Radlistboxitem and label for

[blessed]

Is it doable?

i have a radlistboxitem list on which i would like to add label for, so that we will be able to select the checkbox using the label not the checkbox.

 

So far, i have this code, but it is not working. Your help will be greatly appreciated.

aspx

<telerik:RadListBox runat="server" ID="testRadlist" AutoPostBack="true" RenderMode="Lightweight" CheckBoxes="true" SelectionMode="Multiple" Width="215PX">
<ItemTemplate>
    <asp:Label runat="server" Text="Text" ID="lblRadlist" AssociatedControlID=""></asp:Label>
</ItemTemplate>
<Items>

</Items>

 

aspx.cs

testRadlist.Items.Clear();


        testRadlist.Items.Add(new RadListBoxItem {
            Value = "Summary",
           // Text = "Summary"
        });
        testRadlist.Items.Add(new RadListBoxItem
        {
            Value = "Edit",
            //Text = "Edit"
        });

        for (int i=0; i < testRadlist.Items.Count; i++)
        {
            testRadlist.Items[i].DataBind();
            Label lbl = (Label)testRadlist.Items[i].FindControl("lblRadlist");
            string val = lbl.Text;

        }
    }

Hello,

One option would be subscribing to the client-side click event of the Label and in the handler checking the belonging item.

• Is there a way to add an onclick event to an ASP.NET Label server control?;
• How do I pass a server control's actual client Id to a javascript function?;
• RadListBox Client-side object API (.findItemByValue() method);
• RadListBoxItem Client-side object API (.get_checked() and .set_checked() methods);

 

<script type="text/javascript">
    function checkItem(value) {
        var listbox = $find('<%= testRadlist.ClientID%>');
        var item = listbox.findItemByValue(value);
        item.set_checked(!item.get_checked());
    }
</script>

<telerik:RadListBox runat="server" ID="testRadlist"
    AutoPostBack="true"
    RenderMode="Lightweight"
    CheckBoxes="true"
    SelectionMode="Multiple"
    Width="215PX">
    <ItemTemplate>
        <asp:Label runat="server" Text="Text" ID="lblRadlist"></asp:Label>
    </ItemTemplate>
    <Items>
    </Items>
</telerik:RadListBox>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        testRadlist.Items.Clear();
        testRadlist.Items.Add(new RadListBoxItem
        {
            Value = "Summary",
            // Text = "Summary"
        });
        testRadlist.Items.Add(new RadListBoxItem
        {
            Value = "Edit",
            //Text = "Edit"
        });

        for (int i = 0; i < testRadlist.Items.Count; i++)
        {
            testRadlist.Items[i].DataBind();
            Label lbl = (Label)testRadlist.Items[i].FindControl("lblRadlist");
            lbl.Attributes.Add("onclick", "checkItem('"+ testRadlist.Items[i].Value + "');");
            string val = lbl.Text;
        }
    }
}
