[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.

[Solved] combobox textbox not aligning correctly

Hi,

I have an issue where I had originally set the combobox textbox alignment to the right with:

// **** Align Drop Down Box Text to Right

revPurgeCodeDropList.MultiColumnComboBoxElement.TextBoxElement.TextAlign = HorizontalAlignment.Right;

addPurgeCodeDropList.MultiColumnComboBoxElement.TextBoxElement.TextAlign = HorizontalAlignment.Right;

scrapCodeDropList.MultiColumnComboBoxElement.TextBoxElement.TextAlign = HorizontalAlignment.Right;

scrapRsnDropList.MultiColumnComboBoxElement.TextBoxElement.TextAlign = HorizontalAlignment.Right;

// ************************

And it worked correctly. But then I decided I didn't want the user to be able to input anything, only select from drop down. So I added raddropdownstyle.dropdownlist:

// **** not allow use to type in

scrapCodeDropList.DropDownStyle = RadDropDownStyle.DropDownList;

scrapRsnDropList.DropDownStyle = RadDropDownStyle.DropDownList;

revPurgeCodeDropList.DropDownStyle = RadDropDownStyle.DropDownList;

addPurgeCodeDropList.DropDownStyle = RadDropDownStyle.DropDownList;

// ************************

The raddropdownstyle.dropdownlist worked, but the alignment isn't working any longer. I tried to put this before and I tried after before it's the same. Am I doing something wrong? Here's what I have now:

// **** not allow use to type in

scrapCodeDropList.DropDownStyle = RadDropDownStyle.DropDownList;

scrapRsnDropList.DropDownStyle = RadDropDownStyle.DropDownList;

revPurgeCodeDropList.DropDownStyle = RadDropDownStyle.DropDownList;

addPurgeCodeDropList.DropDownStyle = RadDropDownStyle.DropDownList;

// ************************

// **** Align Drop Down Box Text to Right

revPurgeCodeDropList.MultiColumnComboBoxElement.TextBoxElement.TextAlign = HorizontalAlignment.Right;

addPurgeCodeDropList.MultiColumnComboBoxElement.TextBoxElement.TextAlign = HorizontalAlignment.Right;

scrapCodeDropList.MultiColumnComboBoxElement.TextBoxElement.TextAlign = HorizontalAlignment.Right;

scrapRsnDropList.MultiColumnComboBoxElement.TextBoxElement.TextAlign = HorizontalAlignment.Right;

// ************************

Different Decimal Formats in Same Column

A gridview (read only) has a quantity column that is normally formatted with zero decimal positions. Now we have a situation where the values in some rows will have significant decimal values and others will not. Can I set the decimal format of individual cells (hoping that CellFormatting event is part of that solution)?

Hide Toolbar on left hand side

Hi all,

I just downloaded the Telerik UI for Winforms 2018_2_621 and started "tinkering" around with the RadImageEditor control for a specific project I am currently working on for work. I was wondering, is there a way to "hide" or "disable" the buttons on the toolbar on the left hand side of the image editor? Or (perhaps the most ideal for me) is there a way to completely hide the toolbar altogether on the left hand side?

I thought this would be a simple "enable" or "disable" on a property of the control, but I can't seem to find any documentation on this matter. Thank you and I look forward to the response.

Paste from excel in to "Add New" row

Im looking for a way to copy multiple rows from Excel and paste them in to an empty grid. There doesnt seem to be a way to do this by default? How would I go about implementing this. If i add a blank row I can then paste the multiple rows but then the default values for the other columns dont get filled in.

With a normal grid I used the following code: This would also add the "Default Values" for the other columns as well.

private void PasteClipboard()

{

char[] rowSplitter = { '\r', '\n' };

char[] columnSplitter = { '\t' };

// Get the text from clipboard

IDataObject dataInClipboard = Clipboard.GetDataObject();

string stringInClipboard = (string)dataInClipboard.GetData(DataFormats.Text);

// Split it into lines

string[] rowsInClipboard = stringInClipboard.Split(rowSplitter, StringSplitOptions.RemoveEmptyEntries);

// Get the row and column of selected cell in grid

int r = ColumnsGrid.SelectedCells[0].RowIndex;

int c = ColumnsGrid.SelectedCells[0].ColumnIndex;
