Hello,

I was wondering if anyone has any experience reloading a HostWindow. I can get the HostWindows I need from my DockWindows, gather the info I need from it, close the the HostWindow, make my new calculations, create a new HostWindow and add it to the Dock. However, this just puts the new HostWindow on the most recent document that had focus. What I want is for the new HostWindow to show up/refresh in the same spot. Does anyone know if this is possible?

This is what I was thinking; but it leaves the old HostWindow in the Dock and does not seem to add the "new" HostWindow to the dock.

//set the current window to a host window, if not a host window will return null

HostWindow hw = this.dockMain.DockWindows[i] as HostWindow;

//creates new form in hostwindow

hw = new HostWindow(createRightForm(tempModel, formName));

If you need anymore info from me just let me know. Thanks.

RadChart Programmatically

Is there a way to write this in winforms. I got this example from silverlight docs.

Private Function CreateChart_DefaultView() As Telerik.Windows.Controls.RadChart

Dim telerikChart As New Telerik.Windows.Controls.RadChart()

'Chart Title

telerikChart.DefaultView.ChartTitle.Content = "Year 2009"

telerikChart.DefaultView.ChartTitle.HorizontalAlignment = HorizontalAlignment.Center

'Chart Legend

telerikChart.DefaultView.ChartLegend.UseAutoGeneratedItems = True

'Line Chart

Dim lineSeries As New DataSeries()

lineSeries.LegendLabel = "Turnover"

lineSeries.Definition = New LineSeriesDefinition()

Dim dataPoint As New DataPoint()

dataPoint.YValue = 154

dataPoint.XCategory = "Jan"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 138

dataPoint.XCategory = "Feb"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 143

dataPoint.XCategory = "Mar"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 120

dataPoint.XCategory = "Apr"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 135

dataPoint.XCategory = "May"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 125

dataPoint.XCategory = "Jun"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 179

dataPoint.XCategory = "Jul"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 170

dataPoint.XCategory = "Aug"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 198

dataPoint.XCategory = "Sep"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 187

dataPoint.XCategory = "Sep"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 193

dataPoint.XCategory = "Nov"

lineSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 176

dataPoint.XCategory = "Dec"

lineSeries.Add(dataPoint)

telerikChart.DefaultView.ChartArea.DataSeries.Add(lineSeries)

'Bar Chart

Dim barSeries As New DataSeries()

barSeries.LegendLabel = "Expenses"

barSeries.Definition = New BarSeriesDefinition()

dataPoint = New DataPoint()

dataPoint.YValue = 45

dataPoint.XCategory = "Jan"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 48

dataPoint.XCategory = "Feb"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 53

dataPoint.XCategory = "Mar"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 41

dataPoint.XCategory = "Apr"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 32

dataPoint.XCategory = "May"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 28

dataPoint.XCategory = "Jun"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 63

dataPoint.XCategory = "Jul"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 74

dataPoint.XCategory = "Aug"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 77

dataPoint.XCategory = "Sep"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 85

dataPoint.XCategory = "Oct"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 89

dataPoint.XCategory = "Nov"

barSeries.Add(dataPoint)

dataPoint = New DataPoint()

dataPoint.YValue = 80

dataPoint.XCategory = "Dec"

barSeries.Add(dataPoint)

telerikChart.DefaultView.ChartArea.DataSeries.Add(barSeries)

Return telerikChart

End Function

I am well versed on using winforms chart control. I would like to do the same using RadChart. A few examples would be nice. Thank you.

Drag Drop Column to other Control

Hi

I need to "drag and drop" columns from a gridview to another control; for example a simple text box that just prints the header name when the column is droped on to it.

I have mined the posts here and the WinFroms demo, all implementing on the drag and drop service:
RadDragDropService dragDropService = this.radGridView1.GridViewElement.GetService<RadDragDropService>();
dragDropService.PreviewDragOver += new System.EventHandler<RadDragOverEventArgs>(dragDropService_PreviewDragOver);
dragDropService.PreviewDragDrop += new System.EventHandler<RadDropEventArgs>(dragDropService_PreviewDragDrop);

However, it seems that PreviewDragOver and PreviewDragDrop events are fired only when hitting on the listed members here:
http://www.telerik.com/help/winforms/t_telerik_wincontrols_ui_listcontroldragdropservice.html

and not a textbox or other generic container.

