Hello

Say i have a textbox call val1 and combox that has three indexes (Meter,Feet,Inches). Say if initially user entered the value "1" in the texfield(val1) and selected "feet" from combobox. Now what i am not been able to solve is that say now suddenly he just selects inches from combobox, now i want the value in the textbox to be converted in inches(should be 12). I know the formula how to convert it :) but i donot know how to know what was the last selected value or may be if some one can guide me how this case can be solved.

Thanks anyways

Solution 2

simply do this create form level variable

C#

int FormLevelcmbbox1LastValue  = 0;

now in combox's selection value change

C#

cmbbox1_selectedValueChange(...)
{
	ConvertFrom = FormLevelcmbbox1LastValue ;
	ConvertTo = cmbbox1.selectedValue ;
	//write stuff to change value of textbox
	//set FormLevelcmbbox1LastValue
	FormLevelcmbbox1LastValue = cmbbox1.selectedValue ;
}

Happy Coding!
:)
