Hello,

Ok. I have notified this request to our developer teams. I will let you know after I got a response from them.
Actually, you don't need the combination server and client. If you used Dexter's workaround, it should work.

I need to perform this logic on the server side. My work around above works for me.

Can your report back when this issue is resolved? Thank you.

Hello,

AutoFitColumn can have a different result when set to true or false. When set it true, It will re-calculate all the columns width and resize the column proportionally.
That's why there is a different time. But I could not say it would affect to performance much. Based on my test in my project and your original project, I still could not replicate very slow performance related to AutoFitColumns.

I have solutions in this thread that show that the AutoFitColumns property affects performance dramatically. Please re-read some of the posts in this thread.  There were several performance issues and some how that AutoFitColumns property was altering performance. I am not sure if that was the culprit but it definately affected performance dramtically.

I think a change needs to be made to default the CSS in the WebGrid so that this sort of browser bug doesn't exist.  You cannot expect your user base to know that they need to specify some CSS to get around this issue.

I removed the child items to avoid this issue. I didn't find a work-around that fixed the performance issue. You should default the necessary CSS so that this issue doensn't occur.  One would never know to specify CSS or which CSS to avoid this issue.

Also, I don't understand the correlation between AutoFitColumn with the Grid and this issue but I have spent WAY too much time trying to figure it out. 

Hello,

For UI changes can be made on the server side only if the page is on FullPostBack mode. However, refresh is a FLyPostBack action. So, for UI changes, it is better if you do it in client.
But if you would like to do in server, try the following code.

protected void WebGrid1_InitializePostBack(object sender, ISNet.WebUI.WebGrid.PostbackEventArgs e)
    {
        if (e.Action == PostBackAction.RefreshData)
        {
            WebButton1.Enabled = false;
            WebGrid1.ClientAction.RenderControl(WebButton1);
        }
    }

Do you have a simple example? I am getting a JavaScript error using that approach.

I also tried the WebButton's RequiresUIRefresh method but it didn't work.

Hello,

AddStyle() would not be used if you customize all your style with CSS. WebToolBar/WebMenuBar provides properties which can be configured for its style. I already sent you the sample which I include all the style  in CSS and set it in those properties.

 <MenuStyleSettings BackgroundStripColor2="" MenuDropShadow="True" MenuAnimation="True"
  MenuWindowType="Normal" BackgroundStripColor="#E3EFFF">
 <CustomStyle CssClass="CustomStyle">
 </CustomStyle>
 <DisabledItemStyle>
 <Over CssClass="DisabledItemStyle-Over">
 </Over>
 <Normal CssClass="DisabledItemStyle-Normal">
 </Normal>
 </DisabledItemStyle>
 <CheckedItemStyle>
 <Over CssClass="CheckedItemStyle-Over">
 </Over>
 <Normal CssClass="CheckedItemStyle-Normal">
 </Normal>
 </CheckedItemStyle>
 <SeparatorStyle CssClass="SeparatorStyle"></SeparatorStyle>
 <FrameStyle CssClass="FrameStyle">

 <ItemStyle>
 <Over CssClass="ItemStyle-Over">

 <Normal CssClass="ItemStyle-Normal">

 <Normal CssClass="CommandStyle-Normal">

I will need to discuss with our developer about AutoFitColumn property. But after configure CSS, without AutoFitColumn, the performance works well.

Regards,

I went through the new CSS and made one-by-one changes to narrow down the CSS causing the problem. Our existing application had similiar CSS except some were CSS classes and other was CSS explicitly in the markup.  Oddly,  the missing css was the following that references an empty CSS class: <CustomStyle CssClass="CustomStyle"></CustomStyle>

This really makes no sense at all.  Please find out from the developers the following:

1) What CSS MUST be defined within the WebMenubar/WebToolbar to avoid this performance bug? I am looking for specific Style properties that must be specified and the valid CSS classes and/or style that can be used?

2) Why does the WebGrid's AutoFitColumn property fixes this performance bug?

3) Why does a Split/DropdOWn button within a WebMenubAR/WebToolbar control cause this performance bug? What is specific about this that causes the bug?

Thank you.

I also verified this is an issue with FIreFox and not just IE.
