View 4 RepliesHow would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

I am stuck on how I go about using the nested for loops.Add code in the Draw button�s Click event to create the number of rows and columns selected, using the character selected Use nested For loops to create the rectangle of characters based on the user selections. The outer loop will control the number of rows. Use the value selected in the Rows combo to determine the stopping value of the outer loop. Use the value selected in the Columns combo to determine the stopping value of the inner loop, which controls the number of characters per line.

I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for. Is there a way to edit columns and rows manually ?
This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )
In my datagrid, I know the number of rows that it will have - it will always have 12 rows.Can I scroll through the cells downwards via the columns instead of the usual horizontal way via the rows?

how to print, and got it working pretty well. The text string I have printing into a rectangle, and if a word does not fit it will wrap down to the next line, and then keep going like that, but now I need to split my page into three different areas that will each print different text.I am pretty sure I could draw three different rectangels then draw the text I need on each of them, but is it possible to somehow merge them together into a single rectangle that will be printed?
