Hi can anyone help me in exporting a datagridview to an excel. I want to display in excel in specific format, like each row in datagridview should be displayed as columns in excel. File name should not be defined in the code behind. The user should be able to dynamically defined in the save file dialog box.
how can i save cell values to text file with delimiteri have 9 rowsand i have this code
then on my text file i want to save like this format
but im failedand the result i've got on my text file is like this
Your newoutputlines
still have previous values. You need to clear it every time you add new row
But i want to show my approach to save values in the file by using StringBuilder
. If you will have a lot of rows then this approach will be more efficient.
