[Solved] identify the sender combo in the checkbox click event

[newbie]

I have a multi-select combo box using checkboxes.

I have this code in the click event of the checkbox to set the text of the combo:

function

stopPropagation(e)

 

{

e.cancelBubble =

true;

 

 

if (e.stopPropagation)

 

{

e.stopPropagation();

}

 

 

var combo = $find("<%= RadComboBoxType.ClientID %>");

 

 

var selectedItemsTexts = "";

 

 

var selectedItemsValues = "";

 

 

 

var items = combo.get_items();

 

 

for (var i = 0; i < items.get_count(); i++)

 

{

 

var item = items.getItem(i);

 

 

var checkbox = item.get_element().getElementsByTagName("input")[0];

 

 

if (checkbox.checked)

 

{

selectedItemsTexts += item.get_text() +

", ";

 

selectedItemsValues += item.get_value() +

", ";

 

}

}

 

selectedItemsTexts = selectedItemsTexts.substring(0, selectedItemsTexts.length - 2);

selectedItemsValues = selectedItemsValues.substring(0, selectedItemsValues.length - 2);

 

 

combo.set_text(selectedItemsTexts);

 

 

//Clear the selection that RadComboBox has made internally.

 

 

if (selectedItemsValues == "")

 

{

combo.clearSelection();

}

}

I have multiple multi-select combos on my page and therefore I want to identify the sender combo and set text in that combo accordingly, instead of hardcoding the RadComboBox name.

How can I do that?

Hello,

Here is how you can do this:

<telerik:RadComboBox ID="RadComboBox1" runat="server">
<ItemTemplate>
    <asp:CheckBox ID="CheckBox1" runat="server" onclick="updateCombo(this)" Text='<%# DataBinder.Eval(Container, "Text") %>' />
</ItemTemplate>
<Items>
    <telerik:RadComboBoxItem Text="item 1" />
    <telerik:RadComboBoxItem Text="item 2" />
    <telerik:RadComboBoxItem Text="item 3" />
</Items>
</telerik:RadComboBox>

<script type="text/javascript">
    function updateCombo(chk)
    {
        //example: chk.id = RadComboBox1_i1_CheckBox1
        var comboID = chk.id.replace(/_i(\d+)_CheckBox1$/, "");
        var combo = $find(comboID);
        combo.set_text("your text");
    }
</script>
