<Border BorderThickness="2" removed="BlanchedAlmond" >
<StackPanel Margin="30" Orientation="Horizontal">
<WrapPanel >
<Label Height="25" Content="Asset Component Description:" FontWeight="Bold" FontSize="12" Width="209"></Label>
<TextBox Height="26" Name="tbCompDesc1" TabIndex="1" Width="353" IsReadOnly="True" />
<TextBlock Text="
" Height="10"/>
<Label Content="Make and Model No.(Check if same for all)" Margin="50,0,0,0" FontWeight="Bold" FontSize="12"/>
<TextBox Height="26" Name="tbMkeMdl1" TabIndex="3" Width="259" Padding="0" MinLines="3" IsReadOnly="True" />
</WrapPanel>
<WrapPanel>
<Label Height="25" Width="209" Content="Component Qty for a Single Asset:" FontWeight="Bold" FontSize="12"></Label>
<TextBox Height="26" Name="tbCompQty1" TabIndex="3" Width="95" Padding="0" PreviewTextInput="numericTextboxKeyPress" MinLines="4" IsReadOnly="True" />

</WrapPanel>
<WrapPanel>
<Label Content="Depreciation Type:" FontWeight="Bold" Height="26" FontSize="12" Width="209" />
<ComboBox FontSize="16" Height="26" Name="cmbDeprtype1" Width="299" SelectionChanged="cmbDeprtype_SelectionChanged" TabIndex="6" IsReadOnly="True" />
<Label Height="25" Width="118" Content=" Depreciation Amt:" FontWeight="Bold" FontSize="12" Margin="50,0,0,0"></Label>

<DataGrid Name="dgCompDtl" AlternatingRowremoved="#FFE2BFD0" Height="494" Width="1115" AutoGenerateColumns="False" CanUserAddRows="False" CanUserResizeColumns="False" Loaded="dgDisplay_Loaded" FontSize="12" SelectionChanged="dgCompDtl_SelectionChanged">
<DataGrid.ItemContainerStyle>
<Style TargetType="{x:Type DataGridRow}">
<EventSetter Event="Mouse.MouseEnter" Handler="Show_PopupToolTip" />
<EventSetter Event="Mouse.MouseLeave" Handler="Hide_PopupToolTip"/>
</Style>
</DataGrid.ItemContainerStyle>
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Component_ID}" Width="50" Header="ID" >
<DataGridTextColumn.HeaderTemplate >
<DataTemplate>
<TextBlock Text="ID" TextWrapping="Wrap" FontWeight="Bold" FontSize="10"/>
</DataTemplate>
</DataGridTextColumn.HeaderTemplate>
</DataGridTextColumn>

Finally In the code behind I Have this two events Show_PopupToolTip and Hide_PopupToolTip
private void Show_PopupToolTip(object sender, MouseEventArgs e)
{
object item = dgCompDtl.SelectedItem;
CompID = (dgCompDtl.SelectedCells[2].Column.GetCellContent(item) as TextBlock).Text;
foreach (DataRow Dr in DTComp.Rows)
{
if (Dr["Component_ID"].ToString() == CompID)
{
/*This are the fields in the pop up which i am filling up from a DatatTable that has the detail data of the Data grid using the ID in the grid and matching it with ID in Table*/
tbCompDesc1.Text = Dr["Component_Desc"].ToString();
tbCompQty1.Text = Dr["Per_Asset_Qty"].ToString();
tbCompAmt1.Text = Dr["Amt"].ToString();
cmbDeprtype1.SelectedValue = Dr["DeprCalc"].ToString();
tbDRate1.Text = Dr["Rate"].ToString();
tbDAmt1.Text = Dr["DeprAmt"].ToString();
tbMkeMdl1.Text = Dr["Make_Model_No"].ToString();
// ..... etc
}
}
MyToolTip.Placement = PlacementMode.MousePoint;
MyToolTip.IsOpen = true;
}

1.One more thing for your information
CompID = (dgCompDtl.SelectedCells[2].Column.GetCellContent(item) as TextBlock).Text;
In your above line you are taking SelectedCells[2] for getting your CompID value which is actually at position no 1 as per your code in xaml so please replace it with

and try to run the program . Might now your content will get displayed
the code working for me is as follows
Please take one Latest WPF project and then try below things

during your code copy i came some error related to xaml like below
removed=\"BlanchedAlmond\"
AlternatingRowremoved=\"#FFE2BFD0\"
I had changed them respectively.
