如何使用添加和删除行按钮在Gridview中添加Combobox和文本框？

我想要gridview添加，删除，编辑按钮，gridview应该包含组合框和文本框..

组合框将填充数据库中的值，并且应该有selectedindexchanged事件..

文本框也应该有textchanged事件..



请参阅以下senario：在gridview中，



添加 编辑 删除 | column1 | column2 |第3栏



添加 编辑 删除 | combobox1 | textbox1 | textbox2



_______________________________________________________________________________

总计：textbox3 =加法（textbox2）





组合框包含％的比率，如2％，3％，4％等等



和文本框验证只允许数字



然后，



十进制总数= Convert.ToDecimal（textbox1.Text）* Convert.ToDecimal（ combobox1.SelectedValue / 100）;

TextBox2.Text = total.ToString（）;



textbox3.text =第3列中的总数




Plz help..URGENT ..

Jquery和Javascript首选..Plz ..因为它会在加载中花费这么多时间并添加/编辑/删除按钮

I want gridview with add,delete,edit buttons and also gridview should contain combobox and textbox..
combobox is to be filled with values from database and should have selectedindexchanged event..
textbox should also have textchanged event..

See the following senario : In gridview,

add edit delete | column1 | column2 | column3

add edit delete | combobox1 | textbox1 | textbox2

_______________________________________________________________________________
Total: textbox3 = addition(textbox2)


combobox contains rate in % like 2%, 3%, 4%... etc

and textbox have validation to allow only numbers

then,

Decimal total = Convert.ToDecimal(textbox1.Text)*Convert.ToDecimal(combobox1.SelectedValue/100);
TextBox2.Text = total.ToString();

textbox3.text= total in 3rd column


Plz help..URGENT..
Jquery and Javascript prefered..Plz.. because it will take so much time in load and add/edit/delete butons
