Custom RadGrid and skins / Special key press catch

Hello,

I have togive a custom behaviour to a RadGridView on the Delete or Up/Down key press.

Unfortunately, the RadGrid KeyPress doesn’t risen by the special keys.

So the only way I find to catch those keys press is to override the IsInputkey function so tomake my own control witch extends from the telerik radGrid.

public class CtrlRadGrid : Telerik.WinControls.UI.RadGridView

{

public CtrlRadGrid()

:base(){}

public delegate void InputKeyEvent(Keys keyData);

public event InputKeyEvent InputKeyOccurs = null;

protected override bool IsInputKey(KeyskeyData)

{

if (InputKeyOccurs != null)

{

InputKeyOccurs(keyData);

}

return base.IsInputKey(keyData);

}

All works great, my event is raised by all the keys, and all the grid keep isfunctionality… except the skin…

I think that there must be a control on the name of the class…

So is there a simple way to apply the skin on my own control witch extends from radGrid?

Is there a simple way to catch the keyPress from special keys?

Exception with RadPanelBar

I was previously using the December 3rd release of Rad Controls, I used the project updater tool (I like the new recursive feature, that saves me a lot of time) and compiled without a hitch.

However, upon clicking on my RadPanelBar now I get this exception:

System.InvalidCastException: Unable to cast object of type 'Telerik.WinControls.UI.RadPanelBar' to type 'Telerik.WinControls.UI.RadTabStrip'.
   at Telerik.WinControls.UI.RadTabStripContentPanel.OnEnter(EventArgs e)
   at System.Windows.Forms.Control.NotifyEnter()
   at System.Windows.Forms.ContainerControl.UpdateFocusedControl()

If I hit continue and click on the same object again, it does select the RadToggleButton element.

Before upgrading this error did not occur.

Exporting From Grid in Windows Service

Hello,

I've got a windows service that I'd like to have an excel spreadsheet produced in. In the client, this is done via the Grid view Exporter. However, in the windows service, there are obviously no forms, so in order to do it this way, I would have to instantiate the RadGridView element, set its properties programmatically, set the datasource, and hope that it will be able to export a nicely formatted spreadsheet. When trying this, I was unable to get the grid's columns and rows to populate. Here is how I currently set it up:

                    grdResults.BackColor = System.Drawing.Color.White;         
                                        //          
                                        //          
                                        //          
                                        grdResults.MasterGridViewTemplate.AddNewRowPosition = Telerik.WinControls.UI.PinnedRowPosition.Bottom;         
                                        grdResults.MasterGridViewTemplate.AllowAddNewRow = false;         
                                        grdResults.MasterGridViewTemplate.AllowColumnChooser = false;         
                                        grdResults.MasterGridViewTemplate.AllowDeleteRow = false;         
                                        grdResults.MasterGridViewTemplate.AllowEditRow = false;         
                                        grdResults.MasterGridViewTemplate.AllowRowResize = false;         
                                        grdResults.MasterGridViewTemplate.AutoGenerateColumns = true;         
                                        grdResults.MasterGridViewTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;         
                                        grdResults.MasterGridViewTemplate.EnableGrouping = false;         
                                        grdResults.MasterGridViewTemplate.ShowFilteringRow = false;         
                                        grdResults.MasterGridViewTemplate.ShowRowHeaderColumn = false;         
                                        grdResults.MultiSelect = true;         
                                        grdResults.Name = "grdResults";         
                                        grdResults.ReadOnly = true;         
                                        grdResults.ShowGroupPanel = false;         
                                        grdResults.Size = new System.Drawing.Size(684, 461);         
                                        grdResults.TabIndex = 15;         
                                        grdResults.TabStop = false;         
                                        ((Telerik.WinControls.UI.GridTableElement)(grdResults.GetChildAt(0))).AlternatingRowColor = System.Drawing.Color.FromArgb(((int)(((byte)(222)))), ((int)(((byte)(255)))), ((int)(((byte)(222)))));         
                                        ((Telerik.WinControls.UI.GridTableElement)(grdResults.GetChildAt(0))).RowHeight = 18;         
                                        grdResults.Size = new Size(1000, 700);         
                                        grdResults.DataSource = objRecordList;         

After the datasource is set, there are still no rows or columns, even though this should produce 67 rows and four columns. Is there an easier way to produce the desired spreadsheet from my list of objects? Alternatively, is there something I can do to get the grid to behave better so I can leverage the build-in exporter?

Thanks!

Jeremy

IPhone Skin

Hi,

I am working on a winforms version of the IPhone menu from telerik ASP.NET. I took the Background an mad it transparent.
After that I took a titlebar and made it nice so it fitted in the top section of the picture. That gave me window and drag functionality.
Found a action button for the bottom center. All nice.

But now in the main window I need some action.
I started to work with a listbox and my approach is to ajust the appearance with the telerik Theme Builder and test.

My first problem / chalenge is that when I open my existing myStyle.XML file and make some changes, save the file and test, some previous changes seem to have dissapeared ????

My second chalenge is more a question if there maybe exist already something like this or Is somebody interested in assisting a littlebit to achieve a winforms version of the Telerik ASP.NET IPhone demo ???
Maybe this could look nice in the telerik winforms demo as well ???

Regards,

Rick Rehorst

How to create a tabbed MDI with default-system look?

I'm trying to create a simple tabbed MDI application. It won't even have dockable toolbars or anything, just a tab bar with open documents. I could do a traditional MDI, but I think that tabbed MDI is easier to use and more modern.

I would also like my application to retain the "default system" look that users are familiar with instead of using fancy color schemes and custom control styles.

How can I best achieve this? I tried the RadDock, and while it does provide the tabbed MDI part, the theming support for it is still incomplete and I can't get the standard look. I could also try to use a simple RadTabStrip, but for that I can't find any options to add a "close" button next to each item.

What would be the recommended way?

Implement windows system themes

Hi,

I am building an application that has a need to implement themes in such a way that they will be synchronized with system themes (coloring scheme). The problem is when I used Telerik controls and use any of available themes on them, the controls on application would not take any effect when Windows themes are changed. I used another UI component that provides a theme named "system" that applies the current Windows theme on the application and when system theme changes it is also reflected in the application.

I want to know if the same behavior can be produced by using Telerik controls? Please let me know if this is possible or any work around is available for this case.

Haroon

300.00      Visa                    2

The pie chart has to display Amount of the respective tendertype.

Plz help me with how to code and display in Windows application using VB.Net.

Thank you in advance.
