Using multiple columns for DataTextField

[bill]

Is there a way to specify multiple data text field columns?  It would also be nice to beable to use the format string.  Some thing like this:

DataTextField

 

="ratecode;description" DataTextFormatString="{0} - {1}" DataValueField="rateid"

Hello,


You can easily achieve this by using following code in ItemDataBound event.

C#:

protected void RadComboBox1_ItemDataBound(object sender, RadComboBoxItemEventArgs e)
{
    DataRowView dataSourceRow = (DataRowView)e.Item.DataItem;
    e.Item.Text = e.Item.Text + " - " + dataSourceRow["description"].ToString();
}

This does not work with client-binding though.  Is this going to be supported in the future?

Hello Patrice,

You can use attributes to achieve this functionality when RadComboBox is bound to a Web service.
In the .cs file where the items are loaded, you can add attributes to the RadComboBoxItemData object and in the client SelectedIndexChanged event do the following to set text in the input area:

function OnClientSelectedIndexChanged(sender, args) {
    var item = args.get_item();
    if (item != null) {
        sender.set_text(item.get_text() + " + " +
        item.get_attributes().getAttribute("test"));
    }
}

(See attached files.)

I hope this helps.

All the best,
