.Net's DataGridView allows the Ctrl-Home / Ctrl-End keys to go to the top - left Cell / bottom - right Cell in the grid.  In RadGridView, those keys do the same as the Home / End keys which go to the first / last Cell of the Slected Row.  I couldn't find any combo of Home, End, Page Up, Page Down, Up, Down, Left or Right with the Shift, Ctrl or Alt modifiiers that would go to the top / bottom of the grid.  Are there top  / bottom of grid keys predefined?  Is there a way to override the standard navigation keys?

When editing the filter value on a Date column:

1. It cuts off the left part of the date regardless of how wide I make the Column.

2. It always requires editing in a "ToLongDateString" fromat (aka "D", aka "dddd, MMMM dd, yyyy") vs. (oh, I don't know, call me crazy, but maybe perhaps) the format specified by the user in your  "FormatString" Property of your "GridViewDataColumn" Class.  ;) This is: a) non-intuitive as it may not (and probably usually does not) match the format used in the data columns since the "D" format is rarely used especially in tables where horizontal space is at a premium, b) may be (and probably usually will be) too wide to fit in the Column (even if #1 is fixed) even when the Column is wide enough to fit the Data Row values which are probably usually in a much shorter format like "MM/dd/yy" or "MM/dd/yyyy" (at least for us weirdos in B.F.E. USA ;) anyway).

Hi

I am adding items to listbox like this (from a background worker thread).

  dim d as New AddDelegate(AddressOf radListBox1.Items.Add)
  dim item as New RadListBoxItem
  item.Text = "some text"
  dim args() as Object = {item}
  radListBox1.Invoke(d, args)

However I sometimes get an error after some items are added (I think it
is also if an item is selected in the listbox and if I change hide and show the form). This is thrown on the main form. If tried using the BeginUpdate and EndUpdate method as well, but that doesn't seem to make a difference.

This is the message
    "Parameter is not valid."

Hi Telerik

Can you give us a example how to implement the scroll bar to the telerik and Micorsoft Control? We can't find it User manual.

And  when we try to use the telerik control, we found "flicker" is a big problem at many place. Do you have anu good solution to make the change between the different control more smooth?

Thank you

hi,telerik,
   I'm a telerik user ,i encountered a problem when i used the gridview Control in my gui,i have two question as following:
  1>i just want to set the height of the header in the gridview,but i can't find out  which property should be set,could u pls give me an example  about how to implement it ?
  2>and another question ,when you set up a relation in the gridview ,and the childtable will be displayed in the current record,you will find a plus(+) image in the first cell ,i want to replace the plus(+) image with my image ,and how to implement ?
 thanks for you help and support

 

Hi,

Before I beat myself silly,  Is it possible in WinForms to have nested MDI parents. Or in other words a MDI child that is also a MDI Parent.

Hello,
In design I am adding Item 10 to TabStrip collection.  I have named it TabOnline, however the ContentPanel name is TabItem1.  However if I select the tab and then the content panel, it is correctly called TabOnline.  Also, in the code it does not know the tabitem TabOnline.  I've tried deleting and readding the item and tried a different name too.  I've even tried keeping the tab the default of TabItem1, but it still is not available in code.
I did install Q3 yesterday.
Thanks.

I'd like to put in a vote for a ListView control , I myself and many people I know still find using listviews very useful especially with their capacity for multiple style views. Possibly also a TreeListView like the silverlight suite has too ?

I'd love to see versions for winforms and for wpf .

I've got an empty winform where I want to drag and drop the new radgridview Q3 2009. But when dropped I'm getting a messagebox with the following error:

"No such property registered: IsMouseOverScrollBar, Telerik.WinControls.UI.RadScrollBarElement"

Before doing this I inserted all .dll files into visual studio 2008 into a new tab called "Telerik Q3 2009". I've got another tab called "Telerik Q1 2009" with those controls that I'm currently using in my prototype.

Now I looked in the folder with the new dll"s, trying to find this element, but couldn't find it. I also didn't find this element in the "Choose Items". So I don't think that I missed a dll file to import into visual studio.

Any solutions?
Thanks
