更新列表框，如果它有来自组合框的值，则插入到组合框中 [英] update listbox if it have value from combobox else insert in to combobox

问题描述

我有3个comboBox和3个ListBox

1个comboBox是项目代码

2 comboBox是信用

3 comboBox是debit



并且它在3个单独的列表框中插入值。



i当我将值插入到列表框中时组合框它必须只插入带有信用卡和借记卡的新商品代码。

如果项目代码在列表框中存在，则必须更新该商品代码的信用卡和借记卡。

i have 3 comboBox and 3 ListBox
1 comboBox is item code
2 comboBox is credit
3 comboBox is debit

and it is inserting values in its 3 individual listboxs.

i want when i insert value in to list boxes from comboboxes it must only insert new itemcode with credit and debit.
if item code exsist in the listbox alredy then it must update that itemcode''s credit and debit.

推荐答案

像这样......

Something like this ...

int index = listItemCode.Items.IndexOf(cbItemCode.Text);
if( index >= 0 )
{
	//Amend the corresponding entries in the other list boxes
	listCredit.Items[index] = cbCredit.Text;
	listDebit.Items[index] = cbDebit.Text;
}
else
{
	//Add this as a new item
	listItemCode.Items.Add(cbItemCode.Text)
	listCredit.Items.Add(cbCredit.Text);
	listDebit.Items.Add(cbDebit.Text);
}
