I write this code in   objGrid_ColumnLayoutAssigned

// Code for Cell Template

StringBuilder CellETemp = new StringBuilder();

CellETemp.Append("<DataTemplate ");

CellETemp.Append("xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'");

CellETemp.Append("xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>");

CellETemp.Append(" <Grid x:Name=\"LayoutRoot\" Background=\"Transparent\" Width=\"119\">");

CellETemp.Append(" <Grid.ColumnDefinitions>" );

CellETemp.Append(

" <ColumnDefinition x:Name=\"ColValue\" Width=\"117\"></ColumnDefinition>");

CellETemp.Append(

" </Grid.ColumnDefinitions>");

CellETemp.Append(

" <TextBox x:Name=\"txtValue\" HorizontalAlignment=\"Center\" TextAlignment=\"Right\" Text=\"{Binding " + strHeader + " ,Mode=TwoWay}\" VerticalAlignment=\"Center\" Grid.Column=\"0\" Height=\"20\" Width=\"105\" Background=\"#FFF7F8F8\"></TextBox>");

CellETemp.Append(

" </Grid>");CellETemp.Append(" </DataTemplate>");

// Code For Header Template

StringBuilder HeaderTemp = new StringBuilder();

HeaderTemp.Append(

"<DataTemplate ");

HeaderTemp.Append(

"xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' ");

HeaderTemp.Append(

"xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' xmlns:tooltip='clr-namespace:Silverlight.Controls;assembly=ExtendedControls'> ");

HeaderTemp.Append(

" <StackPanel Orientation= \"Horizontal\">");

HeaderTemp.Append(

" <TextBlock x:Name=\"txtNormal\" Text=\"{Binding Converter={StaticResource HeaderConverter}, ConverterParameter='" + strPeriod + "'}\" HorizontalAlignment=\"Right\" />");

HeaderTemp.Append(

" <Image x:Name=\"imgNotes\" Source= \"../../images/notes.jpg \" Height=\"11\" Width=\"11\" >");

HeaderTemp.Append(

" <tooltip:ToolTipService.ToolTip>" +"<tooltip:ToolTip InitialDelay=\"0\" ShowDuration=\"30\">"+ "<TextBlock x:Name=\"txtNotes\" Text=\"TooltipTest\" Width=\"90\" FontSize=\"11\" FontFamily=\"Arial\" VerticalAlignment=\"Top\" TextAlignment=\"Left\"/>"+"</tooltip:ToolTip>"+"</tooltip:ToolTipService.ToolTip>");

HeaderTemp.Append(

" </Image>");

HeaderTemp.Append(

" </StackPanel>");

HeaderTemp.Append(

" </DataTemplate>"); 

e.ColumnLayout.Columns.Add(

new ColumnWidth(iWidth, false),IsSortable = false ,IsResizable =true,

HeaderTemplate = (

DataTemplate)XamlReader.Load(HeaderTemp.ToString()),

ItemTemplate = (

DataTemplate)XamlReader.Load(CellTemp.ToString()) });

this code working with Degault Style and i get ToolTip on headerColumn Image of XamGriD.

But If i apply style for Grid either at desinTime or Runtime the Tooltip is not seen

Please Reply...

Hi, 

The more information you can provide upfront the better. And if you have a sample that you can send, we can generally get to the bottom of a problem a lot quicker. 

I still need more information from you. Like what are you setting a style on. What style are you setting? What are you doing in the style etc...

Really if you could attach a sample that would be best. 

Thanks,

hi,

Thanks SteveZ

It just shouldn't have anything positioned over it. It doesn't have to be last. 

-SteveZ

So you mean ContentPresenter should be last at the ControlTemplate......

I believe it's b/c the mouse is being handled on the Dragger rectangle, which mean the tooltip is not getting notified that the mouse is over the contentPresenter. 

-SteveZ

Thank you Steve... Its Work.

But please can u explane me  what was the issue.Because i commented Dragger Rectangle then it was also worked.

I havent worked so much on style,ContentPresenter,ControlTemplate etc. so please explane . . .
