Asp.net MVC - Model binding image button
- by big dave
I've got a very complex form and i'm using the MVC model binding to capture all the information
I've got it set up to capture all the different submissions that can happen as there are about 10 different submit buttons on the form, and there are also 2 image buttons
I tried to get a bit clever (or so i thought) with capturing the image button submissions, and have created a child class so that i can capture the x value that's returned
public class ImageButtonViewData {
public int x { get; set; }
public string Value { get; set; }
}
The parent class looks something like this
public class ViewDataObject {
public ImageButtonViewData ImageButton { get; set; }
public ViewDataObject(){
this.ImageButton = new ImageButton();
}
}
The html for the image button then looks like
<input type="image" id="ViewDataObject_ImageButton" name="ViewDataObject.ImageButton" />
This works fine in all browsers except for Chrome.
When i debug it in chrome, the Request.Form object contains the values that i would expect, but after the model binding has occurred, the ImageButton property on the ViewDataObject has been set to null
The only difference that i can see between the submission values is that Chrome passes the x as lower case (ViewDataObject.ImageButton.x) and IE passes it as upper case (ViewDataObject.ImageButton.X) but i didn't think that model binding took any notice of casing on property names
Does anyone have any ideas ?
