[Solved] autocomplete textbox shows the value 'System.String[]'

[Borislav]

When the page loads the autocomplete textbox shows the value 'System.String[]' .

// simple List<string>
List<string> firstName = new List<string>();
firstName.Add("Bob");
firstName.Add("Bill");
firstName.Add("Denny");
firstName.Add("Dennis");
ViewData["firstname"] = firstName.ToArray();

// in view
<% Html.Telerik().AutoComplete()
 .Name("FirstName")
 .BindTo((IEnumerable<string>)ViewData["firstname"])
 .Filterable(f => f.MinimumChars(2).FilterMode(AutoCompleteFilterMode.StartsWith))
 .HighlightFirstMatch(true)
 .AutoFill(true)
 .HtmlAttributes(new { @style = "width:200px;" })
 .Render(); %>

Hello Borislav,

This is expected behavior. When component is renderинг, it tries to retrieve value with ViewData.Eval(Component.Name), in order to preserve posted value. Hence if the array of items has the same name as the component, then it will be retrieved.

I will suggest you change the name of the array:

// simple List<string>
List<string> firstName = new List<string>();
firstName.Add("Bob");
firstName.Add("Bill");
firstName.Add("Denny");
firstName.Add("Dennis");
ViewData["firstnameArray"] = firstName.ToArray();
