从另一个实例删除DataGridView行 [英] DataGridView row deleting from another instance

问题描述

你好，我有以下代码创建一个datagridview控件并将其放入tabcontroll的选项卡页，我的问题是我需要某种方式(最可能是使用事件处理程序(因为我一直需要获取实时信息)选定的行))，此数据网格视图中选定行中的值将在另一个按钮中使用.有人知道我该怎么做吗?

Hello,i have the following code that creates a datagridview control and put it into a tab page of a tabcontroll, my problem is that i need to get somehow (mostlikely with an event handler (because i need allways to get the realtime selected row)) a value from a selected row in this data grid view to be used in another button. Anyone know how can i do this?

private void button1_Click(object sender, EventArgs e)
        {
            tabControl1.TabPages.RemoveByKey("Database ImageTable");
            DataGridView datagrid1 = new DataGridView();
            Utile.Customtabpage.tabpage(tabControl1, datagrid1, "Database ImageTable");
            datagrid1.DataSource = Utile.DB.fillImgT(ConnectionSTR);
            datagrid1.BackgroundColor = Color.White;
            datagrid1.AllowUserToAddRows = false;
         
        }

推荐答案

你好

试试这个:

Hello

Try this:

private void button1_Click(object sender, EventArgs e)
        {
            tabControl1.TabPages.RemoveByKey("Database ImageTable");
            DataGridView datagrid1 = new DataGridView();

            datagrid1.SelectionChanged += new EventHandler(datagrid1_SelectionChanged);

            Utile.Customtabpage.tabpage(tabControl1, datagrid1, "Database ImageTable");
            datagrid1.DataSource = Utile.DB.fillImgT(ConnectionSTR);
            datagrid1.BackgroundColor = Color.White;
            datagrid1.AllowUserToAddRows = false;
         
        }

然后定义一个方法:

Then Define a Method:

void datagrid1_SelectionChanged(object sender, EventArgs e)
{
    var rows = ((DataGridView)sender).SelectedRows;

    if (rows.Count > 0)
    {
        //...
    }
}
