Hi Guys,

I'm hoping that someone can help me with this.

I have a Main business Object that i display on the property grid and that works fine. However I would like to add a business object collection and have it display as a property on the Mani Business Object, so that when the Main business Object is loaded on to the property grid the collection displays as a child.

This works fine when i use a standard windows property grid. So i was wondering if i missed something?

Your help in this will be greatly appreciated.

regards

Bongani

Hello,
     I want to dynamically change the type of cell in the current row from TextBox to RadDropDownList.  I need the DropDownList to already be populated so I created one in the designer view and just made it not visible.  How do I populate it though?  I can't seem to access it in code.
Thanks!
Jason

I have implemented my custom column, inheriting from GridViewDecimalColumn. The code looks like this:


 I am adding a DynamicDecimalColumn by using code like

The column is defined as filterable. When I start filtering by typing a filter text, the system is using a "contains" filter (LIKE) by default, and so I get an error. When I open the context menu to change the filter, the "Contains" filter ist not available, as expected. How can I change the initial filter by code, as I would like the "Equals" filter as the initial filter ?

Dear Telerik Team,
I got gold historical data like this:

"2011-07-07 15:08:39" - "Valid"
"2011-07-07 15:09:20" - "Valid"
"2011-07-07 15:10:39" - "Invalid"
"2011-07-07 15:11:26" - "Valid"

and so on.

When I import an html document that contains <Hn> tags they get converted to <p> tags with css styles to manage the formatting when they are subsequently exported/saved as html. Is this the planned behavior? I looked at the equivalent behavor for <li> tags and their identity is retained.

I would certainly vote for the retention of <Hn> tag identity!

If I can combine two questions into a single post - any guidance you can provide on how to set a heading using the RichTextBox would be appreciated. I'm looking for the equivalent functionality to the drop down list that permits you set the style of the paragraph to the associated stylesheet classes or to defined tags, i.e., <Hn>

Thanks for the prompt respones to forum posts!

I really want to use the RichTextBox in an application I'm finalizing but I have been stymied by the issues I've enumerated below. Firts of all let me provide some background on my particular use so that you can determine if the scenario applies broadly.

Scenario: RichTextBox is used to create Html fragments that are integrated into a finished document where formatting (headings and indents) are adjusted by where the fragment appears in the documents outline hierarchy. Fragments are created as if they are at level 1 (one) and the indent level is programmatically adjusted by where in the outline the fragment appears.

To the best of my knowledge...

1. HtmlFormatter translates Hn tags to <p> tags presents a challengs.
2. Import process defines classes using some sort of internal naming approach. (I'd like associated classes and their name to be retained.)
3. Providing an embedded stylesheet within an imported html document is not used.
4. StyleDefinition(s) do not provide an ability to "name" the definition so that they can be programmatically assigned to a paragraph or span. (There may be a StyleProperty that supports this but I could not determine it.)
5. I was pursueing the approach of wrapping the existing HtmlFormatter object and extending its utilty but many of the underlying classes are exposed at the Friend level versus Public level which prevents this approach

My application is very concerned with **structure** while the RichTextBox is very concerned with retaining **style**. Whle addressing my point 1 above solves all my concerns points 2 - 5 I believe would be of value to other implementers.

I'm going to have to fall back to using the web based Editor (which presents its own set of restrictions) but I will anxiously be watching developments in the RichTextBox as I believe that once finalized it will be an excellent product.

Hi,

   I'm creating a window with a GridView 01 where I need open other window with a GridView 02 for select some values and set in GridView 01 the selected values. I'd like know how to do set the selected values of GridView 02 to GridView 01?
Image with a sample attached.

Thankful for attention!
  

Hi 

I have an application that has been written over the past 4 years. My company has now purchased RadControls for WinForms and so I am going to slowly convert it screen by screen.

In the meantime though I have a function that is called by all current screens.

SetupScreen(byval frm as form)

I want to do different actions if the form is a Telerik RadForm. How do I know if the frm passed to my function is the standard form or a telerik form? Hopefully without changing the signature of my function "SetupScreen"

Cheers

We Have thread deadlock problem since we upgraded to Telerik 2010.3.
In our application we have a form which is initialized in the background. in some cases, which we can't exactly define the back thread and the main thread lock one each other and the application gets stuck.
The call stack shows that the thread is stuck at Telerik function

We'll appriciate your help as quick as possible.

Going by your examples, I set the AllowDrop for the RadListControl to true. I also have set the SelectionMode to MultiExtended. Also, per your example in the TreeView section, I coded the RadListControl's MouseDown event to call the DoDragDrop() method. However, now I can not select rows with the mouse. I can select extended with the arrow keys and shift key, and I can drag them into the TreeView, succesfully. It's like the mouse only works for Dragging, it won't even control the scroll bar in the RadListControl.

Basically I did everything you wrote in the Treeview "Enabling Drag and Drop" section, except I used a RadListView instead of a Windows listbox for the source control.  It works with a Windows listbox, but I would like to use the Telerik version.

Help Please.
