Thanks Mike,

The XML files I sent were copied immediately after the SaveAsXml method call. I created an empty temp file, called the SaveAsXml and then paused the program to get a snapshot of the xml file. Also, the temp file is created using a GUID so it's guaranteed to be unique.

I can try to create a sample, but the sample will not have the same level of complexity as the actual app. My thoughts are that it will work fine but I'll let you know.

Is there some other property I can test when the SaveAsXml call is made that could possibly show what's going on? I've already checked that the DataSource property is set, the DisplayLayout.Bands.Count is non-zero (1 in this case), and that the Bands.Items[0].Columns.Count is non zero.

Thanks,

Jim

So it seems like it's simply a question of referencing the grid control too early? I'm not sure I see how that could be the issue, though. Because you would have to set the DataSource and DataMember on the grid before you load the layout, anyway.So you would have had to reference the grid, anyway.

To further complicate matters, there is a known bug right now in v9.1 and up that sometimes causes the loading of the layout not to work correctly, so you might be running into that issue, as well. The issue will be fixed in the next service release.

If you want to try to duplicate the issue in a small sample project and post it here, I can run it with the latest internal build just to check and see if the issue is, in fact, fixed.

Hi Mike,

I also experience a bug in v9.1.

Rearranging, sorting etc does work.  But if I do a group-by a column then there is an error.

Example Data:

a,b,c
a,d,e
b,f,g

GroupBy First Column gives me two groups: group a and group b:

a,b,c
a,d,e
------- separator -----
b,f,g


However after a save and reload, I get three groups: group a, group a and group b, each with one item:

a,b,c
------- separator -----
a,d,e
------- separator -----
b,f,g

Is this the same bug as in v9.1.?  How I can track the content of the already reported bug and when it will be available?

Best regards,

Reto

Hi Reto,

It's impossible for me to guess if this is the same issue, but it sounds like it might be. The best thing for you to do is get the latest service release and see if it fixes the issue. I suspect it will.

If not, we can certainly look into it.

Hi Mike,

where can I get information about the latest service release?

Hi Mike,

thanks for the sample project. I finally found the reason for the behaviour.

I use DataBinding with a BindingList. Then on the UltraGridColumn, the GroupByMode was not set (therefore set to Default). This worked fine if I load the grid with the data and manipulate it, e.g. do grouping.  But when call SaveAsXml and LoadAsXml  (and no GroupByMode set), then the grouping does not work correctly anymore after LoadAsXml was called.  It may have do to something with the bound object types tough.

If I set the GroupByMode to Text, then it always works, so I am going to use that.

Hi Reto,

I just tested this out and it's working fine for me. I am attaching the sample project I used here so you can try it out.

Just run the sample, drag any column into the GroupByBox, then press the buttons in order from top top bottom to save, reset, and then re-load the layout.

Hi Mike,

I have installed the latest service release and it does not fix it. E.g. my version is:
Infragistics2.Win.UltraWinGrid.v9.1\9.1.20091.2039

If I have a grid, then group by  a column and do a SaveAsXML and immediately reload the output using LoadAsXML, the grouping is destroyed.

Can you please have a look at this?
