This is the error Conversion failed when converting the varchar value 'f' to data type int. what i need is wen i enter in "first" textbox and hit the button search,for the remaining textboxs like middle & last the data has to be retrived into it.Now its giving error saying cannot convert varchar to int.I had given datatype as for all the fields in database as "varchar(50)". And now i created in database three fields called first,middle,last also i gave values for those fields.
#C# write to textbox windows
I created in windows application,one form in that i had created three labels (first,middle,last) & infront of that i created textboxes with Search button in bottom.
I was using my way,but i made a slight change according to you,even though it is not retriving.
