There are several ways you can set the content inside a RadDock control:
Creating a ContentTemplate at design time
You can add controls to the ContentTemplate property and RadDock will automatically display them runtime.
| [ASP.NET] ContentTemplate |
 Copy Code |
|
<telerik:RadDock runat="server" id="RadDock3" Title="ContentTemplate">
<ContentTemplate>
<div style="margin:10px;">
<asp:Label runat="server" id="Label1">You can put text and controls in the ContentTemplate.</asp:Label>
</div>
<div style="margin:10px;">
<asp:Calendar runat="server" id="Calendar1"
/>
</div>
</ContentTemplate>
</telerik:RadDock>
|
You can access the controls in the ContentTemplate at runtime to get or set their properties:
| [C#] Accessing controls in the template |
Copy Code |
|
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Calendar1.SelectedDate = DateTime.Today;
}
}
|
| [VB] Accessing controls in the template |
Copy Code |
|
Protected Sub Page_Load(ByVal sender As
Object, ByVal e As EventArgs) Handles
Me.Load
If Not Page.IsPostBack Then
Calendar1.SelectedDate = DateTime.Today
End If
End Sub
|
Assigning the ContentTemplate at runtime
You can create a class which implements the ITemplate interface and set its instance to the ContentTemplate property from the code-behind:
| [C#] Assigning ContentTemplate at runtime |
Copy Code |
|
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
RadDock1.ContentTemplate = new CalendarTemplate();
}
}
class CalendarTemplate : ITemplate
{
public void InstantiateIn(Control container)
{
Calendar calendar1 = new Calendar();
calendar1.ID = "Calendar1";
calendar1.SelectedDate = DateTime.Today;
container.Controls.Add(calendar1);
}
}
|
| [VB] Assigning ContentTemplate at runtime |
Copy Code |
|
Protected Sub Page_Load(ByVal sender As
Object, ByVal e As EventArgs) Handles
Me.Load
If Not Page.IsPostBack Then
RadDock1.ContentTemplate = New CalendarTemplate
End If
End Sub
Class CalendarTemplate
Implements ITemplate
Public Sub InstantiateIn(ByVal container As Control)
Dim calendar1 As New Calendar()
calendar1.ID = "Calendar1"
calendar1.SelectedDate = DateTime.Today
container.Controls.Add(calendar1)
End Sub
End Class
|
Adding controls directly to the content container
Instead of creating a class which implements ITemplate, you can directly add controls to the ContentContainer.Controls collection. This is slightly easier to
implement, but you cannot easily reuse the template in other controls.
| [C#] Adding controls to ContentContainer |
Copy Code |
|
protected void Page_Load(object sender, EventArgs e)
{
Calendar calendar1 = new Calendar();
calendar1.ID = "Calendar1";
RadDock1.ContentContainer.Controls.Add(calendar1);
}
|
| [VB] Adding controls to ContentContainer |
Copy Code |
|
Protected Sub Page_Load(ByVal sender As
Object, ByVal e As EventArgs) Handles
Me.Load
Dim calendar1 As New Calendar()
calendar1.ID = "Calendar1"
RadDock1.ContentContainer.Controls.Add(calendar1)
End Sub
|
 |
Note that when using the ContentContainer property, you should always execute the code, even on a
postback. This is because controls you add this way are not persisted in the ViewState. |
Setting the Text property
If the RadDock control only needs to display plain text, you can use the Text property.
| [ASP.NET] Using the Text property |
Copy Code |
|
<telerik:RadDock
ID="RadDock1"
runat="server"
Text="This text appears in the content area of the RadDock control when
there is no template." >
</telerik:RadDock>
|
