I found no issues when loading WebGrid with client-binding inside WebDialogBox. I set the content url of WebDialogBox to WebGrid's client-binding samples and found no issues with rendering on IE 11. All rows are loaded (not collapsed hidden).

Could you please provide me with more information about the problem so that I can assist you further?

• Does the grid renders correctly (all rows are not collapsed hidden) if not reside inside WebDialogBox?
• What kind of client-binding that used by your grid? (is it client-binding to: ADO data service; or client data source; or server data source; or WCF service; or Web service?)
• What are the settings of your grid's layout? (for example: Height; or Width; does AutoHeight or AutoWidth enabled?, etc.)

Look forward to hearing back from you.

Thank you for the hint. Instead of changing "UnitInStock" column as System.Decimal, I'm using "UnitPrice" column which by default has decimal data type.

The reported problem occurs if the following conditions are met:

• EditType of the column is NoEdit.
• DataFormatString of the column is set. For example: c2; or #,###,##; etc.

If your grid's structure met the above condition, the steps below can be used as workaround in order to avoid the problem.

1. Removes EditType="NoEdit" from the WebGridColumn definition.
   Original:
   <ISWebGrid:WebGridColumn ... Name="UnitPrice" DataFormatString="c2" EditType="NoEdit" ... />
   
   Modified to:
   <ISWebGrid:WebGridColumn ... Name="UnitPrice" DataFormatString="c2" ... />
2. In InitializeRow server-side event, enable ForceNoEdit of the cell. Enabling this property will force the cell to not allow editing (which has the same effect as set EditType to NoEdit).
   Example:
   protected void WebGrid1_InitializeRow(object sender, ISNet.WebUI.WebGrid.RowEventArgs e)
   {
       e.Row.Cells.GetNamedItem("UnitPrice").ForceNoEdit = true;
   }

I have tested this workaround and found that the exception is no longer persist when user paste multiple rows from clipboard. Please let me know whether this helps or not.

I tried to reproduce the reported problem in my local end by viewing BasicContextMenu.aspx sample file of WebDesktop in IE 11 browser but my efforts were not successful -- the menu (and its submenu(s)) is accessible and the mouse-over menu items works without any issues.

Could you please ensure the following in your IE 11 browser:

• Document mode is Edge (Default) and User agent string is Default.
• Compatibility view is disabled.

For your information, I'm using WebDesktop 4 build 14. Please let me know your response.

I tried to reproduce the problem by modifying SimpleLayout.aspx sample file of WebPaneManager. An unbound WebTreeView is added inside the ContentTemplate of "Side" WebPane.

<ISWebTreeView:WebTreeView ID="WebTreeView1" runat="server" Height="300px" Width="250px"
    ExpandedDepth="-1" RenderingMode="HTML5">
    <Nodes>
        <ISWebTreeView:WebTreeViewNode Name="WebTreeViewNode0" Text="Personal Folders"
            Expanded="True">
            <ISWebTreeView:WebTreeViewNode Name="DeletedItems" Text="Deleted Items">
            </ISWebTreeView:WebTreeViewNode>
            <ISWebTreeView:WebTreeViewNode Name="Drafts" Text="Drafts">

            <ISWebTreeView:WebTreeViewNode Name="JunkE-mail" Text="Junk E-mail">
            </ISWebTreeView:WebTreeViewNode>
            <ISWebTreeView:WebTreeViewNode Name="Outbox" Text="Outbox">
            </ISWebTreeView:WebTreeViewNode>
            <ISWebTreeView:WebTreeViewNode Name="RSSFeeds" Text="RSS Feeds">
            </ISWebTreeView:WebTreeViewNode>
            <ISWebTreeView:WebTreeViewNode Name="SentItems" Text="Sent Items">

                </ISWebTreeView:WebTreeViewNode>
                <ISWebTreeView:WebTreeViewNode Name="ForFollowUp" Text="For Follow Up">
                </ISWebTreeView:WebTreeViewNode>
                <ISWebTreeView:WebTreeViewNode Name="LargeMail" Text="Large Mail">
                </ISWebTreeView:WebTreeViewNode>
                <ISWebTreeView:WebTreeViewNode Name="UnreadMail" Text="Unread Mail">
                </ISWebTreeView:WebTreeViewNode>
            </ISWebTreeView:WebTreeViewNode>
        </ISWebTreeView:WebTreeViewNode>
        <ISWebTreeView:WebTreeViewNode Name="WebTreeViewNode1" Text="Archive Folder">
            <ISWebTreeView:WebTreeViewNode Name="DeletedItems2" Text="Deleted Items">
            </ISWebTreeView:WebTreeViewNode>
            <ISWebTreeView:WebTreeViewNode Name="SentItems" Text="Sent Items">
            </ISWebTreeView:WebTreeViewNode>
            <ISWebTreeView:WebTreeViewNode Name="SearchFolders2" Text="Search Folders">
            </ISWebTreeView:WebTreeViewNode>
        </ISWebTreeView:WebTreeViewNode>
    </Nodes>
    <NodeSettings EnableAnimation="True" />
</ISWebTreeView:WebTreeView>

To become more similar to your WebPane settings, the properties/attributes of "Side" pane is set to:

<ISWebDesktop:WebPane Name="Side" Text="Side" Width="Custom" WidthValue="15%"
    HeaderVisible="Yes" AllowCollapse="No" HeightValue="70%" Height="Custom" ContentScrollable="false">
    <ContentTemplate>
        <ISWebTreeView:WebTreeView ID="WebTreeView1" runat="server" Height="300px" Width="250px"
            ExpandedDepth="-1" RenderingMode="HTML5">
            ...
            <NodeSettings EnableAnimation="True" />
        </ISWebTreeView:WebTreeView>
    </ContentTemplate>
</ISWebDesktop:WebPane>

Save the changes and view the modified page in IE 11 browser. The reported problem doesn't persist. User can select node; WebTreeViewNode becomes underlined when user hovering mouse pointer over a node.

I enclose the modified sample for your reference. Please feel free to let me know if you find anything that I might miss during my attempt to reproduce the reported problem.

If you use Safari on Windows, you might want to consider switching to another browser. Since the release of Safari 6 on Mac, Apple has confirmed that it will not be released on Windows. Apple has also removed all Windows download link from its main Safari page, so Safari on Windows is probably a dead product.

For your information, I test the FirstExperience.aspx live sample of WebCombo on Safari 8.0.6 (running on MacOS) without any problems. Everything worked smoothly and the WebCombo was accessed without any issues.

Hope this helps.
