how can I create a ItemTemplate on server-side?
I tryed to add it in the OnInit method like this:
public
class FilterPanel : FilterPanelBase {
protected override void OnInit(EventArgs e)
{
FilterPanelTemplate t = new FilterPanelTemplate();
Control myContainer = new Control();
t.InstantiateIn(myContainer);
this.ItemTemplate = t;
base.OnInit(e);
}
}
public
class FilterPanelTemplate : ITemplate
{
public void InstantiateIn(Control container)
{
TextBox _filterInput = new TextBox();
_filterInput.ID =
"_filterInput";
_filterInput.Text =
"Suchbegriff...";
container.Controls.Add(_filterInput);
}
}
It doesn't work.
Thanks for help.

so now I get the added controls, but the controls are shown under the first level. How can I add controls to the first item level(shown in the same line with the collaps-icon)? I tryed to use a div control, too. But it doesnt work.
thanks for support
Please refer to our Templates example for details on the matter.

hello,
I know the example. And if I add my dyn. created controls like this: planitem1.items[0].controls.add(xxx). The controls will be added. But not in the first level row.
On code-behinde: added controls are created into the div for template items.....So how can I display the added controls in the same line like the collaps-button.
thanks
Please find below a sample code snippet that shows the needed approach.
ASPX:
| <html xmlns="http://www.w3.org/1999/xhtml"> |
| <head runat="server"> |
| <title>Untitled Page</title> |
| <style type="text/css"> |
| div.RadPanelBar .rpItem |
| { |
| position: relative; |
| } |
| div.RadPanelBar .rpTemplate |
| { |
| position: absolute; top: 2px; right: 0; |
| } |
| </style> |
| </head> |
| <body> |
| <form id="form1" runat="server"> |
| <asp:ScriptManager ID="ScriptManager1" runat="server" /> |
| <asp:Button ID="Button1" runat="server" Text="Button" /> |
| </form> |
| </body> |
| </html> |
Code-behind:
| protected void Page_Load(object sender, EventArgs e) |
| { |
| RadPanelBar panelbar = new RadPanelBar(); |
| panelbar.ID = "RadPanelBar1"; |
| panelbar.Width = Unit.Pixel(300); |
| form1.Controls.Add(panelbar); |
| if (!IsPostBack) |
| { |
| RadPanelItem panel1 = new RadPanelItem("root1"); |
| panelbar.Items.Add(panel1); |
| RadPanelItem Child1 = new RadPanelItem("Child1"); |
| panel1.Items.Add(Child1); |
| RadPanelItem Child2 = new RadPanelItem("Child2"); |
| panel1.Items.Add(Child2); |
| } |
| TextBox tb = new TextBox(); |
| tb.Text = "test"; |
| tb.CssClass = "test"; |
| panelbar.Items[0].Controls.Add(tb); |
| } |
