Strange resize issue with complicated layout

I have a fairly complicated window layout, and it seems like at some point the resize events from a user resizing the form stop propagating after a while. In my form I have a RadDock that contains a Document window that contains a PageLayout Control that contains a SplitterWindow That contains a RadDock.

Inside the rad dock I have 3 ToolWindows that get resized correctly but I have controls that are dockFilled in these windows these controls are not resized. So this leads to a bunch of redraw errors and makes the screen look very bad.

I tried a bunch of ways to simplify the layout but each one I tried worked correctly.
In my sample Application I have Form, main form with the RadDock and DocumentWindows, UITabControl (the RadPageLayout), ReportViewer (the SplitContainer), and EmptySnapshotControls which has the second RadDock which has the resize errors. On the resize event of the ToolWindows I'm displaying the size of the ToolWindow and also the control that is inside the ToolWindow, so you can tell sometimes the second set of numbers don't change. (when there is more that 1 control side by side)

In my sample app the first view shows the error and I have a few other tabs where I've tried to simplify the layout and they work correctly. If I take out the splitContainer or remove the PageLayoutControl works fine. (As you can see in my sample)

Anyway if you can figure out whats going on or can find a workaround I'd be very grateful.

I couldn't attach a zip file to attach my post so I'll try to email it to you. Let me know if there is a better way for me to do this.

Thanks

A problem applying custom theme to a disabled RadDropDownList (Thread vanished)

Hello again,

**** THIS IS A RESPONSE TO A PREVIOUSLY CREATED THREAD ****

Apparently the thread vanished...

Anyway you could always create a custom control, something like this, so you could pass all the extra logic there, including but not limited to themes and other info..

public class CustomDropDownList : UserControl

{

private RadDropDownList dropDownList;

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]

public RadDropDownList DropDownList

{

get

{

return dropDownList;

}

public CustomDropDownList()

{

dropDownList = new RadDropDownList();

dropDownList.Dock = DockStyle.Fill;

this.Controls.Add(dropDownList);

this.Size = new Size(dropDownList.PreferredSize.Width, dropDownList.PreferredSize.Height + 1);

}

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

if (!dropDownList.Enabled || !this.Enabled)

{

this.Enabled = true;

dropDownList.Enabled = true;

dropDownList.Enabled = false;

this.Enabled = false;

}

protected override void Dispose(bool disposing)

{

base.Dispose(disposing);

if (dropDownList != null)

{

dropDownList.Dispose();

dropDownList = null;

}

(The screenshots below are for the thread disappearance itself)

Hope this helps, if you have any other questions or comments, please let me know,

Best Regards,

Properties Window not working

I recently installed the Q1 build and now my Properties window does not seem to be working.

If I click on one of the ribbonbar controls either in the designer or in the Document Outline window, the control is NOT selected in the Properties window. In order to access a control in the Properties Window, I need to pick it from the drop down list in the Properties Window.

Add this to on/off problems in selecting any ribbon bar controls in the designer and this has gotten to be almost unusable at design time.

Do I possibly have something set/installed wrong that is causing these problems?

Thanks for any help.

Display Truncated On Load

I'm using the MultiColumnComboBox control. When the .DataSource is set and the items are bound to this control initially, the currently selected item does not display correctly in the UI. The text is partially truncated (on the left). Please see screenshot which demonstrates this.

[Solved] PageView with child controls like PanelBar

Hi,

I've gone through the examples for the Pageview control and how to migrate some things from the PanelBar control. The one thing I don't see is an equivalent version of the RadToggleButtonElement for the subitems in the Pageview group.

Thanks,
