Solution 1

you are also updating ImagePath and other columns with name column.All will get effected and if you are not selecting any image while updating then the following query gives error.

C#

string str = "update ImagesPath set Name='" + TextBox4.Text + "',Link='" + TextBox5.Text + "',ImagePath='" + "images/" + f + "',Status='"+DropDownList2.SelectedItem.Text+"' where ID='" + DropDownList1.SelectedItem.Text + "'";

So better maintain a flag that will specify either you are doing insert or update..

Thanks

Solution 3

The exception you get is quite clear:
either you do not have specified directory (images) created
or you have created directory but application does not have permissions to access it and save file.

Create the directory and grant write permission to application.
