如何在没有sql数据源的情况下将文本框数据绑定到数据网格视图中 [英] How to bind text boxes data in to Data grid view without sql data source

问题描述

大家好，



我在Windows窗体上创建了以下控件。



TextBox - txtName

按钮 - btnAdd

DataGridView - gvTotalNames



当我点击btnAdd按钮时，txtName文本应为插入到网格视图中。



再次在txtName中输入一些数据应该在网格视图中显示另外一条记录。



如何实现这个目标？



我可以看到结果如



姓名



aaaa

bbbb

cccc

dddd

Hi All,

I created on windows form with following controls.

TextBox - txtName
Button - btnAdd
DataGridView - gvTotalNames

When I click "btnAdd" button the txtName text should be inserted in to grid view.

Again entered some data into the txtName one more record should be displayed in to grid view.

How can I achieve this?

I can see the result like

Name

aaaa
bbbb
cccc
dddd

推荐答案

如果您的项目在vb.net中，那么使用此代码，如果C＃然后将此代码转换为C＃

if your project is in vb.net then use this code else if C# then convert this code to C#

Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
        gvTotalNames.Rows.Add()
        gvTotalNames.Item(0, gvTotalNames.Rows.Count - 1).Value = txtName.Text
        txtName.Text = ""
    End Sub
 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        gvTotalNames.AllowUserToAddRows = False
        gvTotalNames.Rows.Clear()       
    End Sub

private DataTable dt;
private void Form1_Load(object sender, EventArgs e)
{

    dt = new DataTable("TotalNames");
    DataColumn dc = new DataColumn("Names");
    dt.Columns.Add(dc);
    gvTotalNames.DataSource = dt;
}

private void btnAdd_Click(object sender, EventArgs e)
{
    DataRow dr = dt.NewRow();
    dr["Names"] = txtName.Text;
    dt.Rows.Add(dr);
}

因为你没有提供足够的细节，我会告诉你如何实现这个......



您可以通过多种方式实现这一目标，例如：

1）使用 DataTable [ ^ ]，

2）使用列表（T） [ ArrayList [ ^ ]

Because you did not provide enough details, i''ll show you a ways to achieve that...

You can do it in many ways, for example:
1) using DataTable[^],
2) using List(T)[^] generic class,
3) using ArrayList[^]
