I have a hierarchical menu of RadMenuItems

Item

   SubItem

       SubSubItem

If I select SubSubItem, is there any way via recursion I could iterate back up the tree to the top Item menu?

I saw a post from 2013 that suggested storing references to the preceding menu item in the Tag property but I'm wondering if there is a better way now to do this?

Thanks

1. if i set  MultiSelect = false;     

   after user click

   how can i get current row and it's data

 2. if i set  MultiSelect = true;     

   after user select many rows 

   how can i get these rows and it's data

I use a RadDropDownList, I want to give the user the ability to search the items in the drop down so I use the default DropDownStyle = DropDown with AutoCompleteMode = SuggestAppend.

However, I want to ensure that the user selects a valid item from the list and doesn't leave random text. So I created the extension method EnsureValidSelection() below that remembers the original value, and on validation resets it to that original value if no valid value is now selected.

This works well when the ValueMember is an int. But when it's a string, it ignores the code that sets the SelectedValue.

public static void EnsureValidSelection(this RadDropDownList combo)
{
    object originalValue = null;
    combo.Enter += DropDownEnter;
    combo.SelectedValueChanged += DropDownSelectedValueChanged;
    combo.Validated += DropDownValidated;
    return;

    void DropDownEnter(object sender, EventArgs e)
    {
        originalValue = ((RadDropDownList)sender).SelectedValue;
    }

    void DropDownSelectedValueChanged(object sender, EventArgs e)
    {
        if (originalValue != null && combo.SelectedValue != null)
            originalValue = combo.SelectedValue;
    }

    void DropDownValidated(object sender, EventArgs e)
    {
        if (combo.SelectedValue == null)
            combo.SelectedValue = originalValue;
        originalValue = null;
    }
}

Hi there, I have three panels and I want to hide the centre panel - how do I do this please?

I don't want to just make it zero width - I would like to hide it totally (including the sizing handle) until I need it.

Here is what I have tried thus far...

Me.mSplitContainer.SplitPanels("panFilter").SplitPanelElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed

Thank you in advance.

I've got a RadRibbonForm as my main form.  I'd like my users to be able to resize this form - and they can but the border is a single pixel making it nearly impossible to position your mouse over it in order to drag-and-resize.

I've tried creating my own Telerik.WinControls.UI.FormControlBehavior class called "CustomFormControlBehavior" that Inherits Telerik.WinControls.UI.FormControlBehavior with BorderWidth property that looks like this:

Public Overrides ReadOnly Property BorderWidth As Padding
Get
Return New Padding(10)
End Get
End Property

and in my main form's constructor, following InitializeComponent() I've added the following:

        Dim Behavior As Telerik.WinControls.UI.FormControlBehavior = New CARMSCustomRibbonFormBehavior()
        Me.FormBehavior = Behavior

The above code will not execute!

Can you help me resolve how to change the BorderWidth of my RadRibbonForm?  How close was I to the solution!? :)

Kindest regards, all!

I'm using the DockWindow on an MDI WinForms app. The Customer Search form is the first one to open.

When I open another form I'd like it to appear to the right of Customer Search. For some reason its appearing to the left.

The code below shows how I open it. Setting the MDIParent adds it to the DocumentWindows collection.

How can I get the Account form to appear to the right of Customer Search. (And any forms opened after that also must appear to the right.)

FormAccount? form = null;
foreach (HostWindow window in this.dock.DockWindows.DocumentWindows)
	if (window.MdiChild is FormAccount)
	{
		FormAccount formCandidate = (FormAccount)window.MdiChild;
		if (formCandidate.BranchId == GlobalServices.Instance.ActiveBranchID && formCandidate.AccountId == (accountId == null ? GlobalServices.Instance.ActiveAccount.NamesId : accountId))
			form = formCandidate;
	}

if (form == null)
{
	form = accountId == null ? new FormAccount(GlobalServices.Instance) : new FormAccount(GlobalServices.Instance, accountId);
	form.AccountId = GlobalServices.Instance.ActiveAccountID;
	form.MdiParent = this;
	form.SetImageAndTitle(ETitleFormat.Account);
	form.AccountFormType = EAccountFormType.Account;
	form.ControlBox = false;
	form.LaunchedFromIPC = launchedFromIPC;
	if (sender == null)
		this.WindowState = FormWindowState.Maximized;
	form.Show();
}

HostWindow hw = App.MainForm.dock.GetHostWindow(form);
if (hw != null)
	dock.ActivateWindow(hw);

Thanks

I may have missed someone already talking about this - but for those of us who like to give our users the ability to select their own "Theme" one ugly issue I'm constantly having to deal with is:  When the user changes their theme, I have to manually change the "look" for every Splitter in my application (400+ WinForm classes, there are probably a few thousand "Splitters")

Is there some technical reason there's no "RadSplitter" in the Telerik WinForms library and if there is not, I'd like to suggest that this be added.  It's a super-commonly used WinForm control, I'm a little shocked it's not already present in this spectacular WInForms UI Library!

p.s. using a SplitContainer is often not possible because of downward compatibility with the older app suits but does make a nice alternative for newer forms.

Kindest regards,

Hi there,

I would like to add controls to the navigation portion of the Navigation View if possible. I can place controls in front of the Navigation View (see attached image) but I was hoping to be able to add a panel above or below where the Navigation buttons are that will collapse if the Navigation VIew button section is collapsed. Is this at all possible or should I simply place controls in front of the Nav View as I have put in the image.

Thanking you in advance
