为什么我不能看到的DataGridViewRow添加到一个DataGridView？ [英] Why can't I see the DataGridViewRow added to a DataGridView?

问题描述

我想显示行一个DataGridView。

这里的code：

 的foreach（客户卡斯特在CUSTLIST）
            {
                字符串[] rowValues​​ = {cust.Name，cust.PhoneNo};
                的DataGridViewRow行=新的DataGridViewRow（）;
                布尔行集= row.SetValues​​（rowValues​​）;
                row.Tag = cust.CustomerId;
                dataGridView1.Rows.Add（行）;
            }
 

在窗体加载，我已经初始化dataGridView1的是：

  dataGridView1.ColumnCount = 2;
dataGridView1.Columns [0] .Name点=名称;
dataGridView1.Columns [1]，请将.Name =电话;
 

在执行该code，四值得注意的事情发生了：

• 我可以看到dataGridView1的创建一个新的行。
• 有没有在它的文字。
• 行集是假执行row.SetValues​​方法之后。
• 在该行标记值是否设置正确。

为什么没有在DataGridView显示的数据？

解决方案

 名单，其中，客户＆GT; CUSTLIST = GetAllCustomers（）;
            dataGridView1.Rows.Clear（）;

            的foreach（在CUSTLIST客户CUST）
            {
                //首先增加了该行，因为那是它是如何工作！不知道为什么！
                的DataGridViewRow R = dataGridView1.Rows [dataGridView1.Rows.Add（）];
                //然后编辑
                R.Cells [名称]值= cust.Name。
                。R.Cells [地址]值= cust.Address;
                。R.Cells [电话]值= cust.PhoneNo;
                //客户ID是无形的，但仍然可用，比如，
                //当双单击显示的全部细节
                R.Tag = cust.IntCustomerId;
            }

I am trying to show rows in a DataGridView.

Here's the code:

foreach (Customers cust in custList)
            {
                string[] rowValues = { cust.Name, cust.PhoneNo };
                DataGridViewRow row = new DataGridViewRow();
                bool rowset = row.SetValues(rowValues);
                row.Tag = cust.CustomerId;
                dataGridView1.Rows.Add(row);
            }

On form load, I have initialized dataGridView1 as:

dataGridView1.ColumnCount = 2;
dataGridView1.Columns[0].Name = "Name";
dataGridView1.Columns[1].Name = "Phone";

After this code is executed, four notable things happen:

• I can see a new row created in the dataGridView1.
• There's no text in it.
• rowset is false after row.SetValues method is executed.
• The row tag value is set correctly.

Why doesn't the DataGridView show data?

解决方案

List<customer> custList = GetAllCustomers();
            dataGridView1.Rows.Clear();

            foreach (Customer cust in custList)
            {
                //First add the row, cos this is how it works! Dont know why!
                DataGridViewRow R = dataGridView1.Rows[dataGridView1.Rows.Add()];
                //Then edit it
                R.Cells["Name"].Value = cust.Name;
                R.Cells["Address"].Value = cust.Address;
                R.Cells["Phone"].Value = cust.PhoneNo;
                //Customer Id is invisible but still usable, like,
                //when double clicked to show full details
                R.Tag = cust.IntCustomerId;
            }
