Hello,

If you add a WebGrid Checkbox column, you will need to use IsRowChecker properties as true.
By clicking checkbox in the header column, you can select or unselect all.
Please see PreserveCheckedRows.aspx in our WebGrid sample.

I also would like to let you know the additional information regarding this link.
Currently, only WebGrid has this feature. 
You can see all features in our current R2 release by checking the release notes.
You can also see at http://support.intersoftpt.com and check at version history for each product.

Appearently, the your previous request has not been implemented yet.
As I ever told you at previous thread, you will need to add this as feature request in our developer network.

Regards,
Handy

If you are using our ISRowChecker for your checkbox, We have a clientside event called "OnCheckBoxClick". Hope you could use this event for your scenario.

Hi Henny,

Please open our WebGrid references and search "Walkthrough: Applying custom filtering in WebGrid"

It should guide you how to apply the custom filter.

Hi Yixin,

I am sorry. Based on your code, the timeout also is not working well. The reccurence of "i", got faster than newRow.Update. So, I would like to correct what I said before. You will still need to use TimeOut to delay for each process. But you must not to use recurrence when add "ID". Because, the time is not correct.

E.g
ID=AAAAA1,AAAAA2,AAAAA3. which (1,2,3) used "i" as repetition.
It is very hard to get the correct time out and mostly goes wrong. 

Therefore, when add multiple rows, you must not to use that repetition.
You will need to assign manually via button click.
e.g
ID=aaaaaa,bbbbbb,cccccc

However, adding multiple row at a once is not suggested because to get the exact delay time is very hard.

Hi Yixin,

You can hide it by set display none to its element.

e.g for the first Row

function Button2_onclick() 
{
    var grid = ISGetObject("WebGrid1");
    grid.RootTable.GetRow(0).GetElement().style.display = "none";  
}
