Hi Madhavan,

Unfortunately, I could not replicate your issue. I tried to create a simple sample based on your attached sample (not working because don't have your database) but my sample works fine. 
As far I know, you must not to use Multiple selection along with IsRowChecker feature.
This can cause conflic>>> Please read our WebGrid documentation about "Multiple Row Selection".
There should be an important note in there.
I don't know if your code worked in WebGrid 6, but I can say that you should not use both of that features together. 

Here a simple test.
Try to turn off AllowMultipleSelection and use IsRowChecker. You can still select multiple rows if you checked the checkbox.

Hi Handy,

Actually in our original code AllowMultipleSelection is not there.

In the replicated sample I was trying some thing and that;s why by mistake AllowMultipleSelection  tag was there.

Even with removing AllowMultipleSelection  tag and enabling rowchecker feature gives the same problem. 

Even with removing AllowMultipleSelection  tag and disabling rowchecker feature gives the same problem. 

Our product is working fine with this scenario in Webgrid 6.Only in Webgrid 7 we are facing this problem.Please advice.

Hi Madhavan,

     Just like my collague, I am having a problem to replicate the issue of yours. I have tried your scenario and everything works just fine. Perhaps,  we are missing something.

     Could you provide us with a running sample (using Northwind database) and replicate the issue? Thank you and have a nice day.

Best Regards,

Andi Santoso

Hi Andi,

Please find the attached sample with Northwind db.

This sample is for the scenario of

1.First do a grouping a column using Grouping by this field.

2.Then click on Enable check button.

3.It throws the Javascript error ( 'children.0.scrollWidth' is null or not an object) is thrown after enabling the checkbox.

Hello Madhavan,

Yes, I am able to replicate the issue. Actually, your scenario is not supported. As far I know, we could not toggle WebGrid Column via properties, Visible false/true with client side/html button. This needs FullPostBack.
I see that you were able to figured out how to trick this in WebGrid 6 but this is still not proper ways. However, the error is something we do not expect because we have not aware that because we could not hide WebGridColumn for now.

Hi Handy,

Any workaround for this without fullpostback.

Because same scenario is working fine in webgrid 6 in our product.

Our client will want the same feature if we migrate our product updates which is using webgrid 7.

We have to support this feature.

Please advice.

Hi Madhavan,
