Saving theme changes in code

We are looking to alter one of the standard themes, changing some of the details as well as the colours. Once complete, it will be necessary to make other themes that are the same but based on different colours.

I'm well aware of the usage of Visual Builder, so creating an initial theme is not a problem. I also have code that finds a theme in the currently loaded application, extracts all the images and alters the colours. I believe I can then create a clone of the theme and replace the images with the re-coloured versions, assuming the following code works

foreach (Telerik.WinControls.StyleRepository repository in theme.Repositories)

{

if (repository.ItemType == "Image")

{

foreach (Telerik.WinControls.PropertySetting setting in repository.Settings)

{

if (setting.Name == "Image")

{

Bitmap bmp = GetBitMap(repository.Key);

setting.Value = bmp

}

What I'm stuck with, is how to save the altered theme back to a tssp file.

Any help would be appreciated.

Thanks
Jason

DragDrop and EnableLassoSelection

Good day community,

MultiSelect = true;

MultiSelect = true; 
EnableLassoSelection = true;

multiselect does not work, because when I selected item and try grab it listview again tries to select rows.

Somebody knows how to fix it, or may be you have some working example.

Added check button to form, but instance of object not in telerik form1.designer.cs?

I added a new RadCheckBox from toolbox to my form. However, the object has not been initialized/instantiated in the Form1.Designer.cs code? So I have a button on a form, but I can't use it for anything.

How can I make sure that RadCheckBox that I added to the form has an object instance in the generated Telerik code? I could try to do it myself, but I note that this class states above the InitializeComponent() the following:

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()

So how to generate the code to make an object instance then? Please help. Thanks.

Make RadLabel Text Selectable For Copy and Paste

I'm displaying some information in a panel using the RadLabel. I noticed that you cannot select (i.e., drag and highlight) the RadLabel Text. Is there a setting so that the label can be highlighted for copy and paste purposes by the user?

Thank you!

Best Regards,

[Solved] Hide Available Filters drop down

Hi Telerik,

I'd like to be able to hide the Available Filters drop down list box for some GridView columns but not others when opening the Filter pop-up (Excel type filtering). Do you have some code I could use?

I would also like to be able to change the font for the resultant (after selecting a menu item from the Available Filters list) Radgrid Filter dialog value entry fields, if possible.

Thanks

Roger
