Re: Get the first and last row for each child row

Yes ... Repeater has that option. Acutally everything in repeater is created by you. Just use PageDataSource to handle paging. Place values in ViewState and use HeaderTemplate and FooterTemplate to have first and last row.

You might give it a try... Rose | [Rose]

Hiding AJAX extender icon

I have created a user control that uses an AJAX extender. The problem is when I place the user control on a page a rectangle shaped CalendarExtender icon is shown in the designer. This moves other controls out of place in the designer making it hard get things lined up correctly. When the page runs the CalendarExtender icon is not shown but how can I removed it in the designer?

Why do you use Designer?

I think using it will end up creating unnecessary codes. use html to define design. Smile | :)

Hi all,

I am a beginner in javascript, and now I am trying to use it to check validation for an aspx page. I have a button and a textbox. When the button is clicked, the textbox will be checked wether it is empty or not.

I use the following code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript" runat="server">
      function checkValue2( obj)
{
    if (obj.value == "")
        alert ("empty");
    else
        alert ("not empty");
}
</script>

</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>              
        <asp:Button ID="Button1" runat="server" Text="Button"  onclick='checkValue2(forms[0].TextBox1)' />  
    </div>
    </form>
</body>
</html>

And this is the error:

Compiler Error Message: CS1001: Identifier expected

Source Error:

Line 7: <title>Untitled Page</title>
Line 8: <script type="text/javascript" runat="server">
Line 9: function checkValue2( obj)Line 10: {
Line 11: if (obj.value == "")

Could you tell me how can I fix this error?

Thank kiu so much!

Try This :

var TextID="<%TextBox1.ClientID")";
 function checkValue2()
{
    Var ClientTextID= document.getElementByID(TextID);
    if(ClientTextID.value='')
      {
       alert('text box is null);
      }
     else
      {
      alert('text box is not null);
      }
}

Please check the syntax. Smile | :)

Suggested change should be done in OnClientClick Event

<asp:Button ID="Button1" runat="server" Text="Button" 
OnClientClick='checkValue2(forms[0].TextBox1)' />

I have placed it in my code as following

<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript" runat="server">
      var TextID="<%TextBox1.ClientID")";
        function checkValue2()
        {   
            Var ClientTextID= document.getElementByID(TextID);
            if(ClientTextID.value='')     
            {     
                alert('text box is null);     
            } 
            else    
            {    
                alert('text box is not null);   
            }
        }
</script>
</head>

But it seems to be wrong?

Re: using javascript to check validation in aspx page

The only problem that I see in your code is runat="server" in the script block.

If you specify a script block as runat="server" it will take it as C# / VB.NET block based on the language.

So remove the runat = server and also use
OnClientClick to define javascript block.

use this :

<asp:Button ID="Button1" runat="server" Text="Button"  OnClientClick="javascript:checkValue2(this)" /> 

<script type="text/javascript" >
function checkValue2( obj)
{
    if (obj.value == "")
        alert ("empty");
    else
        alert ("not empty");
}
</script>

this will work. Wink | ;)

do not use expression in CSS...

Browser renders it for every action, thus the site will be slower. Even mouse-move will call it also. Smile | :)
