Get java script value from asp.net custom control textbox

Question

I have developed an asp.net custom control using text box, and its used in different places in a form, how can i get the text box value from different custom control.

I am using following syntax but its not working.

following propetly added to custom control class -

public TextBox ObjTextBox
{
    get { return objTextBox; }
}

following code using to get custom control value

<script type="text/javascript"> 
    function met1() { 
        var objTextBox = document.getElementById('<%=MyTextBox1.ObjTextBox.ClientID %>'); 
        alert(objTextBox.value); 
    } 
</script>

its saying floowing error - ": 'string' does not contain a definition for 'ClientID' and no extension method 'ClientID' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)" — ramya

appears that MyTextBox1.ObjTextBox is string. try this: <%=MyTextBox1.ClientID %> — karaxuna

Add a property on your custom control as:

public string TextBoxClientID
{
   get 
   { 
     return objTextBox.ClientID; 
   }
}

And use this property as:

var objTextBox = document.getElementById('<%=MyTextBox1.TextBoxClientID %>');
