Hi, Please try the following code:
Code: JavaScript
//Call this function to display the dialog
function showDialog()
{
eo_GetObject("Dialog1").show();
}
//This function is called by the dialog when
//it is shown.
function init_dialog(dialog, arg)
{
//Get the textbox you wish to focus. Note
//the server code syntax here
var textBox = document.getElementById('<%=Dialog1.ContentContainer.FindControl("TextBox2").ClientID%>');
//Set the focus to the textbox. A slight
//delay is needed because the dialog always
//try to set the focus to the first input
//element. So our focus code must be run
//after that
setTimeout(
function()
{
textBox.focus();
}, 200);
}
Code: HTML/ASPX
<a href="javascript:showDialog();">Show Dialog</a>
<eo:Dialog id="Dialog1" ClientSideOnInitDialog="init_dialog" ....>
....
</eo:Dialog>
Note the dialog's ClientSideOnInitDialog is set to "init_dialog", which is the name of the JavaScript function that focus the textbox. Thanks!

Please remove the following comment line:
Línea 27: //the server code syntax <%= %> here
That is meant to be a comment line but ASP.NET picked up "<%= %>" in the comment and does not like it.
Thanks

Hi, That is something else. It basically complains that you can not use server code block (<%= %>) and trying to modify the parent control's control collection (usually because you want to dynamically create controls) at the same. This is a generic ASP.NET restriction and it has nothing to do with us. The issue is triggered because you are modifying the control collection, and our sample code uses server code block. In order to resolve the issue, you need to remove at least one. There are many ways to remove server code block from our code, all of which is related to general ASP.NET/JavaScript programming and none is particular related to us. One way you can try is: 1. Add the following code in your server side code: Page.RegisterClientScriptBlock("control_to_focus", string.Format("<script type='text/javascript'>var control_to_focus='{0}';</script>", Dialog1.ContentContainer.FindControl("TextBox1").ClientID)); This stores the ID of the TextBox control you want to focus inside a JavaScript variable "control_to_focus"; 2. Change the client side JavaScript code to:
Code: JavaScript
var textBox = document.getElementById(control_to_focus);
This way it removes the server code block that was used by getElementById. And your original problem should go away. Thanks!

Hi,
I solve this problem placing the text box as the first control of the dialog on the *.aspx page code. It works fine for me, and is a lot easier to do.
Thanks
