I have 2 dgv's on a form that are both alike and even use the same datasource, just one column is different betwenn the two.I manually added the columns and set the datasource and bindings. When I make a change to the properties in one of my dgv's it keeps auto generating the columns I do not need.

View 1 RepliesI have a datagridview and I'd like to write it to a file in the same type of row and column format it's currently in.My first idea for doing this is to get the maximum number of characters in each column so i know how wide each column has to be formatted. Then loop through each row and write out each row while using the max characters in each column and the current cells content length to do the math to get the formatted columns to line up. Like the example below, except i'd have a lot more in it.
writer.WriteLine("{0,0}{1," & lb(2).Length + 50 - lb(1).Length & "}", lb(1), lb(2))
This takes label(1) and label(2) and writes them so no mater the length of either (to an extent) then will always be right hand aligned in two columns.

Part of the project needs me to capture data, for example, email address, from certain rows/columns of a datagridview and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). I am familiar with doing these in web form but windows form are different and i am not familiar with it.

View 1 RepliesI would like for my datagridview to automatically fill in the column's next row with the previous entry + 1 letter. So say my datagrid is like this:
ID NextField
15-3A xxxxx
15-3B xxxxx
15-3C xxxxx
Everything is working fine if I type it in but would be nice if the user didn't have to type this each time and just have it fill in the next consecutive ID automatically when you press down to start a new row. Also i need it to work no matter what gets typed in... so if I make another ID 15-4A it will start filling in 15-4B etc. on each new row.
