Hi Clay, 

Again, there are several things wrong here.

The EditingControl property is set to "Value". That's fine. The editor will set the Value property of your control to the value of the cell when it goes into edit mode. But your value property setter does not do anything to update the UI. You are not updating the display.

Also, you are implementing INotifyPropertyChange, which is good. And your implementation only fires a notification when you click the OK button. That's fine, too. but you are firing the notification and passing in "ScheduleText". No such property exists on your UserControl, and even if it did, that's not the property that the editor is using - it's using Value, which is what you specified as the EditingControlPropertyName.

Hi Mike

Thank you -- the suggestions you made worked perfectly,  However, I'm still having a problem with this issue earlier in this post:

ClaySeifert:

When I click on the cell containing the usercontrol, the user control is populated correctly ONLY for the first row selected.  After that, no matter what row I click on, the data from the first row is what is passed to the usercontrol.  What am I missing that's preventing the current cells data from being used by the usercontrol?

 

When a cell enters edit mode, the UltraControlContainerEditor sets the Value of your EditingControl to the Value of the cell. So something must not be set up correctly in your control or the UltraControlContainerEditor. I'm afraid I can't guess what that is, but if you can post a small sample project demonstrating this behavior, I would be happy to take a look.

Maybe you need to specify the EditingControlPropertyName? Or maybe the control you are using is simply not responding the second time it's value is set?

Thanks and please advise.

Hi Clay,

I took a look at your sample and there are a couple of things wrong here that are preventing this from working correctly.

First off, your Schedule control, which you are using as the EditingControl has a MinimumSize applied to it.Not only does the control itself have a MinimumSize, but the instance of that control on the form has both a MinimumSize and a MaximumSize.

So the UltraControlContainerEditor cannot make the control any smaller to fit the cell.

If you remove all of that, it still won't work quite right, because the UltraDropDownButton inside your control is not set up to resize itself to the size of the control. The UltraControlContainerEditor cannot manipulate the controls inside your control. It doesn't know what control shows the text or how to arrange those controls, so you have to create a control that is resizable.

If you remove the MinimumSize and then set the UltraDropDownButton to Dock Fill so it fills the whole control, the sizing works fine.

You might want to try placing your UserControl on a form and docking or anchoring it to the form to test it's resizing behavior to make sure it works how you want it.

Regarding the clicking on the cell not working, the reason for this is that you have not set a RenderingControl. The UltraControlContainerEditor is expecting that you would not want clicks to apply to the editor unless the appearance of the cell is the same when in edit mode as when not in edit mode.

For example, suppose your EditingControl had 3 buttons on it and you did not specify a RenderingControl. When the user clicked the cell in that case, you would not want the button click to fire, because the user would not be able to see the buttons and he would not know which button he was clicking on.

Obviously, that kind of example does not apply in this case where you have a single control filling the whole area of the cell. So it looks like this is just a bad assumption in the code. I'm going to forward this thread over to Infragistics Developer Support so they can check it out and create a case for you.

In the mean time, you can get it to work very easily by adding a new Schedule control to the form and setting the RenderingControl property of the UltraControlContainerEditor to it. You might want to do this, anyway, since then you will see a dropdown arrow in the cell when it is not in edit mode.

Hi Mike

I've been able to resolve the last two (2) questions and it is reflected in the attached sample.  I've also implemented your suggestion for the first question but it didn't work.  I still have to click on the column two (2) times to expose the dropdown.  Regarding the second question, the attached sample will show what I'm experiencing.  As a side not, I was able to correct the inclusion of the dropdowm inside of the cell be setting the margins and paddings to 0.  However, the lenght of the dropdown still does not fill to the end of the cell area when the cell area is larger.

You'll have to make one change to the test application by placing the complete path to the sample data that's included in a .csv file.  This is marked by the string

<Change Path>\Scheduler\ScheduleData.csv

Thanks for your help
