Today in the development of an ASP. NET page encountered a TextBox set the ReadOnly property, after the assignment in JS, the background code does not take the value of the case, after searching on the internet, found a few ways to deal with.
Collect them.
1, do not set ReadOnly, set Onfocus=this.blur ()
C # code
<asp:textbox id= "TextBox1" runat= "Server" Onfocus=this.blur () ></asp:TextBox>
<asp:textbox id= "TextBox1" runat= "Server" Onfocus=this.blur () ></asp:TextBox>
The text box is not dimmed, but you cannot modify the content manually, and you can use the Text property to assign values in the background
2. After setting the ReadOnly property, the value is obtained by request, as follows:
Front Code:
<asp:textbox id= "TextBox1" runat= "Server" readonly= "True" ></asp:TextBox>
<asp:textbox id= "TextBox1" runat= "Server" readonly= "True" ></asp:TextBox>
Background code:
String Text = request.form["TextBox1"]. Trim ();
String Text = request.form["TextBox1"]. Trim ();
3, in Page_Load () is setting the text box read-only properties, can read normally, as follows:
C # code
protected void Page_Load (object sender, EventArgs e)
{
if (! Page.IsPostBack)
{
TEXTBOX1.ATTRIBUTES.ADD ("ReadOnly", "true");
}
}
