Hey,

Just wanted to inform from small issue with latest version of telerik.

When ever we try to add new radform into our project, VS2010 gives error and form aint added. We tested it out littlebit and 3 of our programers had this error and 1 didn't.
Ofcourse there is easy workarounds (add new normal form and swap it into radform, copypaste old one etc), but still wanted to inform you about it.

Cheers,

Toni


Here is the full error from error message:

Error occurred while running wizard.

Hello.!

I am a user who uses your Telerik library.
Currently, I have been programming CharView on Winfom.
In case of the program that I develop, Whenever I click a button, it draws a chart then BindingList’s data is increasing continuously.
What I want to do is that let the Scroll bar be displayed when the number of data is over 20.
However, my program does not display Scroll bar when that happens.
My code is the following.

public partial class Form1 : Form
    {
        private BindingList<SampleData> _collectiontempsite1;
 
        public Form1()
        {
            InitializeComponent();
        }
 
        private void Form1_Load(object sender, EventArgs e)
        {
            _collectiontempsite1 = new BindingList<SampleData>();           
 
            radChartView1.ShowTitle = true;
            radChartView1.Title = "Sample";
 
            ClearChart();
            DrawChart();
        }
 
        private void ClearChart()
        {
            radChartView1.Series.Clear();
            radChartView1.Axes.Clear();
        }
 
        private void DrawChart()
        {
            CategoricalAxis horizontalAxis = new CategoricalAxis();
            horizontalAxis.PlotMode = AxisPlotMode.OnTicksPadded;
            //      horizontalAxis.LabelFitMode = AxisLabelFitMode.Rotate;
            //      horizontalAxis.LabelRotationAngle = 270;
            horizontalAxis.LabelInterval = 10;          
 
            LinearAxis verticalAxis = new LinearAxis();
            verticalAxis.AxisType = AxisType.Second;          
            verticalAxis.LabelInterval = 2;          
 
            CartesianSeries series1 = null;
            series1 = new LineSeries();
            series1.LegendTitle = "site1";
            series1.PointSize = new SizeF(5, 5);
            series1.HorizontalAxis = horizontalAxis;
            series1.VerticalAxis = verticalAxis;
            series1.BorderWidth = 2;
            series1.CategoryMember = "Time";
            series1.ValueMember = "Temp";
            series1.DataSource = _collectiontempsite1;           
            //series1.ShowLabels = true;
            series1.CombineMode = ChartSeriesCombineMode.None;
 
            radChartView1.Series.Add(series1);
            radChartView1.Area.View.Palette = KnownPalette.Summer;
 
            radChartView1.VerticalScroll.Enabled = true;
            radChartView1.VerticalScroll.Visible = true;
            radChartView1.HorizontalScroll.Enabled = true;
            radChartView1.HorizontalScroll.Visible = true;     
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
            Random r = new Random(DateTime.Now.Millisecond);
 
            string strCurrentTime = DateTime.Now.ToString("hh:mm:ss:ffff");
            double dTemp = Convert.ToDouble(r.Next(70, 120));
            _collectiontempsite1.Add(new SampleData(strCurrentTime, dTemp));
        }
    }



Please respond to what I concern. Thank you.

I'd love to use the RadCollapsiblePanel to provide drop down buttons in my application on certain menus, but my buttons currently are square. and I can't seem to modify the button shape in the panel without using the ControlSpy. Even then it seems odd that there is no "square" button shape to select and I have to make a custom shape for something so common.

My main problem at this point, however, is that any time I set the button element AutoSize to false, the button vanishes at runtime. I attached an image of how it looks at design time. I am able to use a larger image and resize the button, change the background, border, etc. I can't figure out how to make it square and at runtime, the button is gone and nothing in that area responds to a click.

Please could someone let me know if it is possible to have a background image set to a specific cell on every row, but to also have a label/TextBoxCell in that cell too?

Any examples would be great.

I know this is posted somewhere here, so my search phrases must me horrible..

New to api, looking at how a can assign a form a theme during it's creation.   Want to be able to switch themes based on how a form is called.

I created a form which implements RadForm

Thanks

Hi guys,

I am trying to do a few style changes to the scrollbar. I've attatched an image of how it looks currently.

1) There is a border on the whole left hand side of the control. I can't find anywhere in the element editor. Please can someone let me know which property I need to change to hide this?

2) You will notice I have take away the arrows. I want the scrollbar to not have arrows. But the area in which the arrows sit is still visible, can I remove this extra space?

Many thanks,

J

Hello,
     i'm using a RadListView in DetailsView mode.

When i insert an element in the Items collection of the RadListView, the Vertical-scrollbar's thumb remains snapped on the bottom to ensure the visibility of the last item. Items are inserted at the speed of almost one item per seconds.

I would like to control this behaviour, because (as all of the most common software do) i would like to stop refreshing the scrollbar position when the user click on the scrollbar or scrolls the wheel up to check more accurately an item.

Actually i'm doing this:

item insert:
private void ListView1AddLogMessage(string message, DateTime? dateTime)
  {
      if (dateTime == null)
          dateTime = DateTime.Now;
 
      if (userClicked)
          this.radListView1.BeginUpdate();
 
      LogList.Add(new LogItem { Info = message, Timestamp = dateTime.Value });
 
      if (userClicked)
          this.radListView1.EndUpdate();
  }


The userClicked variable is a bool that it's initialized like
bool userClicked = false;


and when I configure the ListView i bind the click and scroll events to simple functions that turns userClicked to be true, so that no update is performed.
void ThumbElement_Click(object sender, EventArgs e)
{
    userClicked = true;
}

But there are two main problems.
1) I would like to create an event similar to this one, for example if the user scroll wherever on the radlistview, probably he wants to stop the autorefresh, as it would probably be if he clicks on an element.
2) i would like to restore programmatically the auto refresh(plus the scrollbar-thumb autosnap to the bottom) when the users drag the thumb to the bottom of the scrollbar track


This seems to be a common behaviour to me for other application but i can't implement it in this case.

Thanks

Here is an interesting situation :

- I use a RadDock containing 2 ToolWindows, docked in a shared TabStrip.
- I change win1's dockstate to 'floating'.
- I change win2's dockstate to 'autohide'.
- I save RadDock's configuration in an XML file.
- I use RadDock.Hide().

Now, to avoid a possible flicker on the screen, I wish to load the previous XML file before showing RadDock again. After RadDock.Show(), both ToolWindows are in a 'autohide' state ! If I 'unpin' win1, it gets back to the 'floating' state. But double-clicking on its title-bar won't dock it any more.

Is there a way to safely load a XML configuration while having RadDock hidden ?
