From right to left in textBox (asp.net)?

How do 开发者_如何学JAVAyou achieve this. and i set some text inside the textbox. i want it to be lower in opacity and disappear whenever the user clicks on the textbox to begin typing (like in iphone interface). How do i achieve this?

You can use ajax water mark control and jquery autoclear plugin

In html5 a new attribute introduced placeholder, you can make use of this attribute

In aspx markup your TextBox is

<asp:TextBox runat="server" ID="TextBox1"></asp:TextBox>

Then in Page_Load set the attribute.

TextBox1.Attributes.Add("placeholder", "you faded text like in iphone");

Edit 1:

You are right, for right to left text you need to add another dir attribute on TextBox

<asp:TextBox runat="server" ID="TextBox1" dir="rtl"></asp:TextBox>

For the watermark there is the HTML5 placeholder attribute or you could also use a jquery watermark plugin if your site is not yet HTML5. For right to left you may take a look at the following article.

Do it using java script. See the code below:

1. set a default text for your textbox.

2. for clearing the textbox call the following function on textbox onblur event

   function ClearSearchText() {
       var searchUserName = document.getElementById('<%=txtUserName.ClientID%>');         
   
           if (searchUserName.value = searchUserName.defaultValue) 
           {
               searchUserName.value = "";
           }
   
   
       return false;
   }
   

3. for setting call the following function on textbox onFocus event

       function SetSearchText() {
   
       var searchUserName = document.getElementById('<%=txtBoxID.ClientID%>');
   
   
           if (searchUserName.value == "") 
           {
               searchUserName.value = searchUserName.defaultValue;
           }
       }
   
       return false;
   }   
   

4. do the search in button postback after checking the default text and also set the textBoxID.Text="your default text".

hope this will help..
