really need help.....Need logic

hi!

i have profile submission form. in that Category and Subcategory fields are there. both are binded to Dropdown list. actually each Category has many subcategories. so Subcategory will change acc to category dropdown list change. so the user has to select the category. the subcategory will get bind acc to category and the user can select multiple sub category. so far working fine.

now the point is, my client need like, let the user to select multiple categories also then subcategories.

i thought to have like excel sheet. like in a grid view category with chechbox and its subcategory with checkbox so there will be list of category and subcategory listed beside in a gridview. can u tell me any example or is there any easy way to do this.

please suggest.

thanks.
