Hello,

am I missing something or there's no way to set the autocomplete mode to a PropertyGridDropDownListeditor?

 

var editor = new PropertyGridDropDownListEditor();
editor.DropDownStyle = RadDropDownStyle.DropDown;
// nope:
// editor.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

 

Thanks.

Hi,

Is there an event that fires when the user is moving an item in the timelime? I would like to check if the item overlaps with other items that depend on the parent and cancel the drag action if there is any conflict.

 

Thanks

Blas

OS WINXP
C# .Net 4.0
Telerik 2012.2.726.40

I am displaying/editing RadTreeView Nodes in a RadPropertyGrid.
I'm having a problem with the properties being rounded to two decimal places, where I want to support up to four decimal places.

So lets say I have a property named Length:
/**
 *\brief Gets or sets the name variable.
*\
*/
[DefaultValue ("New User Home"),
DescriptionAttribute ("Name of this User Home Object."),
CategoryAttribute ("(General)")]
public Double Length
{
      get { return Math.Round(_length, 4); }
      set { _length = value; }
}

If I enter 23.4567 into the property grid it rounds it to 23.46.

From this msdn thread I found that you can wrap it into a string and handle the number of decimals from there.
The problems I have with this are:

  1. I shouldn't have to use a cheap trick to determine the accuracy of a number.
  2. When I save the node there are now two lines of XML just for one property, the property that is called in my code, and the wrapper.

What is the correct way to determine the rounding performed on all doubles/floats.

Hi.

I am using the "Copy" command from the right-click menu and it works OK in copying selected cells to the clipboard and then pasting into another program.

However, I want to copy the entire grid, including column and row headers.

The headers cannot be selected.

Is there a way to copy the entire grid to clipboard?

Sound becomes disabled in other applications (eg youtube, netflix) when webcam is active eg taking snapshot.

Ive observed this using a bluetooth headset and a bluetooth speaker but it doesn't happen if my (HDMI) monitor speaker is outputting sound.
