asp:textbox readonly

Question

In asp file I have two asp:textbox

<asp:TextBox ID="textValue" runat="server" Width="100px"/> <asp:TextBox ID="textValue2" runat="server" Width="100px" ReadOnly="true"/>

then I set the value via javascript getting

<asp:TextBox ID="textValue" runat="server" Width="100px" value="aaa"/> <asp:TextBox ID="textValue2" runat="server" Width="100px" ReadOnly="true" value="bbb"/>

but when refresh the webpage finally get

<asp:TextBox ID="textValue" runat="server" Width="100px" value="aaa"/> <asp:TextBox ID="textValue2" runat="server" Width="100px" ReadOnly="true"/>

Why the value bbb is "lost"? How can I avoid this?

With javascript. A tipical example is a Calendar + Input text. — Dr. No

Remove the server side attribute - ReadOnly - from the TextBox and set the HTML attribute from the code. You will be able to access the value then in post back:

textValue2.Attributes.Add("readonly","readonly");

"bbb" is being posted back, but .NET will not populate a read-only textbox from postback data. You can manually populate the text box by grabbing the form data yourself from the Page_Load() method as follows:

textValue2.Text = Request.Form[textValue2.UniqueID];

<asp:TextBox ID="textValue2" runat="server" Width="100px" ReadOnly="true"/>

You are missing a quotation mark before 'true', it might cause issues.

I think instead of readonly, set your value to the textbox and then disable it.
