it should work if the autopostback is true
i tried this one and working fine
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack=true OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
<asp:ListItem>qwewqe</asp:ListItem>
<asp:ListItem>qwewq</asp:ListItem>
<asp:ListItem>qweq</asp:ListItem>

</asp:DropDownList></td>

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList1.Items.Add("Sandeep");
}

function Lookout()
{
alert("Label1 Sandeep Added" );
}

Thanks and Regards

How are you calling the script fucntion?
Tried calling the script function using ddl1.attributes.add("onchange", "javascript:return lookout();")

this way only the script function is being executed not the selection index changed event

yes
i am also calling in samw way
DropDownList1.Attributes.Add("OnChange", "javascript:Lookout();");

i asked you beacause there are two ways you can call javascipt function on button onclick event (AutopostBack=false )and onChange Event (AuotPostBack=true)

Are you sure that the javascript function is working fine and returning true ??

Thanks and Regards

The javascript function is ok i guess!
An alert box will be shown if the condition is met and return false;
else return true thereby the code in the event should be executed - this part is not happenning.

count of web controls on aspx page....

4-Jun-07 1:26

function function1()
{
alert("Hi");
return true;
}

In pageLoad
ddl1.Attributes.Add("onChange", "javascript:return function1();");

The alert box is being displayed but after that the code in the selection changed event is not being executed.

If there are no return statments then both the events are being executed.

So, is it a problem with catching the return true/false??

Hi,
You can try the following code.

int textcount = 0;
foreach ( Control ctrl in Page.Controls )
{
if ( ctrl is TextBox )
{
textcount ++;
}
}

I hope this will help you.

Count refers to the number of textboxes.

Panel is where i put the textboxes,i.e., the textbox are all inside the Panel.

HI,

Create a public property in your webusercontrol which gives u the value of the textbox.

public string TextValue
{
get{ return textbox.text; }
}

now you can use this property in your aspx page like this.

Strint str = WebUserControl1.TextValue;

I hope this will help u.
