There is a problem in striking today. Text box can only go on the home select data. Cannot be entered manually. I looked it up. The final solution is as follows.

Page code:

<asp:TextBox ID="txtcategory" readonly="true" Width="300" CssClass="txt" runat="server"></asp:TextBox>

Script (used when assigning values to text boxes) :

$("#id").removeAttr("readonly"); //Remove the readonly attribute
$("#id").val( "Your value" );
$("#id").attr("readonly","readonly"); //Add the readonly attribute

So you have this little feature [/ code]
