I was able to reproduce the issue on my local end using Mozilla Firefox browser.

I have forwarded this issue to WebGrid development team to be investigated further. Should I hear any news regarding this issue, I will let you know.

The problematic behavior of WebGrid selected row on Mozilla Firefox browser has been submitted under work item #1058.

The issue is already queued in our work items. The hotfix of this issue is estimated to be available in the next build version of WebGrid 7. I will keep you updated with any news I heard from the team regarding work item #1058.

Hi,

can you already say when a new version of WebGrid 7 will be available? We want to publish our application soon and need the hotfix.

Christian

Unfortunately, the hotfix of work item #1058 is not available yet.

For your information, we can deselect row from client side by invoking ClearSelectedObject(true) method as shown in the following snippet code.

function DeselectRow()
{
    var WebGrid1 = ISGetObject("WebGrid1");
    WebGrid1.ClearSelectedObject(true);
    return true;
}

In my opinion, we can utilize this method to de-select row on the right event. Unfortunately, I haven’t found out the proper event of WebGrid. So far I have tried OnFocus and OnBeforeRowSelect WebGrid’s client side event with no luck.
