Dot Net Code Snippets

Hi , Now we have to discuss about the watermark the textbox using javascript

for that you have to use onblur and onfocus property of your textbox

<script type = "text/javascript">

   var defaultText = "Enter your text here";

   function WaterMark(txt, evt)

   {

       if(txt.value.length == 0 && evt.type == "blur")

       {

           txt.style.color = "gray";

           txt.value = defaultText;

       }

       if(txt.value == defaultText && evt.type == "focus")

       {

           txt.style.color = "black";

           txt.value="";

       }

   }

</script>

Here is the HTML Code of the Textbox control

<asp:TextBox ID="TextBox1" runat="server" Text = "Enter your text here"

   ForeColor = "Gray" onblur = "WaterMark(this, event);"

   onfocus = "WaterMark(this, event);">

</asp:TextBox>

Now we have to write the attributes through code on your Page_load Event

TextBox1.Attributes.Add("onblur", "WaterMark(this, event);")

TextBox1.Attributes.Add("onfocus", "WaterMark(this, event);")

Hi Use this code.

 <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
       <asp:RegularExpressionValidator
       ID="valUserName" runat="server" ControlToValidate="TextBox1"
       Display="Dynamic" ErrorMessage="Minimum length 6 characters"
       ForeColor="" ValidationExpression=".{6}.*" ></asp:RegularExpressionValidator>
