ASP.NET AJAX RadChat - Change input textbox to textarea

[Gary]

Is there any way I can work around ASP.NET AJAX RadChat control not having a setting for changing the single line input textbox (class=t-input) for message into a multi line textarea?

Hi Gary,

I hope you are doing well!

Thank you for the useful feature request!

Currently, we are using <input type="text"> for a message input area and it does not support multiline capabilities. You can position a textarea with higher z-index over the input and attach its onchange or keydown event to update the input:

<telerik:RadChat runat="server" ID="RadChat1" Skin="Default" >
    <UserSettings Name="John" />
</telerik:RadChat>
<textarea onkeyup="textAreaAdjust(this)" ></textarea>
<script>
    var $ = $ || $telerik.$;

    function textAreaAdjust(o) {
        o.style.height = "1px";
        o.style.height = (25 + o.scrollHeight) + "px";
            $telerik.$(".t-input")[0].value = o.value;
    }
</script>

If you do not like the proposed workaround and its limitations, please do not hesitate to use the feedback portal to submit a feature request for it.
