Hello,

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.

Hello,

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

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

Hi Rahel,

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);  


Kind regards,
