validate max length in asp text box having multi line as well as text area in html

for test use this
<div>
<asp:TextBox ID="txtAddresss" TextMode="MultiLine" onchange="if (this.value.length > 1) {alert('onchange event');this.value=this.value.substring(0,1); return false; }" onkeypress="if (this.value.length > 1) {alert('onkeypress event');this.value=this.value.substring(0,1); return false; }" runat="server"></asp:TextBox>
<br /><textarea id="txtAddresss1" onchange="if (this.value.length > 1) {alert('onchange event');this.value=this.value.substring(0,1); return false; }" onkeypress="if (this.value.length > 1) {alert('onkeypress event');this.value=this.value.substring(0,1); return false; }"></textarea>
</div>

For Implementation use this

<asp:TextBox ID="txtAddresss" TextMode="MultiLine" onchange="if (this.value.length > 1) {alert('onchange event');this.value=this.value.substring(0,1); return false; }" onkeypress="if (this.value.length > 1) {this.value=this.value.substring(0,1); return false; }" runat="server"></asp:TextBox>
<br /><textarea id="txtAddresss1" onchange="if (this.value.length > 1) {alert('onchange event');this.value=this.value.substring(0,1); return false; }" onkeypress="if (this.value.length > 1) {this.value=this.value.substring(0,1); return false; }"></textarea>
