Custom splitter control

[Beth Krawczuk]

Hi,
I'm trying to wrap the splitter control in a custom control.  Here's what I have so far, which doesn't error out but it doesn't paint a complete control.  It's seems to render the left "sliding zone" but not the insides.  Then it renders the right side correctly.

Any suggestions as to what I'm doing wrong?  Thanks, in advance, for your help.  You guys are always so helpful.

            // ----------- create the splitter control

            rightPane.Controls.Add(label1);

            mainSplitter.Items.Add(leftPane);
            mainSplitter.Items.Add(splitBar);
            mainSplitter.Items.Add(rightPane);

            Controls.Add(mainSplitter);
        }

Hello Beth,

I already answered your other thread - for your convenience I am placing my answer below:

The Controls collection is inherited from the Control class. The RadSplitter control is a complex control and its child controls are also third part user controls and according to some good practices it's comfortable to use another alternative collection for them. Considering the RadSlidingZone this collection is its Items collection. This being said, you should add the RadSlidingPanes in the Items collection as shown below:

   leftPaneSlidingZone.Items.Add(leftPaneSlidingPane);

   
We apologize for the inconvenience and we logged this in our TODO list - we will write additional code in order to make this controls available in the Controls collection too.

Your points were updated.



Best wishes,
