How do I use Self-Reference and Load On Demand but not an ISDataSource.
Posted: February 27, 2012 9:18 AM

I attempted to use classic paging, but the first two pages each take over 10 minutes to load. Unacceptable.

How do I use Self-Reference and Load On Demand but not an ISDataSource.

The sample works fine until I introduce Paging. I want to use it for a self-reference grid with about 3,000 parent rows. Each parent has between 0 and 100 children (and sub-children).

In LayoutSettings, after GridLineColor="236, 233, 216", enter the following:

PagingMode="VirtualLoad"
VirtualPageSize="4"
VirtualLoadMode="LargeData"

The attached images show the results of these changes.

The first image (SelfReference_NoCodeChange) shows before any code is changed.

The second image (SelfReference_CodeChange1) is when VirtualPageSize="4".

The third image (SelfReference_CodeChange2) is when VirtualPageSize="2".

Am I missing something, or is there a bug here?

I get the same issues (bad counts, not all data loading) when attempting to use page size 10 on 21 parent records with 0 to 34 child records.

 

 

 

Virtual Load Mode for LargeData

Arun,

Have you implemented your final solution for this problem?

I am attempting a similar build, but have been unsuccessful with my solution.

Any tips you could offer would be greatly appreciated.

WebGrid resize scrollbar height set to 2px

And in the image I posted on November 7, 2011, it clearly shows your obfuscated code performing a calculation on the scrollbarheight. The last section of that calculation adds 2 to the height. Clearly, there is a math problem in the code where the height is being calculated at less than 19px, and the code does not take that into account.

I understand about wanting to replicate the problem, but I do not have the time nor inclination to debug your code. A simple check of "if scrollbarheight < 19 then scrollbarheight = 19" would fix the problem.

 

 

Self-Ref Load On Demand with ISDatasource

Juliet,

I realize this post is over 2 years old, but I am attempting this same process - I have custom datasets built out of oracle that are my sources. Did you ever figure this out? Did Intersoft ever offer a solution for binding to a custom object?

 

Thanks.

Did this bug ever get resolved?

Hello, Eric. I hope this finds you well - and still checking these boards.

I am attempting to use an Oracle connection to load self-referencing data and cannot seem to get it just right. Where exactly did you find an examplue using - InitializeSelfReferenceDataSource - I am unable to locate a working example in the forums.

Thank you.

WebSplitter - where do I set the width to 10px?

Where can I find the "PaneSettings" properties documented?

You can't find the source code that sets the height? Is it possible for users to set the height? The source code should have the text "ScrollBarHeight", "offsetHeight", "clientHeight", and "+2".

"Perhaps, there is some conditions that force our script to resize the scollbar." - When would you set the scrollbar less than 19px (the default)?

The height should never end up being 2px - the scroller is near impossible to grab cleanly.

Have you identified the source code that makes this occur?

Will there be a fix coming?
