Why is one of my aspx TextBox values not transfering to my C# code?

I have an ASPX webform that takes some data and just sends an email. It has worked for years but I just added a new field and I can't get the Text value to transfer to the c# code that writes the email.

The difference is that the new field is populated through jQuery/JSON look-up and it is read-only. The jQuery portion is working fine.

TextBox in question:

<asp:TextBox ID="autoRegion" Width="30" ReadOnly="true" onfocus="this.blur();" TabIndex="-1" CssClass="disabledInput" Value="" runat="server" />

Working TextBoxes:

<asp:TextBox ID="FName" MaxLength="40" TabIndex="1" runat="server" />
<asp:TextBox ID="LName" MaxLength="40" TabIndex="3" runat="server" />

C# variable for email body content:

objMM.Body += "<table><tr><td>" + 
     LName.Text + "</td><td>" + FName.Text.ToUpper() + "</td><td>" +
     streetAddress1.Text + "</td><td>" + city.Text.ToUpper() + "</td><td>" +
     state.SelectedItem.Text + "</td><td>" + zip.Text + "</td><td>" + autoRegion.Text +
     "</td></tr></table>";

All other fields are working but autoRegion.Text is not.

I have also tried filling a variable with Request.Form["autoRegion"] and using that variable in place of autoRegion.Text but that did not work either.

Any help would be appreciated.

Mark Fitzpatrick is right, the problem is you are setting that TextBox to ReadOnly, which means its value is not persisted in ViewState.

Here is a potential workaround: Disabled textbox losses viewstate

Edit: Also Strange behavior using HTML 'readonly="readonly"' vs. JavaScript 'element.readOnly = true;'

Check out this link: ASP.NET textbox losing value after postback when value is changed client-side via javascript. It appears that the postback only pushes the ViewState data for a TextBox that is either Disabled or ReadOnly. Because you are loading the value via client-side, there is nothing in the ViewState for your TextBox.

There are several different work-around, but I would attempting the answer to this question:

protected void Page_Load(object sender, EventArgs e)
{
    TextBox1.Attributes.Add("readonly", "readonly");
}

In addition to applying this code, you would need to remove the ReadOnly="true" property from the TextBox on the aspx page.

If I remember correctly, read only items do not have their values posted back to the server since there would be no reason since they cannot be changed.
