GridViewCustomSerialization exception on loading

[Gajan]

Hi,

When I try to load a persisted stream into a gridview, I receive the following exception:

[System.ArgumentOutOfRangeException] = {"Index was out of range. Must be
non-negative and less than the size of the collection.\r\nParameter name:
index"}<BR>

I am using the libraries of version 2012.1.215.40. I am following the GridViewCustomSerialization project in the demos as a guide.

The gridview has only two columns and its AutoGenerateColumns property set to false.

I would appreciate if you could indicate what could cause this exception as soon as possible.

Regards,
Gajan

[Gajan]

Has anyone got a solution on the above please?

Best Regards,
Gajan

Hi Gajan,

I prepared a sample solution to test your scenario but I couldn't reproduce the exception. Please have a look at the attached sample and let me know if it works for you or if I'm missing something.

Kind regards,

Hi Tina,

Thanks for the reply. I have solved the 'index out of range' exception by loading the stream in the loaded event of the control. I think I was loading it too soon which caused the exception.

However, I am still having issues with loading the GridView. On loading the stream, the columns got swapped and one of the headers is not displayed properly.

You can replicate this issue by copying the following code in the sample source you provided.

As you would notice, the girdview is part of a controltemplate defined in a style which is applied to a content control.

Hoping to hear from you soon.

Hello Gajan,

Thank you for sending the code snippets. I noticed that you're using a Label to define the Header of the  columns. However, the custom GridViewCustomPropertyProvider expects a string so you need to modify it to persist the content of the label. For example you can change the ColumnProxy class Header property to be of type object. And you can to take the header of the columns as a Label or a ContentControl and change the ProvideValue/RestoreValue methods to take the content of the Label/ContentControl.

Also the columns cannot be properly differentiated as they don't have a UniqueName property set. Please set this property as it is used by the GridViewCustomPropertyProvider to distinguish the columns.

I modified my solution accordingly. Give it a try and let me know if it helps.

All the best,

Hi Tina,

Thank you for your advise and it solved the problem to a certain extent. 

I have set the UniqueName property for each column. I have removed Header property from ColumnProxy class as I am binding the header value and do not want to persist and load.

This works, however, after a few iterations of saving and loading, the value for 'proxy.DisplayOrder' of all columns are somehow set to -1 when saving and causes exception on loading the next time (at the following line in RestoreValue method). 

column.DisplayIndex = proxy.DisplayOrder;

I cannot find any pattern on when this happens (DisplayOrder getting set to -1) and it appears random. 

Hope to hearing from you soon.

Best Regards,
Gajan

Hello Gejan,

Usually the DisplayIndex of all columns that aren't fully initialized is -1. And if in your application at a certain point you're saving the column settings of a grid that isn't fully initialized or it's not initialized at all, such an issue may arise.

However as I am not sure how you've implemented your scenario and how you go through the save/load iterations, I am not sure if this is indeed the reason for the issue. But if you can send us a sample solution reproducing it, we will be able to further investigate the cause.

Kind regards,

Hi Tina,

I am also getting the same problem (DisplayIndex for all columns is assigned to -1). Could you please help me to resolve the problem.

Note: In one view it is working fine(returning proper DisplayIndex for each column) but some other view its returning -1.

Thanks
Raj

[Tina Stancheva]

Hi Raj,

In the views where the DisplayIndex is -1, perhaps the PersistenceFramework Save logic is implemented too early - while the RadGridView hasn't fully loaded and initialized its columns. If you can send over a sample solution demonstrating your approach and the issue, we will be able to suggest how to modify the persistence logic to make sure the RadGridView settings are properly saved.

Hi Tina,

Thanks for your reply.

Since i am getting the below error message, i am not able to upload the solution zip file. Evenafter changed the extension to .png.
i have upload the screenshot of my usercontrol codebehind.

Reply to thread cannot be created because:

• Please upload valid files: .jpg,.jpeg,.gif,.png smaller than 2MB.

I am able to store and restore the settings using button events. but i need this task to be done on load and unload events.
I have tried to load the settings on usercontrol loaded event and gridview loaded event both failed. 

Note: I would like to load the settings from IsolatedStorage on loading the view and save the changes on leaving the view. 

Thanks
Raj

Hi Raj,

The forums only allow small image attachments and this is why we encourage our customers to use the support ticketing system when they need to describe a specific case and attach their scenario implementation.

However, the snapshot you sent helped me better understand your case and the issue is really caused by the fact that you're trying to load the RadGridView persisted settings too early. When the control is loaded, the RadGridView isn't yet fully initialized and its columns aren't yet generated completely and their DisplayIndex is still -1. This is why it's best to call the LoadState() method using a Dispatcher in the RadGridView.Loaded event handler. This why you'll be sure that the control is fully loaded and ready to get its restored settings.

From the snapshot you sent, it seems to me that your application is targeting Silverlight and this is why I attached a sample solution demonstrating how to load the RadGridView settings when the application has loaded and how to save the state of the control, when you exit the application. Even if you're targeting WPF, you can still use the same approach.
