WebGrid crashes when scrolling with column freeze and setting a column hidden

Hi Eric,

I am sorry for the late reply. We have not released the official hotfixes. For now, you should use the nightly build hotfixes that I sent before. In next release the fixes should be included as well.

Hi Handy,

Sorry for the delay in testing this. I couldn't test the beta version on our production system and hoped that in the meantime a new stable version comes out. But as you moved to release 7, it looks like there are no more updates to version 6.

Yes, this hotfix seems to work for my sample. I just updated ISNet.WebUI.WebGrid.dll and ISNet.WebUI.WebGrid.Resources.dll from version 6.0.7200.218 to version 6.0.7200.220 and my sample doesn't crash anymore.

Let me know when the status of your control has made it from "nightly build hotfix" to a stable, tested version.

Thanks for your support.

Regards,

Eric

Hello Eric,

I am sorry for missunderstanding. Please ignore what I said before. I remembered that you are using WebGrid6. When submitted this bug, I input this into our WebGrid7 (due to our bug submission rules). It seems they forgot to fix in WebGrid 6 as well. I will notify them again.

Handy

??? Is this a typo?

Did you want to say that you thought that I was using WebGrid version 7? If your sentence was correct instead, then I don't understand what you wanted to say.

I mentioned the version in my initial mail.

So, I'll wait for more information then.

Hi Eric,

I thought you were using WebGrid 6. Perhaps, I will need to check it again in WebGrid 6.

FYI, You could not use WebGrid6 license for WebGrid 7.

Hi Handy,

Thanks for the update. But before testing this, I need some more infos. We just bought the update to version 6 a few months ago. Will this version 7 component work with our license for version 6?

If your build has not been regression tested (whatever this means in detail), then I prefer not to use it on our production system yet. But of course I can test it to give you feedback if it works now.

Thanks,

Eric

I experience that WebGrid crashes, when the user horizontally scrolls. This happens only when I set the first column to be frozen. It also only happens when I set some columns to hidden (Visible=false).

Attached is a simple sample in VB.NET for that (remove the .txt in the file names). Simplified, the sample contains:

An aspx file with the WebGrid "grdResult" and the columns "Description", "X1", "X2",..."X9"
<FreezePaneSettings AbsoluteScrolling="true" ActiveFrozenColumns="1" MaxFrozenColumns="1" ShowSplitterLine="False" />
In the aspx.vb code file there is a handler for InitializeDataSource which adds some static data to show, so that the grid is not empty
In the handler PreRender I change some column titles (from X1 to C1 etc.) and set two columns to Visible=False

When scrolling, it crashes with: "Microsoft JScript runtime error: 'parentElement' is null or not an object" (Break/Continue/Ignore). The debugger then stands on this JScript code: "var v1d119 =vfcb75.parentElement" (and vfcb75 is null).

I believe this is a bug in WebGrid. We are using the newest WebGrid 6.0.7200.218 and Framework 3.0.5000.705 and the users use Internet Explorer 6 to browse the page.

Can you confirm that this is a bug? If yes, will there be a hotfix available soon? Is there any workaround except not to use freezing or hiding?
