Hi,

We guess there is a bug with "MinSize": (steps to reproduce)
Creat a project with two Docking Panels.
>>One small on the left side - the second filling the rest of the window.
Set MinSize on the left panel.
Make your window large.
Make the left panel as small as allowed in "MinSize".
Now make the Window smaller -- the left panel becomes smaller also.
>>Means MinSize does not work on window resizeing.

The other thing is with the panels background color of panels.
Steps to reproduce:
Again creat an app with two docking panels.
You will see that they change the BackColor to "ControlDark".
In properties use "Reset" to the BackColor -- it changes to "Control" (not bold).
Next run the app -- the panels have ControlDark as BackColor.
>> Check form1.designer.cs to ensure no backcolor is set.
Next close the form and reopen it in design view.
>>Code is added to set the BackColor to ControlDark.

We expect that BackColor work like it does with other Controls.
This means - Inheritance.
And this works well in designer!!

At the existing project change the BackColor of "PrimarySite" to Red.
Next choose "Reset" at the panels -- and YES they are red now - like they should.

Run the app -- again you have ControlDark panels - instead of red ones.

The second is easy to overcome by setting the color of the panel to a specific one.

The first is a real problem.

GridView ReadOnly / Alternating Color

Hi,

This is just a suggestion: setting GridView.MasterGridViewTemplate.AllowAddNewRow to false when selecting the gridview as readonly.

I cannot really imagine a situation where you would allow a user to insert a record but not be able to update it.

I only recommend this because I could not find the aforementioned property in the properties tab. It would be nice if this property was listed there but that's just me being nitpicky.

Lastly, could please describe how I can go about having a set color for every other row? I would like to have alternating colors for the rows similar to that of an ASP.NET GridView.

Thanks for the help,

Michael

Comparison of dates using datepicker

Hi,

I have two date pickers:
FROM and TO.

I'd like to know if the two dates are further than 3 days apart. How do I do this comparison? Is there a more efficient way than this?

var date = datePickerFrom.GetDate();
date.setDate(date.getDate() + 3);

var toDate = datePickerTo.GetDate();

if( toDate <= date )
.....

Thanks for your help.

readability when disabled

I'm working in an app that uses a "rowcard" format, when a row is selected there's a rowcard that is disabled that shows the details of the row. The GridView control is virtually impossible to read when it is disabled. Any suggestions for fixing this? The only thing I have so far is to not make the GridView's container disabled, but that's a pretty large and time consuming change. Most other windows controls are fine to read when they are disabled, but the GridView is not. Suggestions?

Problem error with PanelBar and Gallery Component combination.

i'm getting a weird error message when using your gallery component in combination with a panelbar groupelement that is set with EnableHostControlMode to true.

the project compiles and runs fine, but this error pops up however many times you have EnableHostControlMode set to true.

the error reads:
Error setting property "EnableHostControlMode" in class "Telerik.WinControls.UI.RadPanelBarGroupElement" to value "True".

it goes on to say that the element has already been added.

thanks guys...

06/06/07 - UPDATE
i was able to eliminate this error by toggling the said property to false, then toggle back to true through code.

why would there be such an issue with this, and a few other controls, to where the design time functionality acts flaky at times?

overall though, i'm liking the product thus far....

thanks.....

Multi column support, WHEN?

When Telerik win combobox will provide multiple column support? I did not see this feature in latest release. This is really important feature in our legacy system, and to me it's really basic. I have to decide soon how we want to landle it in new .net appication.

I see much more features in web controls than win and I am really disappointed at this stage. Any suggestions, alternates, or plan to provide this feature in next release?

Customize Ctrl+Tab feature

Hi all,

this is my question,
if I press Ctrl+Tab, I can browse through the opened documents/panels.
I can disable this feature by "dockingManager.UseQuickNavigator = false" property); I would like to assign this shortcut key (Ctrl+tab) to a custom function written by me, but I'm not able to catch this event (Ctrl+tab does not reach the keydown event).

How can I assign the Ctrl+tab shortcut to a function written by me?

Thanks in advance for the answer.
