I have a couple of drop down list inside a update panel and a asp:menu. When the site is accesed with IE6 the asp:menu appears behind the dropdown combos. I already try fix it with z-index but nothing happen, the dropdown still appears in front of asp:menu. is a bug in IE6, or there is a workaround? This not happen with IE7, IE8 and Firefox.
View 1 RepliesI am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.

I have 2 drop down lists.I have a very simple dropdown list #1 that diplays a title and holds an id value which is a GUID.I know it is getting this value and sending this value as I tested sending it to a label.I have the dropdown list #1 to autopostback to dropdown list #2 that "Is supposed to get" another title and value based on the GUID value of the first dropdown list. for some reason it wont return anything. I have done 100's of these but never based off a guid value.I assume the value needs to be converted to guid before selecting it in the second dropdown list.How can I do this? or is there something I am missing?

View 4 RepliesClicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.

View 10 RepliesI have a asp:menu that's using data from a .sitemap file. This site is running on server 2003 asp.net 2.0. I assume IIS v6? When using IE9 normally the dropdown menu shows but you can't select anything from it (the pointer goes away when you hover over it) and it disappears. If you go into Compatibility mode, the dropdown menu shows and you can access the menu items but the item hover background color is lost (supposed to be white with #CC0000 text. Background is #CC0000 so you can't see the text).
This didn't happen with any other versions of IE. If you check it in any other browser, it works as expected.
Funny thing is if I run it out of my local IIS v7 (Win7) or my dev server from VS 2010 (localhost), it works fine in IE9.

However, I have page where there is an image gallery built as a flash object just below the top tier of the menu. If I click on an item that has submenu items the drop-down items go behind the flash object and you can't see them to click on them.The menu is defined in the masterpage. how to get round this without moving / changing the look of the page. Can the menu be set to be in front of the flash object?

I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.
View 1 RepliesI have a Cascading drop down list that is working fine to load the correct lists however I would like to have the last one initiate a query and display a datagrid on the same page containing the results of the query. Without Ajax involved this seems rather easy by using autopostback on the drop downs. If I could do it through Ajax that would be great but I can settle with having the page to reload to display the data. Right now I'm not sure how to do either. I enabled autopostback on the last drop down and wrote a method for it but I get an error at runtime saying:
Invalid postback or callback argument
I'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
<asp:DropDownList ID="ddlFilter" runat="server" >
<asp:PlaceHolder ID="ListItemPlaceholder" runat="server"/>
</asp:DropDownList>
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
<mytag:MyControl Mode="DropDown" runat="server">
<ListItemTemplate>
<asp:ListItem Text="C" Value="c"></asp:ListItem>
<asp:ListItem Text="E" Value="e"></asp:ListItem>
<asp:ListItem Text="B" Value="b"></asp:ListItem>
</ListItemTemplate>
</myTag:MyControl>
I know I can do this by dynamically adding the ListItems in the page code behind, but I'd like to avoid that if possible.
I have drop dowm menu as follow.
<asp:ListItem Value="">none</asp:ListItem>
<asp:ListItem Value="STO">Stock</asp:ListItem>
<asp:ListItem Value="ORD">Order</asp:ListItem>
If I chose none, it stores data as "Null" If I Query the data as below, I don't get the data has value of "Null" SELECT tabale From type Where type <> STO or type <> ORD I get data that has empty string but not Null.
1, How do I write dropdown menu value in oder to get empty string instead of Null?
I did <asp:ListItem Value="">none</asp:ListItem> but this stores Null.
2, Why this Query won't pick up Null?
SELECT mytabale FROM type WHERE type <> STO or type <> ORD
