  4. sfdatagrid with sfdatapager index must be within bounds of the list

sfdatagrid with sfdatapager index must be within bounds of the list

Support,

Environment: Syncfusion version 18.2.0.44 in Visual Studio 2019
I have an SfDataGrid control, along with an SfDataPager control with an observable collection bound to the pager. I can reproduce this every time in my current project. The following code exhibits the buggy behavior:

SfDataPager1.DataSource = logCollection;
SfDataGrid.DataSource = SfDataPager1.PagedSource;

The SfDataGrid has 2 columns of type GridTextColumn and both allow filtering. The first column is a date and time, while the second column is a message.

Now, when the form loads, I go and get data from a database, and store it in the logCollection observable collection. Over time, I will add new entries to via logCollection.Add().

So, when I filter the 2nd column (message) and then add a new item to the logCollection I get the following error:
Index must be within the bounds of the List. Parameter name: index

Also to note, when I add a new logCollection item, if the "message" is NOT the same as the text I'm filtering, no issues occur. The error above only exhibits itself when the new message added exactly matches that of the filtered text.

I can prevent this by not using the SfDataPager and by using the following code below instead of what I've indicated above:
SfDataGrid.DataSource = logCollection;

Data can be added to the collection and the new items appears in the filtered list without issue.

However, because this is a log, there will be thousands of lines, and I would like paging of that data for the user.
How can this be achieved?

Thanks.

I just noticed here in the documentation:
https://help.syncfusion.com/windowsforms/datagrid/paging#limitations-1

that:
  1. UI Filtering is not supported. You can code in application level to filter the data.
Can you confirm is this is still the case or if there is a workaround?

Thanks.

Based on provided information SfDataPager doesn’t support the UI Filter for Load Data in on-demand in SfDataGrid. We also regret to inform you that​​​ currently, Our SfDatagrid source architecture does not provide support to achieve your requirement of “UI Filtering support Load Data in on-demand in SfDataGrid”.