My question is: is there anyway i can allow and detect a column drop using some other code OR implement a new control that will implement the radservice

Thanks in advance.

[Solved] RadDropDownListEditorElement.Filter

I am using a licensed version of 2011.Q2 so it's not the latest but it's all that I have for the time being.

I set a filter callback for a ComboBoxColumn in the CellEditorInitialized event handler like this:

RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;

if (editor != null)

{

RadDropDownListEditorElement editorElement = (RadDropDownListEditorElement)editor.EditorElement;

editorElement.Filter = FilterWrappers;

}

This works fine. The problem is that I have another ComboBoxColumn with no filter on it. When I click in the first column and select a value and then click in the second column the filter method for the first column is called. It is called once for every item in the combo but the entries contain items from the first combo and items from the second combo. Why is this happening?

HtmlViewDefinition wrong header layout

Hi,
I have simple grid that contains 7 text columns with names column1, column2, ... column7.
When I apply following code I got layout that is shown in file grid1.png.

HtmlViewDefinition view = new HtmlViewDefinition();

view.RowTemplate.Rows.Add(new RowDefinition());

CellDefinition cell = new CellDefinition();

//row1

cell.UniqueName = "column1";

cell.RowSpan = 1;

cell.ColSpan = 2;

view.RowTemplate.Rows[0].Cells.Add(cell);

cell = new CellDefinition();

cell.UniqueName = "column4";

cell.RowSpan = 3;

cell.ColSpan = 1;

view.RowTemplate.Rows[0].Cells.Add(cell);

cell = new CellDefinition();

cell.UniqueName = "column5";

cell.RowSpan = 1;

cell.ColSpan = 1;

view.RowTemplate.Rows[0].Cells.Add(cell);

//row2

cell = new CellDefinition();

cell.UniqueName = "column2";

cell.RowSpan = 2;

cell.ColSpan = 1;

view.RowTemplate.Rows[1].Cells.Add(cell);

cell = new CellDefinition();

cell.UniqueName = "column3";

cell.RowSpan = 2;

cell.ColSpan = 1;

view.RowTemplate.Rows[1].Cells.Add(cell);

cell = new CellDefinition();

cell.UniqueName = "column6";

cell.RowSpan = 1;

cell.ColSpan = 1;

view.RowTemplate.Rows[1].Cells.Add(cell);

//row3

cell = new CellDefinition();

cell.UniqueName = "column7";

cell.RowSpan = 1;

cell.ColSpan = 1;

view.RowTemplate.Rows[2].Cells.Add(cell);

radGridView1.ViewDefinition = view;

Grid2.png shows what I want to achieve.
I am using 2011.3.11 version of Telerik.
Thanks

IP Mask doesn't produce valid IP address

I've just replaced a competitor's IP address mask input control with Telerik's Winforms 2011 Q2 and I'm disapointed with the functionality. Dropping the RadMaskedEditBox in place with MaskType = IP presented two problems:

When typing an IP address of 10.5.2.97 (with periods) it ends up '10 .5 .2 .97' in the box and requires custom reformatting to remove embedded spaces to make it into a valid IP address. Am I missing something?

Second and much more minor issue is that I could not find an easy way to make this controls blue border look the same as standard .NET controls of black; changing the Theme to ControlDefault did not work.

XValueMember

I want to switch over to the RADChart from a normal .net chart. The chart must be a bar chart with two series. It gets the XAxis Zfrom column 1 in the data table and the YValue from the second column.
This is the code I used for the .net chart

Me.Chart2.Series("MeterOne").XValueMember = "period"
Me.Chart2.Series("MeterTwo").XValueMember = "period"
Me.Chart2.Series("MeterOne").YValueMembers = "MeterOne"
Me.Chart2.Series("MeterTwo").YValueMembers = "MeterTwo"
Me.Chart2.ChartAreas(0).AxisX.Interval = 1

This code works perfectly but I don't know how to do this with the RADChart.

The referenced assembly could not be resolved because it has a dependency ...

Hello,

I get this warning since I have updated from Q3 2011 to Q1 2012.
Now everything works but how can I get rid of this warning ?
