error on editing data!

[mammad_k]

Hi, I am having a problem with editing data in browser preview. I have a datagrid with only one data column which is not read only and users should be able to edit it. I have an "edit" button in front of the row which becomes “Update” and “Cancel” buttons on Click. The cancel button works fine but when I make some changes and press update it gives me this error: System.FormatException: Input string was not in a correct format. at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) at DreamweaverCtrls.DataSet.ConvertParameterValue(String strValue, Enum theType) at DreamweaverCtrls.DataSet.OnDataGridUpdate(Object Src, DataGridCommandEventArgs E) Any idea what it is for? Thank you in advance.:) Mammad

hi, mammad_k wrote: System.FormatException: Input string was not in a correct format. at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) these tho lines mean that somewhere you are trying to convert string to integer and it is not possible... Run in debug mode and check line where it happens... there will be incorrect input to some functions or so. eh.. does it help? best regards, David 'DNH' Nohejl Never forget: "Stay kul and happy" (I.A.)

Hi David, How can I run in debug mode?

I still dont know how to run it in debug mode but as you said there was some problems with integer data type. I just changed the Integer to VarWCahr and every thing is sorted. That was a great help, thanks;) mammad

:doh: I could ask... what kind of IDE do you use? VS.NET? Web Matrix? or what? If it is VisualStudio, hit F5 (or Debug->Run from main menu)... ( first check if project configuration is set to debug - Build->configuration manager...) If you are using soemthing else check help manual. When running in debug mode, additional debug information are generated for your code and e.g. exceptions' stack trace will contain line numbers. Plus you can use breakpoints to pause program and look at variables and their values etc... Kind of basic thing so if you already know this.. sry then :-O one never knows who is on the other side;) David Never forget: "Stay kul and happy" (I.A.)
