Hi folks,

Is there any way to have the WinForms DropDownList control automatically drop down as soon as it has the focus?

Thx

Helen

Hello All

I desperately need your help on this most urgently.

Using VB.Net - Windows Form - VS2012

What I am trying to achieve on the attached screenshot2 - I want hide the following:

1. Groupbox 'Not' checkbox
2. Hide the dropdown list that shows 'Greater than' etc
3. Hide the dropdown list that shows 'less than' etc
4. Hide the radio buttons i.e. And, Or
5. Shift the two date picker controls to the center with labels [From] and [To]

So far I have managed to hide the Available Filter options to show only [Between] option - see screenshot1

Please, Please, can you provide a VB.Net coding on how to do this:

Private Sub rgvProblems_FilterPopupInitialized(sender As System.Object, e As Telerik.WinControls.UI.FilterPopupInitializedEventArgs) Handles rgvProblems.FilterPopupInitialized

If (e.Column.Name = "Raised")  Then

Dim filterPopup As RadDateFilterPopup = DirectCast(e.FilterPopup, RadDateFilterPopup)
Dim item As RadMenuItem = DirectCast(filterPopup.Items(1), RadMenuItem)

If (item IsNot Nothing) Then
'Only BETWEEN operator is visible
item.Items(0).Visibility = ElementVisibility.Collapsed
item.Items(1).Visibility = ElementVisibility.Collapsed
item.Items(2).Visibility = ElementVisibility.Collapsed
item.Items(3).Visibility = ElementVisibility.Collapsed
item.Items(4).Visibility = ElementVisibility.Collapsed
item.Items(5).Visibility = ElementVisibility.Collapsed
item.Items(6).Visibility = ElementVisibility.Collapsed
item.Items(7).Visibility = ElementVisibility.Collapsed
item.Items(9).Visibility = ElementVisibility.Collapsed

End If


Many thanks who can help me out on this.

Hi

Could you advise how to set the format for the text display element of a MultiColumn combo box?

The data member part of the drop-down is associated with a DateTime column for which I have set the FormatString property to {0:dd.MM.yyyy HH:mm} via the designer.

So, the drop down shows dates in my required format (e.g. 10.02.2015 12:00) but the text still displays as 10/02/2015 12:00:00.

Any help with customizing the format would be greatly appreciated.

Thanks

Adrian

I am converting a large project from some 2012 controls to the latest version.   All is going well, until I hit the treeview control.  

On compile, I get this error. 

Cannot implicitly convert type 'Telerik.WinControls.UI.RadTreeView.TreeViewEventHandler' to 'Telerik.WinControls.UI.TreeNodeCheckedEventHandler'

Not quite sure how to handle this. 

here is the referenced line of code
​ this.monitorRadTreeView.NodeCheckedChanged += new Telerik.WinControls.UI.RadTreeView.TreeViewEventHandler(this.monitorRadTreeView_NodeCheckedChanged);

I'm looking for a "best practices" guidance statement from Telerik regarding pros and cons of using WinForms versus WPF with regard to Telerik's future roadmap for continuing support and development of these control libraries.

Obviously, existing projects are most easily maintained in whichever format they were orginally designed and built. So the question here concerns selection of WinForms versus WPF for new projects only.

Starting a new project in WPF has the major advantage that it can be more easily converted to Silverlight. Are there any major advantages to starting a new project in WinForms? Are there any performance benefits for the WinForms Grid compared to the WPF Grid?

What are Telerik's "best practice" recommendations regarding these questions?

I'm trying to add a calculator to my project. I'm thinking that if I use a Rad Calculator DropDown with the popup opened inside an empty form it might work.

So far I have the form as you can see in the attached picture. I did hide the popup border using:

        Me.RadCalculatorDropDown1.CalculatorElement.CalculatorContentElement.DrawBorder = False


I did also hide the arrow button but I can't figure out how to hide the shadow.
My other problem is that when I click the textbox the popup calculator it goes away

It would be nice that you provide a full calculator control. 

Hi,
I'm  trying to use the dock functionality as MDI container, but has a problem when using autoscroll on child forms. So on resizing, scrolls are hidding or not showing correctly. I'm just wondering is there any specifity in use of autoscroll or there is some kind of problem that i'm seeing?

I have a Main form that is maximized by default.
I changed the inheritance of my Main form to now inherit from  RadForm.
Now when I open the Main form on my left monitor then the Main form has a small edge on the right that is bleeding into the left side of the right monitor.
See attachment for better explanation.

Hi,

How do I format a datetime column in a radgridview control?

I want to show ONLY the date part of the variable. 

I DID try removing it before entering it into the Grid, but then it just shows 12:00:00

I am guessing it has to do with DataEditFormatString or FormatString in the advanced settings for the column, but I've tried all kinds of strings with no luck.

Thanks
Johnny

My question is that is there any way i can get the property grid to reflect my changes that i make from another control. Right now it is working, but the only way i can see the change is when i set focus on the property grid. Is there any way i can force the property grid to update even when it has no focus, so that way as i can make changes to something is can see it been reflected in realtime in the property grid.
