Question

I have a view where i am using the:-

@using (Ajax.BeginForm("Edit", "Files", new AjaxOptions
{
HttpMethod = "POST",
InsertionMode = InsertionMode.Replace,
UpdateTargetId = "divFile-" + Model.FileId,
OnSuccess = "editPrivilegeLevelForFileSuccess",
OnFailure = "editPrivilegeLevelForFileFailure"
}))
@Html.HiddenFor(model => model.FileId)

The problem here is the UpdateTargetId:-

My model currently doesnot have FileId value.
I am setting the value of Hidden field by jquery method and it works well.

$("#FileId").val(fileId);

But how can I set the same value in UpdateTargetId?

Thank You

If the value of this property is known only on the client side you could do that inside the OnSuccess callback. So get rid of the UpdateTargetId property from your AjaxOptions and then inside the editPrivilegeLevelForFileSuccess handler you could manually update the corresponding section:

function editPrivilegeLevelForFileSuccess(result) {
    var fileId = $('#FileId').val();
    $('#divFile-' + fileId).html(result);
}
