OK,

This does allow me to change the index of the field, but the property ActualPosition is still the one that seems to be used when displaying the fields.

In the end, all fields remain at their current position.

Guys,

I am experiencing this issue now.

Here is my scenario:

Launch UI

-Load Default Fields

-Allow user to customize visibility and position of the field via a field selector control

-Call SaveCustomizations and persist this info into data store.

Next time launching UI,

-Load Default Fields

-call LoadCustomizations to apply user settings

-And allow user to reconfigure the view (columns/positions)

With combination of this field selector GUI and user performing drag and drop action on the grid, I am experiencing different behavior when programatically move the columns around.

For me to understand this better,

A.

What is the value of ActualPosition.Column before user perform drag and drop?

Does the actual position gets changed after doing drag and drop?

Does the position of the dragged field get reset to original value when ClearCustomizations(CustomizationType.FieldPosition) gets called? If so it get reset to the position before calling LoadCustomization or position after calling LoadCustomizations?

B.

What is the expected value for Fields.Move oldIndex? Is that the current field index in Fields collection OR it is the Field.ActualPosition.Column OR it is Field.Column

C. What should I do if I want user to do drag and drop to move the columns around and/or use my field selector UI to perform the same.

I guess I need a solution that would work in both the cases where by I can move the columns programmatically irrespective of user performed drag and drop or not.

I would have to debug on this to understand it better, it would save my cycles if anyone had researched on this already.

Thanks for helping out.

Has anybody found a solution to this?

Hi All,

I have some problems while using SaveCustomization & LoadCustomization for XamdataGrid

Scenario:

-1. Dynamically adding Fields to the Grid on ViewerLoad event. Lets say the order is: Col1,Col2,Col3,Col4

-2. User add/removes Fields and do some ordering: Col3,Col2,Col1

-3. Saves the Layout of the Grid, using MemoryStream and SaveCustomization

-4. While loading it back the order which we get is: Col1,Col2,Col3 (see the order of the fields added initially)

Now when I checked the XML file, the order is as point no. 2. I wonder what is the issue here. 

Hello Ankit,

Could you please tell us what is the version of NetAdvnatage that you use, so we could be able to reproduce your behavior?

Looking forward for your reply.

Hello Ankit,

I can say that the firing of the events is normal, because our controls doesn’t fire them if the action is done by code. If so, you can execute the desired code after the action you perform. This is like a pattern for custom controls, which is used to have better performance.

Hope this helps you.

Stefan,

For throwing more light on the requirement, this will explain what I really want:

-The "FieldPositionChanged/Changing" event is fired only when user drag/drop columns in the grid.(As far as the documention in your website is concerned).

-I am hoping that is correct, in that case, I want to achieve all the column's position information even after I have changed the columns by some other means.

For Eg, I changed the collection and bind it accordingly to the grid. In this case, even if the ActualPosition would have changed for each column, but the FieldPositionChanged event would not fire, and thereby I would not get the details to save the layout, in which case, while loading the same layout, the column order would be intermittent.

-Can you suggest me some solution for the above wired scenario. I would be very grateful to you.

Thanks,

Ankit Srivastava 

Hi,

Now, All I want is a property which is fired whenever any fields in the dataGrid changes its position, so that I can fire the FieldPositionChangedEvent and get the XML file with field's position information.

Hi,

This works fine in the scenario where I an dragging and dropping the columns and then calling SaveCustomization().

But in between the two steps, I am adding one more step which is:

-Managing columns which shows the columns you want to add or remove, after doing that when I am hitting OK, in the back-ground I am clearing the customization with FieldPosition to accomodate the changes.

-And then I hit to SaveCustomization. I guess this is the reason why the XML doesn't gets the attribute's value for ActualPosition(ColSpan,RowSpan,Row,Column)

Is there a way in which we can save the customizations.

Hello Ankit,

Thank you for your post. I have been looking into it and I and I created a sample project for you following your scenario and everything seems to work ok on my side. If the sample doesn’t satisfies all your needs feel free to modify it, so it reproduces your behavior and send it back to me for further investigation. I tested the project both with the RTM and latest Service Release of version 11.1.

Looking forward for your reply.
