Hi,

    We have a issue after  Upgrading the Telerik dll Version(2012.2.724.40) (Web.UI,Web.Design,Web.UI.Skins) to Version(2013.3.1114.40)
in new version(2013.3.1114.40) Rad-grid header is not shown in IE.This working fine in FireFox and Chrome.

Sample html:



        <telerik:RadGrid    ID="radMailboxGrid" GridLines="Horizontal" OnItemDataBound="OnRadGridOnItemDataBound"
            runat="server" AutoGenerateColumns="false" Height="250px" Width="100%" EnableEmbeddedSkins="false"
            AllowSorting="True"  OnPreRender="OnRadGridOnPrerender" >
           
            <ClientSettings EnableRowHoverStyle="true" EnablePostBackOnRowClick="false">
                <Scrolling AllowScroll="True" UseStaticHeaders="true" SaveScrollPosition="true" />
                <Selecting AllowRowSelect="true" />
                <ClientEvents OnRowSelected="RowDblClick" />
                
            </ClientSettings>
            <HeaderStyle BackColor="#CCCCCC" />
            <MasterTableView AllowSorting="true" DataKeyNames="EmailID" TableLayout="Fixed" Width="100%"
                ItemStyle-CssClass="Hand">
                    <NoRecordsTemplate>
      <div>
        "No emails to display."</div>
    </NoRecordsTemplate>
                <Columns>
            
                    <telerik:GridTemplateColumn HeaderStyle-Width="2%" ItemStyle-Width="2%">
                        <ItemTemplate>
                            
                                <img runat="server" id="imgmail" style='border: 0px;padding-left:2px; ' />
                           
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn ItemStyle-Width="2%" HeaderStyle-Width="2%" SortExpression="EmailPriorityID"
                        HeaderImageUrl="/Images/candidate/layout/emailPriority.gif">
                        <ItemTemplate>
                            <img runat="server" id="imgPriority" style='border: 0px;' />
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn ItemStyle-Width="2%" HeaderStyle-Width="2%" SortExpression="HasAttachments"
                        HeaderImageUrl="/images/candidate/layout/Attachment.png">
                        <ItemTemplate>
                            <img runat="server" id="imgAttachment" style='border: 0px;' />
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridBoundColumn ItemStyle-Width="40%" HeaderStyle-Width="40%" SortExpression="EmailSubject"
                        HeaderText="Subject" DataField="EmailSubject">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn ItemStyle-Width="40%" HeaderStyle-Width="40%" SortExpression="EmailFrom"
                        HeaderText="From" DataField="EmailFrom">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn ItemStyle-Width="14%" HeaderStyle-Width="14%" SortExpression="ModifiedDisplayDate"
                        HeaderText="Received" DataField="ModifiedDisplayDate">
                    </telerik:GridBoundColumn>
                            <telerik:GridBoundColumn Display="false" DataField="EmailID">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn Display="false" DataField="IsCoach">
                    </telerik:GridBoundColumn>
                </Columns>
            </MasterTableView>
        </telerik:RadGrid>

Hello Matthew,

We are aware of such an issue but it happens only in Quirks mode. This mode is not supported by RadControls since it is based on IE5.5. Please check if this is not the case. Verify if the doctype is the firs directive in the rendered html and it is a valid one. Note that IE does not allow even comments before doctype. Also, you can download the latest internal build where this issue is fixed.

Hi Matthew,

The solution is to:

1. Download the latest internal-built where the issue is fixed

OR

2. Resolve the Quirks mode, i.e. set a valid doctype at the top of the page.

OR

3. Overwrite the _setupHeaderRotation method by adding this function at the bottom of the page:

JavaScript:

Telerik.Web.UI.GridTableView.prototype._setupHeaderRotations = function ()
{
    var that = this,
        columns = that.get_columns(),
        maxWidth = 0,
        cell;
    for (var i = 0; i < columns.length; i++)
    {
        cell = columns[i].get_element();
             
        if (Sys.UI.DomElement.containsCssClass(cell, "rgRotateHeader") && cell.children[0].offsetWidth > maxWidth)
        {
            maxWidth = cell.children[0].offsetWidth;
        }
    }
 
    if (parseInt($telerik.getComputedStyle(cell, "height", 0), 10) > maxWidth)
    {
        return;
    }
 
    if ($telerik.isOpera)
    {
        maxWidth += ["paddingTop", "paddingBottom", "borderTopWidth", "borderBottomWidth"]
            .reduce(function (memo, cssPropertyName)
            {
                var value = parseInt($telerik.getCurrentStyle(cell, cssPropertyName), 10);
                return memo + (isNaN(value) ? 0 : value);
            }, 0);
    }
 
    if (maxWidth != 0)
    {
        for (var i = 0; i < columns.length; i++)
        {
            if (columns[i].get_element().style.height == "")
            {
                columns[i].get_element().style.height = maxWidth + "px";
            }
        }
    }
}

These are all the possible solution, please choose the most suitable to your case, but note that if the browser is forced in Quirks mode it is developer's responsibility to maintain the quirks.

This is not a 'quirks' mode thing. It's a compatibility view issue.

If I may, I would like to suggest that your developers pay more attention to compatibility view issues before your product leaves the gate, since Microsoft pretty much forces all intranet sites to use compatibility view. Although you can turn this off, most companies in the US (not sure what other countries do) leave it on for intranet sites to keep the apps they've developed in-house looking the same.

Hi Charles,

As I've mentioned the issue (at least the one that Matthew described) is not related to Compatibility View mode of IE, since it cannot be replicated in any other scenario than Quirks Mode. If you are sure that your browser doesn't fall in Quirks mode and the issue is exactly the same like Matthew's issue I would suggest you to open support ticket and provide the following information at least:

1. The code relevant to the problem (even though it might not be runnable). In the best case I could provide a runnable sample project (it's always the best option).

2. Steps to reproduce (if any). E.g. "open the page --> you have to click this button --> a window will open --> the problem is observed

3. Screenshot if you believe it would be helpful (but in most cases it is).

Venelin
