TableElement, as in the documentation, and MasterViewInfo, which I found in the forums.

A little insight would be great!

Thanks!

using System;

using System.Collections.Generic;

using Telerik.WinControls.UI;

namespace TelerikWinFormsApp1

{

public partial class RadForm1 : Telerik.WinControls.UI.RadForm

{

List<Foo> data = new List<Foo>();

public RadForm1()

{

InitializeComponent();

this.Text = "Foo";

radVirtualGrid1.AutoSize = false;

this.radVirtualGrid1.CellValueNeeded += new Telerik.WinControls.UI.VirtualGridCellValueNeededEventHandler(this.radVirtualGrid1_CellValueNeeded);

this.radVirtualGrid1.ColumnWidthChanged += new Telerik.WinControls.UI.VirtualGridColumnEventHandler(this.radVirtualGrid1_ColumnWidthChanged);

//These methods do not set the column width

radVirtualGrid1.MasterViewInfo.SetColumnWidth(0, 300);

radVirtualGrid1.MasterViewInfo.SetColumnWidth(1, 150);

radVirtualGrid1.TableElement.SetColumnWidth(0, 300);

radVirtualGrid1.TableElement.SetColumnWidth(1, 150);

LoadData();

}

private void radVirtualGrid1_ColumnWidthChanged(object sender, VirtualGridColumnEventArgs e)

{

//This is always 100

int i = e.ViewInfo.ColumnWidth;

}

private void radVirtualGrid1_CellValueNeeded(object sender, Telerik.WinControls.UI.VirtualGridCellValueNeededEventArgs e)

{

if (e.ViewInfo == this.radVirtualGrid1.MasterViewInfo)

{

if (e.ColumnIndex < 0)

{

return;

}

e.FieldName = Foo.FieldNames[e.ColumnIndex];

if (e.RowIndex == RadVirtualGrid.HeaderRowIndex)

{

e.Value = e.FieldName;

}

else if (e.RowIndex >= 0)

{

e.Value = data[e.RowIndex][e.ColumnIndex];

}

private void LoadData()

{

Random random = new Random();

for (int i = 0; i < 10; i++)

{

Foo Foo = new Foo();

Foo.Me = i;

Foo.Yu = i;

data.Add(Foo);

}

this.radVirtualGrid1.RowCount = data.Count;

this.radVirtualGrid1.ColumnCount = Foo.FieldNames.Length;

}

public class Foo

{

public static readonly string[] FieldNames = { "Me", "Yu" };

public int Me { get; set; }

public int Yu { get; set; }

public int this[int index]

{

get

{

switch (index)

{

case 0: return Me;

case 1: return Yu;

default: return 0;

}

Suggestion

I suggest adding something to the RadTreeView that allows for getting which mouse button is being pressed on individual nodes. Maybe adding Button to the RadTreeViewEventArgs that returns a MouseButtons value.

For what I'm doing it won't make a huge difference, but it would help to know in certain circumstances.
