The RadWizard has a couple of buttons by default added to the CommandArea of the RadWizard: the BackButton, the CancelButton, the FinalButton, the HelpButton, and the NextButton...

I would like to add another (custom) button (which has the look and feel of the buttons I just mentioned above / different text) which launches off a process and eventually returns.... I was wondering if there is an easy way to do this? I've been messing around for a few hours now and I'm able to add a "Test" button; however, it is not in the correct order (I would like it to appear between the Next/Back buttons and it's size is being changed during runtime (I'm assuming this is something to do with the CommandArea object's LayoutManager?)) - see the attached screenshot

I've also wondered if re-purposing (changing the text) of one of the buttons I've hidden may do the trick.... I have a few problems with this:

It seems a bit "hackish"
I'm not sure if/how many more buttons we will need to add in the future; however, I do know there's the possibility of running out of buttons to "re-purpose" if we go above three custom buttons

Any help / suggestions would be greatly appreciated.

Regards,
Carl

Adding new node to TreeView with filter applied ealier make the node appears twice

The problem may be reproduced in example application in TreeView/First Look in v 2012.1.321.20.
The scenario is as follows:
-enter some text as a filter
-delete text - filter should be off
-add new node by context menu -> "New Node" appears twice in the tree view

I spent a moment with debugger and i found that in TreeNodeView.UpdateView()
when the filter is off the state[StateFiltered] is not set to false, that make the
following TreeNodeView.Insert() add new node to the "view" and "nodes" collection
which refers to the same list.

Is this a known bug? Is there any workaround for this problem?

Resizing an appointment to be multiple days

Hi,

To get the multi-day behavior we are after when using RadScheduler, through some other forum posts, we found that we can set the ShowAllDayArea to false on the WeekView, and it does what we want. (RadScheduler.GetWeekView().ShowAllDayArea = false). When dragging to select cells, you can click on say Monday at 2:00 pm, and drag to Wednesday at 10:00 am, and define an appointment for that time. Great.

However, we can't resize an existing appointment to extend it to multiple days. So, if we have an appointment from Monday at 2:00 pm to Monday at 5:00 pm, we can drag the bottom of that to extend to Monday at 9:00 pm, but if we keep dragging to the right, it does not extend to Tuesday, etc. And likewise, if we try to resize an appointment that was already multiple days, we can't change which days the start or end are on through drag resizing. Whatever end you're dragging stays confined to the same day.

Is there anyway to enable the behavior to be able to resize to multiple days? We're using RadScheduler from Q2 2010 SP2.

Thanks!
-Daniel

CommandBar theme height

I just started working with the controls. And now i'm trying to find a way to change the height of commandbar control in theme editor. I think I checked everything but did not find a way to it. ALthough, i can see the the height is different in office2010 and office2007 themes. Can someone point me to the right way to do that customization?
Appreciate your support.

[Solved] Changing "0.00" into "" - Removing Zero Values

Good Morning Telerik Community,

I am attempting to format certain cells in my RadGridView to remove the text from a cell if its value == 0.0 ... It works but for what ever reason it is Very slow and takes about two seconds to continue... Am I doing something wrong?

Note: The extension method String.ToDecimal() attempts to convert the string to a decimal and returns a decimal?, null if it failed. I've replaced it with a standard Convert.ToDecimal() and it made no difference..

private Boolean CellFormatting { get; set; }

private void gridGLDetails_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)

{

if (!CellFormatting && (e.Column.HeaderText == "Credit" || e.Column.HeaderText == "Debit") && e.CellElement.Text.ToDecimal() == 0.0M)

{

CellFormatting = true;

e.CellElement.Text = "";

CellFormatting = false;

}

[Solved] Cell formating and sorting problem

Hi,

I have a problem when formatting the background color of a row and then sorting the grid view. I have a gridview with 10 columns. Depending on a condition I color the background on some rows. See code. This works initially fine. But when I now sort the grid view more and more rows are colored. If I click a lot of times on different column headers all rows execept one have a formatted background. I'm surely forgot something to do, to make this work.

private void RadGridView1CellFormatting(object sender, CellFormattingEventArgs e)

{

if (!String.IsNullOrEmpty(e.CellElement.RowInfo.Cells["Bearbeitungsfrist"].Value.ToString()))

{

var bfrist = (DateTime)e.Row.Cells["Bearbeitungsfrist"].Value;

if (bfrist < DateTime.Now)

{

e.CellElement.DrawFill = true;

e.CellElement.ForeColor = Color.White;

e.CellElement.NumberOfColors = 1;

e.CellElement.BackColor = Color.Coral;

}

Thanks for your help,
Michael

Point Chart - Point Center moves with point size

Hello,
I have a data-bound point chart that I'd like to change the point size of some points on. Ideally I'd like to have the point size read from a data column like the bubble chart, but I can't figure out how to do that. I have some code that goes through the Chart Series and updates the point size, but the points shift off their center point.

My chart is plotting percentages for a variable number of people. I want to use the bubble size to show relative sample sizes in the percentages.

I've tried the Bubble chart, but it is difficult to get rid of ovals, especially when the chart resizes. There are a variable number of items in my chart, so it is not a grid. The bubble chart also has a problem when there is only one item in the chart. I've decided that a bubble chart cannot do what I want and a point chart is closer.

Is there a way to put the point back on its center coordinate? Or a way to use the bubble chart and get bubbles to be a pixel size (like the point chart) rather than use the coordinate system for plotting?

I'm using version 2011.3.11.1219 with the .NET 2.0 framework (Visual Studio 2010). My development machine is a Windows 7 - 64bit computer.

I've attached sample code that reproduces the problem. My real code loads data from a database and contains variable numbers of people.

Form1.cs

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.Charting;

   dtPage.TableName = "ChartData";
   dtPage.Columns.Add("Name", typeof(String));
   dtPage.Columns.Add("Completion", typeof(Double));
   dtPage.Columns.Add("PointRadius", typeof(Double));

   DataRow row = dtPage.NewRow();
   row[0] = "Person1";
   row[1] = .80d;
   row[2] = 20d;
   dtPage.Rows.Add(row);
   row = dtPage.NewRow();
   row[0] = "Person2";
   row[1] = .65d;
   row[2] = 40d;
   dtPage.Rows.Add(row);

radChart1.DataSource = dtPage;
radChart1.DataBind();

   //Force update of point sizes. We can't seem to do it from the bound data.
   foreach (ChartSeries series in radChart1.Series)
   {
    if (series.Type == Telerik.Charting.ChartSeriesType.Point)
    {
     series.Appearance.PointDimentions.AutoSize = false;
     foreach (ChartSeriesItem seriesItem in series.Items)
     {
      DataRow drow = dtPage.Rows[seriesItem.Index];
      double radius = (double)drow["PointRadius"];
      seriesItem.Appearance.PointDimentions.AutoSize = false;
      seriesItem.Appearance.PointDimentions.Height = Telerik.Charting.Styles.Unit.Pixel((float)(radius * 2));
      seriesItem.Appearance.PointDimentions.Width = Telerik.Charting.Styles.Unit.Pixel((float)(radius * 2));
      //(seriesItem.PointAppearance.Position).Auto = false;
      //(seriesItem.PointAppearance.Position).AlignedPosition = AlignedPositions.Center;
     }
    }
   }

}
}
}
