Hi,
Sorry if I missed this in the documentation or in the forum topics: is putting asp .net DropDownList control inside the DropDownTemplate of ComboBox supported?
The control renders, but I cannot choose any items - I guess the dropdown of that DropDownList somehow interferes with the DropDownTemplate? How can I make this work?
Thanks in advance!

Hi, You can put anything inside the DropDownTemplate of a ComboBox control, but you have to call this function to notify the ComboBox of the new value: http://www.essentialobjects.com/doc/1/jsdoc.public.global.eo_setcomboboxvalue.aspxThe only exception to this rule is if you put a EO.Web ListBox control in it. An EO.Web ListBox knows EO.Web ComboBox so it will automatically call the above function for you. Thanks!

Not sure if I understand. For every value of of the DropDownList in the template, I have to call this function? Could you post some sample code that will correctly put a DDL inside the DDTemplate with, let's say, 2 static values?
Thank you!

Hi, Try to think the ComboBox as JUST a simple TextBox. The rule is wheneer you want to update the TextBox, you update it. How many values you have in your DropDownList, or whether you use a DropDownList at all is irrelevant. Here is a working example. You can take a look of the source code of the sample to see how it works. http://demo.essentialobjects.com/Demos/ComboBox/Features/Drop%20Down%20Template%20-%20Advanced/Demo.aspxThanks!

I'm not explaining myself well at all :) I get the idea of retrieving the value from the DropDownTemplate from a control to the "text" area of the combox, but it's not my issue. I can't get past the simple stuff here:
<eo:ComboBox ID="ComboBox1" runat="server" Width="150px" ControlSkinID="None"
DefaultIcon="00101070" HintText="Type here">
<DropDownTemplate>
Some text
<br/>
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem>Item1</asp:ListItem>
<asp:ListItem>Item2</asp:ListItem>
</asp:DropDownList>
</DropDownTemplate>
<IconAreaStyle CssText="font-family: tahoma; font-size: 12px; border-left: solid 1px #a8b1c6; border-top: solid 1px #a8b1c6; border-bottom: solid 1px #a8b1c6; vertical-align:middle;padding-left:2px; padding-right:2px;" />
<IconAreaHoverStyle CssText="font-family: tahoma; font-size: 12px; border-left: solid 1px #0a246a; border-top: solid 1px #0a246a; border-bottom: solid 1px #0a246a; vertical-align:middle;padding-left:2px; padding-right:2px;" />
<HintTextStyle CssText="font-style:italic;background-color:#c0c0c0;color:white;line-height:15px;" />
<TextAreaStyle CssText="font-family: tahoma; font-size: 12px; border-top: solid 1px #a8b1c6; border-bottom: solid 1px #a8b1c6; vertical-align:middle;padding-left:2px; padding-right:2px;" />
<TextAreaHoverStyle CssText="font-family: tahoma; font-size: 12px; border-top: solid 1px #0a246a; border-bottom: solid 1px #0a246a; vertical-align:middle;padding-left:2px; padding-right:2px;" />
<IconStyle CssText="width:16px;height:16px;" />
<ButtonAreaStyle CssText="border: solid 1px #a8b1c6; vertical-align:middle;" />
<ButtonAreaHoverStyle CssText="border: solid 1px #0a246a; vertical-align:middle;" />
<ButtonStyle CssText="width:14px;height:18px;background-color:#dee1e7; background-image:url(00020012); background-position: center center; background-repeat: no-repeat;" />
<ButtonHoverStyle CssText="width:14px;height:18px;background-color:#b6bdd2; background-image:url(00020012); background-position: center center; background-repeat: no-repeat;" />
</eo:ComboBox>
I'm not able to select "Item2" at all.
Sorry, I should've posted code earlier.

This is in fact exactly your issue. You need to figure out these following: 1. How to handle a "select" event from your own drop down UI on the client side with JavaScript (in this case it would be your DropDownList); 2. How to get your current selected value from your own drop down UI in your event handler; Once you got those two working, you can just pass the value to our ComboBox. We do not provide support on these two issues because we consider them generic ASP.NET programming question ---- just replace our ComboBox with a simple textbox and you would have exactly the same question (and solution). As such from our point view, we only tell you how to pass the value to our ComboBox, not how to get the current selected value from your own custom UI. I also do not understand why you want to put a DropDownList inside a ComboBox's drop down. That seems to be redudant to me as you will have two levels of drop downs. Thanks!

You're digging too deep, I'm stuck on the trivial stuff. That little down arrow on the generic DropDownList control that lets you EXPAND and see all the items (before you even click and select them) - I'm not able to click on that. Try the code I've posted.
As far as having two dropdown lists, I like the flexibility of ComboBox and I'm building a pretty complex dropdown panel with checkboxes, radiobuttons and dropdowns...so far the only control I'm having difficulty with is DropDownList

Sorry, spoke too soon: Chrome and FF 13 are fine; IE 9 still has the same issue
