    string MACAddress = "";

    foreach (ManagementObject mo in moc)

    {                

        if (mo["MacAddress"] != null)

        {                    

            MACAddress = mo["MacAddress"].ToString();

            MessageBox.Show(MACAddress);

Create "hhhh.bmp" Code:

( Add " Neodynamic.WPF.Barcode.dll" in refarence)

private void UpdateBarcodeOnHeader()

                    return;
                }

                barcodeimage.SetValue(System.Windows.Controls.Image.SourceProperty, null);
                //Create an instance of Barcode Professional
                BarcodeProfessional bcp = new BarcodeProfessional();

Autosuggest Textbox for WPF

In this post i will share to everyone how to make an auto suggest TextBox in wpf like GOOGLE Textbox.
For this i create a grid whose first row contains a textbox and the second row contains a Listbox. Now, when the textbox gets the focus and its text changes due to the user’s input then fill up the listbox.
Here is the XAML code

1

<Grid>

2	<TextBox Height="23" HorizontalAlignment="Left" Margin="111,46,0,0" Name="txtAutoSuggestName" VerticalAlignment="Top" Width="161" PreviewKeyDown="txtAutoSuggestName_PreviewKeyDown" TextChanged="txtAutoSuggestName_TextChanged" />

3	<ListBox Height="Auto" HorizontalAlignment="Left" Margin="111,69,0,0" Name="listBoxSuggestion" VerticalAlignment="Top" Width="161" Visibility="Hidden" PreviewKeyDown="listBoxSuggestion_PreviewKeyDown" KeyDown="listBoxSuggestion_KeyDown" />

4

</Grid>

Now this is CS code for glorious effect in textbox

view sourceprint?

01	private void txtAutoSuggestName_TextChanged(object sender, TextChangedEventArgs e)

02

{

03	listBoxSuggestion.Items.Clear();

04	if (txtAutoSuggestName.Text != "")

05

{

06	List<Customer> namelist = CustomerGatewayObj.listShow(txtAutoSuggestName.Text);

07	if (namelist.Count > 0)

08

{

09	listBoxSuggestion.Visibility = Visibility.Visible;

10	foreach (var obj in namelist)

11

{

12	listBoxSuggestion.Items.Add(obj.id);

13

}

14

}

15

}

16

else

17

{

18	listBoxSuggestion.Visibility = Visibility.Hidden;

19

}

20

}

21

22	private void txtAutoSuggestName_PreviewKeyDown(object sender, KeyEventArgs e)

23

{

24	if (e.Key == Key.Down)

25

{

26	listBoxSuggestion.Focus();

27

}

28

}

29

30

31	private void listBoxSuggestion_PreviewKeyDown(object sender, KeyEventArgs e)

32

{

33	if (listBoxSuggestion.SelectedIndex == 0 && e.Key == Key.Up)

34

{

35	txtAutoSuggestName.Focus();

36

}

37

}

38

39	private void listBoxSuggestion_KeyDown(object sender, KeyEventArgs e)

40

{

41	if (listBoxSuggestion.SelectedIndex > -1)

42

{

43	if (e.Key == Key.Enter)

44

{

45	txtAutoSuggestName.Text = listBoxSuggestion.SelectedItem.ToString();

46

}

47

}

}

Multi Column ComboBox in C# WPF

For my working purpose I wanna try to make a multiple column Combox Box.So i prepare myself to make this.But i fetched too many problem for this and Finally i have gotten this solution.
At first write this code in XAML file to create MultiColumn ComboBox.

<ComboBox Grid.Column="1" Height="23" HorizontalAlignment="Left" Margin="1,0,0,232" Name="cmbWHTypeId" Width="175" TabIndex="0" VerticalAlignment="Bottom">

<ComboBox.ItemTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding WhtID}" Width="60"/>

<TextBlock Text="|" Width="10"/>

<TextBlock Text="{Binding WhtName}" Width="100" />

</StackPanel>

</DataTemplate>

</ComboBox.ItemTemplate>

</ComboBox> Then Write the following Code in CS file of  UI cmbWHTypeId.ItemsSource = objBWhTypes.GetAllWhTypes(); Here GetAllWhTypes() is a method which returns a list collection. view sourceprint? public List<EWareHouseTypes>GetAllWhTypes() { List<EWareHouseTypes> liWhTypes = new List<EWareHouseTypes>(); try { IEBSDataContext objDataContext = new IEBSDataContext(); var b = from WAREHOUSE_TYPES in objDataContext.SP_WarehouseType_GetAll() select WAREHOUSE_TYPES; foreach (var item in b) { EWareHouseTypes objEWhTypes = new EWareHouseTypes(); objEWhTypes.WhtID = item.WT_ID; objEWhTypes.WhtName = item.WT_NAME; liWhTypes.Add(objEWhTypes); } } catch (Exception e) { throw e; } return liWhTypes; } EWareHouseTypes is a class and it contains two property id and name.

GET VALUE FROM COMBO BOX EWareHouseTypes aWHType = (EWareHouseTypes)cmbWHTypeId.SelectedItem; MessageBox.Show(aWHType.WhtID); Manually SET INDEX for a Particular ID string typeID="WHT01" for (int i = 0; i < cmbWHTypeId.Items.Count; i++) { EWareHouseTypes aWHType = (EWareHouseTypes)cmbWHTypeId.Items[i]; if (aWHType.WhtID == typeID) { cmbWHTypeId.SelectedIndex = i; break; } } If you have any query about this topic please leave a comment.
