ReadOnly TextBox in Update Panel

**RajWolf** · September 4th, 2009, 11:18 PM

I have a ReadOnly TextBox in an update panel along with several.

I am loading some value using Ajax & Webservice to the TextBox so that it will be displayed to the user and not for changeing it .

On Click of save button i am storing all the TextBox values along with this readonly textbox
to database but the value is blank while reading in .VB page.

What could be the problem , any HELP please

if you are only displaying data for a user to view and not be able to edit, you should use a label instead of a textbox.

No, the same problem with the label also. i have tried it

What i am doing is , as the user selects the itemname, i am loading the rates of it with Javascript function calling webservice i.e. ajax , the rate displays, but when he clicks submit , i get the value of the label or textbox as it was in the begining of the page load

Hey , yesterday i worked out and came to know that the problem is not only with the update panel, normally it happens that way

i have done an example page to show the problem, i have taken 2 text box txtval1 and txtval2
and summing them using javascript function, the answer is displayed in a label(lblsum) and read only textbox(txtsum). When i submit and try to read the sum it doesn't

here is the default2.aspx code

Try not to make the textbox directly readonly by changing its properties.
Try this one.It works.

txtsum.Attributes.Add("readonly", "readonly")
