Hello, The following example demonstrates an issue with the AutoDataBind property on the ComboBox ExampleController.cs: namespace Web { public class MyClass { public string Name { get; set; } public string Select { get; set; } } } namespace Web.Controllers { public class ExampleController : Controller { public ActionResult Index() { return View(new MyClass { Name = "Timothy", Select = "One" } ); } } } Index.aspx: <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<Web.MyClass>" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Example</title> </head> <body> <ext:ResourceManager ID="ResourceManager1" runat="server" /> <ext:TextField ID="TextField1" runat="server" AutoDataBind="true" Text="<%# Model.Name %>" /> <ext:ComboBox ID="ComboBox1" runat="server"> <Items> <ext:ListItem Text="One" Value="One" /> <ext:ListItem Text="Two" Value="Two" /> <ext:ListItem Text="Three" Value="Three" /> <ext:ListItem Text="Four" Value="Four" /> <ext:ListItem Text="Five" Value="Five" /> </Items> <SelectedItem AutoDataBind="true" Text="<%# Model.Select %>" /> </ext:ComboBox> </body> </html> Replication steps: 1. Load page 2. Notice Timothy has been populated but One in the ComboBox has not Cheers, Timothy ---- Timothy Grant Vogelsang tvogelsang [at] esolutionsgroup [dot] ca Project Manager / Senior Software Developer Microsoft .NET Framework 3.5 Coolite Toolkit 1.0 Permalink: Post #28636

Hi, Selection is possible by value only (Text property is used for reading, after submit to read the text of the selected item) Therefore please use Value property only <SelectedItem AutoDataBind="true" Value="<%# Model.Select %>" /> -- Vladimir Shcheglov Coolite Inc.

Thanks for the information on the Text field. I've tried the Value field and I have the same result, not working. Can you confirm on your end?

Hi, Investigating... Under MVC the AutoDataBind doesn't work for SelectedItem -- Vladimir Shcheglov Coolite Inc. Development Team Forum Guidelines \| Coolite Examples \| Coolite API Docs \| ExtJS API Docs \| Twitter Permalink: Post #28647

Thanks vladsch! Question for you, when I submit a form with a ComboBox named ComoBox1 the values that are sent are the following: ComboBox1 = Text value ComboBox1_SelIndex = Index value ComboBox1_Value = Value Would it be possible to switch make the value for ComboBox1 be the actual value? And remove ComboBox1_Value and add ComboBox1_Text? Would be helpful.

Yeah, I would really like to see that happen too. I guess it would break existing code though. Maybe an optional attribute could enable such behavior? --- Sandor Drieënhuizen Subspace Permalink: Post #28662

Would be nice if we could have an option to ommit the additional values from being submitted in the post. For example, when I have 10 combobox fields on a page it's sending 30 values back to the server -- when 20 of them are useless Cheers, Timothy ---- Timothy Grant Vogelsang tvogelsang [at] esolutionsgroup [dot] ca Project Manager / Senior Software Developer Microsoft .NET Framework 3.5 Coolite Toolkit 1.0 Permalink: Post #28667

Argh, would be extremely useful because now my TryUpdateModel fails miserably Let me know what you think vladsch.
