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());

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

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.

Chart (obsolete as of Q1 2013)

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 ?

Warning 3 The referenced assembly "Telerik.WinControls.UI.Design, Version=2012.1.301.40, Culture=neutral, PublicKeyToken=5bb2a467cbec794e, processorArchitecture=MSIL" could not be resolved because it has a dependency on "System.Drawing.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project.

Thank you.

[Solved] iTunes-like grid

Hi guys,

I'm trying to create a grid similar to the iTunes one (in Artist mode). This is just a regular grid (no problem here), but the first colum doesn't show a row for each record, but an image for all the records that share this image (in this case, the cover image for all the tracks in an album). I have attached an screenshot to show what I'm talking about.

My question is, is it possible to implement this with GridView and, if so, how? If not, and although I know this is a bit off topic, which controls combination could I use to replicate this interface?

Thank you very much.

[Solved] RibbonBar RasSplitButtonElement behaviour

Hi All,

I've got a WinForms app with a RadRibbonBar and various groups of buttons, which all work fine ... apart from one. I've just added a Split button as I need to have additional options when "Previewing", but don't seem to be able to use the main button part as a normal Click event, without the sub-items showing, and clicking on the "Arrow" to show sub-items causes a click event on the main button as well.

Is there a way to stop the RadSplitButton from showing the dropdown of child items when clicking the "main surface" of the button (as this would be the normal action), and then ONLY show the sub-item collection when you click on the Arrow, as with Microsoft behaviour for the Ribbon Bar?

Thanks in advance,
Paul
