如何将用户输入的数据添加到DataGridView中？ [英] How do I add the data a user inputs into a DataGridView?

问题描述

我有一个DataGridView，它有1列。我希望用户添加他们需要的行数。然后，当他们移动到下一个选项卡时，将保存行。用户输入数据时可以移动到下一个选项卡，如果他们返回，数据仍然存在。但是，当我尝试在离开选项卡时保存数据时，DataGridView的行数为0.因此，不要输入foreach语句，我尝试从中获取单元格数据。



我尝试获取数据时的代码是 -

I have a DataGridView which has 1 column. I want the user to add as many rows they need. Then when they move onto the next tab the rows are saved. At the moment the user enters the data and can move to next tab and if they go back the data is still there. However when I try to save the data when they leave the tab, the row count for the DataGridView is 0. Therefore not entering the foreach statement where I try get the cell data from.

My code for when I try to get the data is-

foreach (DataRow row in gv_mullionList.Rows)
{
  //never gets this far
  //would set cell value to an object
}

为什么我需要做这些行？

Why do I need to do to get the rows?
