datagridview中基于不同列值的数字格式 [英] Number format in datagridview based on different columns value

问题描述

我在VS 2008工作。我有一个数据网格视图，其中有一列显示带小数的数字。第二列名称为Decimals。我需要根据Decimals列中的内容设置第一列的数字小数。示例编号为10.00000，小数为3.现在，编号列必须为10.000。我希望这是有道理的。我希望我可以在数据网格视图的编辑列的格式属性中执行此操作。我不是那么请帮我解释一下代码。从来没有这样做过。



我尝试过：



我试图把它放在数据网格视图的编辑列中，如N {Decimals.Value}位，它将Decimals1Value放在单元格中。我在代码中试了但是卡在这里。

Hi, I am working in VS 2008. I have a data grid view that have a column displaying numbers with decimals. A second column name Decimals. I need to set the first column's number decimals based on what is in the Decimals column. Example Number is 10.00000 and Decimals is 3. Now the Number column must b 10.000. I hope this makes sense. I hope I can do this in the data grid view's edit columns' format properties. I not then please help me with the code. Never done this before.

What I have tried:

I tried to put it in the data grid view's edit columns like N{Decimals.Value} bit it put Decimals1Value in the cell. I tried it in code but got stuck here.
