I'm trying to figure out how to reference controls inside a dialog box from client-side javascript. I'm attempting to change the value in a textbox which resides inside the EO dialog box... I want to clear the textbox if the user clicks the cancel button.

Thanks for any assistance.

Hi Ray,

You would use:

document.getElementById("<%=TextBox1.ClientID%>').value = "";

Thanks

I've tried all of these... none work?

function newOrderCancel() {
// Your example... document.getElementById('<%=txtNewOrderOrderno.ClientID%>').value = "";
//'document.getElementById("<%=txtNewOrderOrderno.ClientID%>").value = "";
//NO: eo_GetObject("<%= txtNewOrderOrderno.ClientID %>").value = "";
//document.getElementById("<%=txtNewOrderOrderno.ClientID%>").value = "";
//NO: document.getElementById("txtNewOrderOrderno.ClientID").value='blah blah'
//NO: document.getElementById("<%=txtNewOrderOrderno.ClientID%>").value = "";
//NO: document.getElementById("txtNewOrderOrderno").value = "";
//NO: document.getElementById("<%=txtNewOrderOrderno.ClientID%>").value = "";
//NO: document.getElementById("txtNewOrderOrderno.ClientID").value = "";
}
... and all I get is getElementById is null or not an object...

here's the control reference in the aspx file inside of the (<eo:Dialog ID="DialogNewOrder"... ):

<asp:TextBox ID="txtNewOrderOrderno" runat="server" Font-Names="Tahoma" Font-Size="10pt"
Style="z-index: 105; left: 172px; position: absolute; top: 27px" TabIndex="1"></asp:TextBox>

This is asp.net.... 2005.

Hi,

Do you use ContentTemplate? Try view the page source and get the full ClientID of the textbox, it would be something like "xxxDialogNewOrder_xx_txtNewOrderOrderno", use that value to replace the getElementId argument.

If you do not wish to use hardcoded value, you can replace:

document.getElementById("<%=txtNewOrderOrderno.ClientID%>")

with:

document.getElementById("<%=GetTextBoxClientID()%>")

Here GetTextBoxClientID would be a function you implement:

protected string GetTextBoxClientID()
{
System.Web.UI.Control textbox = DialogNewOrder.ContentContainer.FindControl("txtNewOrderOrderno");
return textbox.ClientID;
}

Note you may need to replace DialogNewOrder.ContentContainer with DialogNewOrder.FooterContainer if the text box is in the dialog's footer template.

Thanks

Thanks, the first option worked: DialogNewOrder_ctl00_txtNewOrderOrderno was the source ID... I tried to use the function... but couldn't get it working... for now... I may visit that later...

Question... being that I 'hardcoded' the ID... does it ever change, or is it static?

Thanks again!

Hi,

The ID won't change unless you change its parent's ID. For example, if you change the Id of the dialog, then the ClientID of the textbox will also change.

Thanks
