@Html.TextBoxFor for repeated properties in the model
Please help me solve this problem. I am currently trying to do this in MVC3, VB.NET.
Consider the following model:
Public Class SampleData
Public Property PTY_1 as String
Public Property PTY_2 as String
Public Property PTY_3 as String
'...开发者_开发百科snipped
Public Property PTY_19 as String
Public Property PTY_20 as String
End Class
Currently in my view, I have the following code:
<tr><td>@Html.TextBoxFor(Function(model) model.PTY_1)</td></tr>
<tr><td>@Html.TextBoxFor(Function(model) model.PTY_2)</td></tr>
<tr><td>@Html.TextBoxFor(Function(model) model.PTY_3)</td></tr>
'...snipped
<tr><td>@Html.TextBoxFor(Function(model) model.PTY_19)</td></tr>
<tr><td>@Html.TextBoxFor(Function(model) model.PTY_20)</td></tr>
As you can see, this will require 20 lines of code in my view. Is there a way to use a for-loop instead so that my view has fewer lines? Thanks.
Update 1. I have tried adding a new property PTY to my model to access the properties based on an index. Thus PTY(2) = PTY_2.
Public Class SampleData
Public Property PTY(index as Integer) as String
Get
Select Case index
Case 1 : Return PTY_1
Case 2 : Return PTY_2
Case 3 : Return PTY_3
'...snipped
Case 19 : Return PTY_19
Case 20 : Return PTY_20
Case Else : Return ""
End Select
End Get
Set (value as String)
Select case index
Case 1 : PTY_1 = value
Case 2 : PTY_2 = value
Case 3 : PTY_3 = value
'...snipped
Case 19 : PTY_19 = value
Case 20 : PTY_20 = value
End Select
End Set
End Property
End Class
And as for the view, I have tried the following code:
@For index as Integer = 1 to 20
<tr><td>@Html.TextBoxFor(Function(model) model.PTY(index))</td></tr>
End For
However when I load the view, I am getting an InvalidOperationException: "Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions." T_T
You could decorate your properties with the [DataType(DataType.MultilineText)]
attribute and in your view:
@Html.EditorForModel()
and if you want you could customize the template by using the [UIHint]
attribute:
<DataType(DataType.MultilineText)> _
<UIHint("CustomTextArea")> _
Public Property PTY_1 as String
...
and then define an editor template (~/Views/Shared/EditorTemplates/CustomTextArea.cshtml
):
<tr><td>@Html.TextArea("")</td></tr>
The matter is PTY_1 to PTY_20 is the names of your future inputs.
I write in C# :)
@for (int i = 1; i <= 20; i++)
{
string name = "PTY_" + i;
<tr><td><input type="text" name="@name" /></td></tr>
}
