Cannot implicitly convert type 'string' to 'System.Web.UI.WebControls.TextBox'
I faced this issue yesterday,it was very strange because it
doesn't make sense at all.
I have a master page and 1 content page,in that content page
there is only one TextBox and an Ajax Editor (from ASP.NET
AJAX Control Toolkit),no more no less.
I tried to run the page but the debugger doesn't compile at
all,it keeps showing this error message:
Cannot implicitly convert type 'string' to 'System.Web.UI.WebControls.TextBox'
It was hopeless,there isn't any server side code or even any
JavaScript blocks,nothing!
After a long analysis at the source/html of my page and
trying every possibility I finally found what caused the
issue that I won't guess it at all:
EMPTY TITLE for my content page
That is what caused the issue,I was surprised,after
removing/setting a value for the title the problem
solved!
I hope my experience with this issue might help someone
else,if anyone face the same issue and solved it in the same
way or in a different way then please post it here,this will
surely help others as well.
