dropdownlist and button

[sroberts82]

Hi,
I have a form with a dropdownlist on it. I have an eventhandler for OnSelectedIndexChanged which works grand. The problem arises when I try to add a submit button. Form appears fine first time, but when I attempt to change the selected item in dropdownlist, and error comes about saying there is a problem with some JScript error (I imagine added itself I didnt have any Jscript in) saying

function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit(); <-----"object doesnt support this property or method"
}
}

any ideas? Thanks in advance,
Ste

Paste both the HTML and code for the Button and DropDownList

Dropdown list:

<asp:TableRow>
<asp:TableCell><aspropDownList ID="gameGroup" runat="server" Width="204px" OnSelectedIndexChanged="gameGroupSelectionChange" AutoPostBack="true"></aspropDownList></asp:TableCell>
</asp:TableRow>

protected void gameGroupSelectionChange(Object sender, EventArgs e)
{
DropDownList list = (DropDownList)sender;
Session["SelectedIndex"] = new gameGroup(list.Items[list.SelectedIndex].Text, System.Convert.ToInt32(list.Items[list.SelectedIndex].Value), list.SelectedIndex);
Response.Redirect("gamesUploadForm.aspx");

}


Button:
<asp:Button runat="server" ID="submit" Text="Submit" OnClick="submitClick" />


submit code is empty at moment, want to fix this error first

I think the problem is that when the submit button posts back its all fine, the this.submit() means something, but when the dropdownlist posts back it doesnt understand the this.submit. But how to get around it?

The javascript you see is generated by ASP.NET and is used to submit the form. If it is erroring you may have a problem with your installation. Does this happen in all browsers (or just IE)?
