In this post I will explain you how to create the CRM lookup control functionality in Silverlight data grid control. There will be a column of lookup data type that allows you to select related entity record as seen in bellow screenshot. Here in this example I am going to create a lookup column of an Account entity.
To implement the same look and feel of the lookup column, write the below given code in your xaml file of Silverlight application.
<sdk:DataGridTemplateColumn Width="190" Header ="Account" CellStyle="{StaticResource CRM2011_DataGridCellStyle}"> <sdk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Border BorderThickness="1">
<StackPanel>
<StackPanel.Resources>
<Style x:Key="LookupHyperlinkStyle" TargetType="HyperlinkButton">
<Setter Property="FontFamily" Value="Fonts/segoeui.ttf#Segoe UI"/>
<Setter Property="Foreground" Value="Blue"/>
<Setter Property="FontSize" Value="11"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="VerticalAlignment" Value="Bottom"/>
<Setter Property="FontWeight" Value="Normal"/>
<Setter Property="Padding" Value="3,0,0,2"/>
</Style>
</StackPanel.Resources>
<Grid x:Name="lookupData" Background="White">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="21"/>
</Grid.ColumnDefinitions>
<Image Source="{Binding Path=ink_AccountImageUrl}" Height="16" Width="16" Stretch="Fill" Grid.Column="0"></Image> <HyperlinkButton x:Name="LookupDataName" Grid.Column="1" Click="LookupDataName_Click" Style="{StaticResource LookupHyperlinkStyle}" > <HyperlinkButton.Content>
<Binding Mode="TwoWay" Path="ink_Account.Name"></Binding>
</HyperlinkButton.Content>
</HyperlinkButton>
<HyperlinkButton x:Name="OpenLookupData" Grid.Column="2" Click="OpenLookupData_Click" HorizontalAlignment="Right" >
<HyperlinkButton.Content>
<Image x:Name="ImgLookup" Source="/ExpenseNote;component/Images/LookupButton.png" MouseEnter="ImgLookup_MouseEnter" MouseLeave="ImgLookup_MouseLeave" Height="20" Width="21" Stretch="Fill"></Image>
</HyperlinkButton.Content>
</HyperlinkButton>
</Grid>
</StackPanel>
<Border.BorderBrush>
<LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
<GradientStop Color="Gray" Offset="0" />
<GradientStop Color="Gray" Offset="1" />
<GradientStop Color="Gray" Offset="0.105" />
</LinearGradientBrush>
</Border.BorderBrush>
</Border>
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
The column consists of mainly three controls:-
1) The image control to display account image. This is a web resource in Dynamics CRM.
2) The second control is a hyperlink button (in above example it is named as “LookupDataName”). Once you select a record from account lookup window, this link will help you to open the selected account record, same as we do in Dynamics CRM.
3) The third control is a hyperlink button (in above example it is named as “OpenLookupData”). This button will help you to open a popup window as shown in below screenshot.
Now let’s look into the code behind part of Silverlight control.
Below are the two methods that help you to toggle the images on mouse hover and mouse out for lookup hyperlink button (a third control).
private void ImgLookup_MouseLeave(object sender, MouseEventArgs e)
{ try
{ Uri uri = new Uri("/ExpenseNote;component/Images/LookupButton.png", UriKind.Relative); ImageSource imgSource = new BitmapImage(uri);
((Image)sender).Source = imgSource;
}
catch (Exception ex)
{ throw ex;
}
}
private void ImgLookup_MouseEnter(object sender, MouseEventArgs e)
{ try
{ Uri uri = new Uri("/ExpenseNote;component/Images/lookupbutton_hover.png", UriKind.Relative); ImageSource imgSource = new BitmapImage(uri);
((Image)sender).Source = imgSource;
}
catch (Exception ex)
{ throw ex;
}
}
Below is the method that will open lookup record window for an Account entity. Replace “_serverUrl” variable with your local variable. If you could see in below code, while opening lookupinfo.aspx page you are also allowed to specify other useful query string parameters like AllowFilterOff, DefaulType (Object Type), DidableQuickFind, DisableViewPicker etc. So, setup them based on your need.
/// <summary>
/// Opens account Lookup window
/// </summary>
private void OpenLookupData_Click(object sender, RoutedEventArgs e)
{ try
{ //Open Lookup for Account.
lookUpAccount = _serverUrl + "/_controls/lookup/lookupinfo.aspx?AllowFilterOff=1&DefaultType=1&DisableQuickFind=0&DisableViewPicker=0&LookupStyle=single&ShowNewButton=1&ShowPropButton=1&browse=0&objecttypes=1";
dynamic ReturnedParams = HtmlPage.Window.Invoke("showModalDialog", lookUpAccount, null, "dialogWidth:600px;dialogHeight:600px");
if (ReturnedParams == null)
{ return;
}
else
{ //Set the selected account
Guid AccountId = new Guid(ReturnedParams.items[0].id);
var AccountName = ReturnedParams.items[0].name;
TheMainViewModel.SelectedExpenseNote.ink_Account.Id = AccountId;
TheMainViewModel.SelectedExpenseNote.ink_Account.Name = AccountName;
TheMainViewModel.SelectedExpenseNote.ink_AccountImageUrl = "/ExpenseNote;component/Images/AccountImg.png";
}
}
catch (Exception ex)
{
throw ex;
}
}
If you notice I have implemented MVVM pattern in above code. The MainViewModel is an object of view model class. Its properties are bound with lookup controls. So, we just need setup the account Id, account name and image URL properties of this class. Now, once you select an account record from the popup window, the selected record will be displayed in a grid as shown in below screenshot.
Lastly, you wish to open that account record when you click on “test” hyperlink button as seen in below screenshot.
For that we need to write below code to open a main.aspx of Dynamics CRM in a popup window using “HtmlPage.PopupWindow” method.
private void LookupDataName_Click(object sender, RoutedEventArgs e)
{ try
{ if (((ink_expensenote)(ExpenseNotesGrid.SelectedItem)).ink_Account.Id != null)
{ Guid lookupId = new Guid(((ink_expensenote)(ExpenseNotesGrid.SelectedItem)).ink_Account.Id.ToString());
HyperlinkButton link = e.OriginalSource as HyperlinkButton;
if (link != null)
{ HtmlPopupWindowOptions options = new HtmlPopupWindowOptions();
options.Left = 0;
options.Top = 0;
options.Width = 800;
options.Height = 600;
options.Menubar = false;
options.Toolbar = false;
options.Location = false;
options.Resizeable = true;
options.Scrollbars = true;
//Open a record in new window
HtmlPage.PopupWindow(new Uri(_serverUrl + "/main.aspx?etc=1&extraqs=%3fetc%3d1%26id%3d%257b" + lookupId.ToString().ToUpper() + "%257d&pagetype=entityrecord"), "_blank", options);
}
}
}
catch (Exception ex)
{ throw ex;
}
}
I hope this post will be helpful to developers who want to have lookup type of column in Silverlight data grid control.
