Hi,

I am trying to update an existing asp.net page and have added a textbox to capture a field to SQL.

When i try to build the application the following comes up after adding the textbox:

error BC30451: Name 'TextBox4' is not declared.

there is no errors in the code I have written but this keeps popping up for some reason. I have no duplicate pages and have checked that the textbox is being refered to the correct page.

Does anyone have an idea as to why this happens and what is a solution to remedy this issue?

thanks.

Try deleting the textbox and add it again from toolbox with same ID.

Check for the ID of the text box in the designer class of the page. I am sure that the Text box instance with that ID is not declared there. Add the text box with your respective ID in the designer class and it will solve your problem.

This happens usually when you tries to add the control when the application is running.
