Karthi Keyan · Answer

hei goto your design track the button from tools and put where you want. and double click that button. the code page will open. in that private void button1_Click(object sender EventArgs e) { // place your code here. like this. int Qty = Convert.ToInt32(comboBoxunit. Text ); decimal Unit_Price = Convert.ToDecimal(qtytxtprice.Text); decimal Tax = Convert.ToDecimal(comboBoxtax. Text ); decimal TotalAmount = ( Qty * Unit_Price ); decimal PercentageAmount = (( Unit_Price * Tax ) / 100); TotalAmount = TotalAmount + PercentageAmount; } the button click will show like this. put your code in that.

Jyoti...this is going to sound too rude to you. However someone has to do it. With the kind of question you are asking you learning while coding. Nothing wrong with that. However if you do that with the help of forums like this it is not going to be very helpful to you. We will provide code in bits and pieces and you will implement it and it will work (may be!). But at the end of the day you will not know 'WHY you did it that way?' My suggestion whatever technology you have chosen (Windows Forms asp.net asp.net mvc) get a book in complete tutorial is given with code for building a fully working small application. Follow that code read the book. It will be faster and (in the end) better for you. Any question(s) please feel free to ask.

Text ); decimal TotalAmount = ( Qty * Unit_Price ); decimal PercentageAmount = (( Unit_Price * Tax ) / 100); TotalAmount = TotalAmount + PercentageAmount;

Jyoti Jodha · Answer

int Qty = Convert.ToInt32(txtqty.Text); // use combobox.Text to get value. decimal Unit_Price = Convert.ToDecimal(qtytxtprice.Text); decimal Tax = Convert.ToDecimal(txttax.Text); // use combobox.Text to get value. decimal TotalAmount = (txtqty * qtytxtprice); // here u didn't use .Text then how the value will pass in your field. (int.Parse(comboBoxunit.Text)* int.Parse(qtytxtprice.Text)).ToString; decimal PercentageAmount = ((qtytxtprice * txttax) / 100); // Same Issue. TotalAmount = TotalAmount + PercentageAmount;

Karthi Keyan · Answer

Jyoti Jodha · Answer

Red Line show in this code decimal TotalAmount = (txtqty * qtytxtprice); decimal PercentageAmount = (( qtytxtprice * txttax ) / 100);

Karthi Keyan · Answer

@jodha i modified something in your code. try this. int Qty = Convert.ToInt32(comboBoxunit. Text ); decimal Unit_Price = Convert.ToDecimal(qtytxtprice.Text); decimal Tax = Convert.ToDecimal(comboBoxtax. Text ); decimal TotalAmount = ( Qty * Unit_Price ); decimal PercentageAmount = (( Unit_Price * Tax ) / 100); TotalAmount = TotalAmount + PercentageAmount; Bug's in your code. int Qty = Convert.ToInt32(comboBoxunit.SelectedValue); // use combobox.Text to get value. decimal Unit_Price = Convert.ToDecimal(qtytxtprice.Text); decimal Tax = Convert.ToDecimal(comboBoxtax.SelectedValue); // use combobox.Text to get value. decimal TotalAmount = (comboBoxunit* qtytxtprice); // here u didn't use .Text then how the value will pass in your field. (int.Parse(comboBoxunit.Text)* int.Parse(qtytxtprice.Text)).ToString; decimal PercentageAmount = ((qtytxtprice * comboBoxtax) / 100); // Same Issue. TotalAmount = TotalAmount + PercentageAmount;
