Hello,

I have forms inside document panes. The panes are created automatically for each MDI child form. I don't understand why document panes are working with form events. Isn't it logical that the little X button in the top right corner of the document pane causes the form to close? As a replacement for the normal close button of the form. If I don't want the form to close, just hide, I can always intercept the FormClosing event and cancel it, right?

The way it works now is very bad:
1) When I manually call the form Close method , the form closes, but the pane stays open. It should close as well since it is obviously not needed anymore.
2) When I click the document pane's X button it disappears, but the FormClosing/FormClosed events do not fire.

I've also read another post related to Activate and Deactivate events not firing and you say it's by design. I don't understand why it should be this way. Without the proper plumbing I have to write a lot more complicated code just to do all this basic stuff.

Can't you extend the document pane logic to support MDI child forms better? If not, is there another solution?

[Solved] Hidden items showing empty space

I have a RadComboBox displaying 70 user options (yes, it's a lot, but it's needed to replicate an electronic device that has all of these settings). To simplify the option selection for users, I'm using a second RadComboBox to allow the user to see only subsets of the 70 options in the first RadComboBox. Whether I use the Hidden or Collapsed visibility settings for the items I wish to hide, an empty space is shown in the drop-down list so the list is just as long, but mostly empty. Is this the intended behavior of the RadComboBox, or have I set this up incorrectly? Please don't tell me I supposed to load separate collections of items and have different selected item event code for each subset.

Thanks in advance for your help.

Refresh hierarchical RadGridView data

I have setup a hierarchical RadGridView with a 2 command button columns on the master rows (remove, and add new child row), and the child rows have 1 command button, remove.. When adding a new child row, a modal form is shown and after the info is filled out and saved, the gridview was completely rebound and reloaded.. The same thing occurs when I hit a remove button, except that the row is deleted.. I originally had this working in the Q3 2007 version without any problems, but in upgrading to q1 2008, my same code no longer works..

I realize my original setup was probably less than correct, and i now have the gridview setup with 2 global BindingLists.. One is bound to the mastertemplate, and the other is bound to the childtemplate.. Now when I add a new child row, I just add the proper object to the child bindinglist variable, and it automaticaly shows up in the gridview (much better!)..

The problem I am having is that when I try to remove/delete a row [bindinglist.removeat(index)], I get the following error:

"This row has been removed from a table and does not have any data. BeginEdit() will allow creation of new data in this row."

I somewhat understand that the gridview is still bound to this object somehow.. What I don't understand is how to go about correcting the issue..

Any help would be appreciated, including any suggestions for how to accomplish refreshing the data on my gridview without the bindinglists

[Solved] Editing shipped themes and using them

I am building a VB.NET WinForms app and am using Telerik Controls for Winforms 2009 Q3. My users like the themes that ship with the controls with the exception of the fonts (which they want larger). My solution was to edit the themes (so they would be larger at design-time as opposed to updating them at runtime).

Here is what I did:

Download the source code
Update the font sizes (I just updated the font size of the Button, then changed the theme name to "TestAqua")
Compile the theme
Import the resulting dll into my app as a resource
Set its build type to be embedded
Build the app
Add a RadThemeManager to a form (for now, RadThemeManager1)
Add the theme to RadThemeManager1 (Change the location of the theme file, if needed)
Build the app again

Next I expected to do be able to set a RadButton's theme to TestAqua, but that theme was not available. Nor would it work by setting it in code. As I stepped through the code, I discovered that RadThemeManager1.InstalledThemeNames had a size of 1 (good), but that theme name was set to Nothing (that seems bad).

One of the reasons we got Telerik controls was that we thought this would be easy to do (and it still seems like it should be easy), so I'm hoping that I'm just not leaning in the right direction when I hit enter, or something. :-)

Thoughts?

PS If my original post shows up, sorry -- somehow it has not yet made it to the forum....

Context Sensitive help

Hi,

I am planning to have .chm file in my application.

A help icon on every tab to say what each tab stands for.

Do you have a suggestion as to how i can implement it. Is there a novel way to do in Telerik. I havent found any reading matter on it yet. Will i have to do it the old fashioned windows way?

Thanks in advance.,

Using different color blends for different forms

Is there any way to use a theme with a color blend on just some forms (or for example just the Rad message box) without affecting all the other forms that are using the same theme? In other words, do we have to create separate themes if we want the colors to vary for different forms?
