Problem while checking checkboxes in an unboundcheckboxfield
posted

I'm using v13.2 of the webdatagrid. My browser is IE11.

The grid has approx. 100 row and  20 columns.

My first column is an unboundcheckboxfield.

My problem:

When i use the 'Activation'-behaviour and i quickly check the checkboxes, it keeps unchecking some of the checkboxes.

It looks like the grid is executing a proces which isn't finished fast enough, so therefore all the checks that are done during the proces are not registered bij the grid.

When i remove the 'Activation'-behaviour the checking works perfect, but i need to be able to select a row and use the arrow-keys to browser the grid.

Please help. Thanks in advance.

    Hi Rob Kroot,

     

    Thank you for posting in our forums!

    Could you please let me know what are some of the other properties and behaviors you have set on your WebDataGrid?  Would you be able to provide your markup or a sample?  The unfinished process you see, is likely a postback.  Does it help if you set the BatchUpdating property of the EditingCore behavior to true if it is not already set?

    I followed the steps you suggested and was unable to reproduce the behavior you're describing.  I set a WebDataGrid with 100 rows and 20 columns with the first column being an UnboundCheckBoxField and activated CellEditing and Activation behaviors.  When I use the arrow keys and spacebar to rapidly check off columns, I do not see any instances where the checkboxes become unchecked.

    I have attached the sample project I used to test this.  Please test this project on your PC; whether or not it works correctly may help indicate the nature of this problem.

    If the project does not work correctly, this indicates either a problem possibly specific to your environment, or a difference in the DLL versions we are using.  My test was performed using IE11 with version 13.2.20132.2028 in Infragistics for ASP.NET 2013 Volume 2.

    If the project does show the product feature working correctly, this indicates a possible problem in the code of your application.  It will help if you can provide a small, isolated sample application that demonstrates the behavior you are seeing.

    Or, if this sample project is not an accurate demonstration of what you're trying to do, please feel free to modify it and send it back, or send a small sample project of your own if you have one.

    Please let me know if I can provide any further assistance.
