Question

我的查询是

SELECT  
    deldate,
    transno,
    matno,
    MAT_NAME,
    rawpkgno,
    MAX(SWITCH(deldate=? ,ORDCASES )) AS [CURRDATE],
    MAX(SWITCH(deldate=? ,ORDCASES )) AS [previous_day],
    MAX(SWITCH(deldate=? ,ORDCASES )) AS [Last_date]
FROM 
    invorder
WHERE
    invorder.strno =54009
    OR [invorder.deldate] IS NULL
GROUP BY
    matno,
    MAT_NAME,
    rawpkgno,
    transno,
    deldate

我想从gridview编辑它。由于这是视图，我无法从gridview编辑它。但是他们可以通过previous_day，Last_date列保持不变，而且我只能对CURRDATE列进行更改。请帮助我。

嗨，你必须在网格上绑定row_added事件，并且除了你想要编辑之外，所有单元格都是只读的。检查下面的代码..

    public Form1()
    {
        InitializeComponent();
        dataGridView1.RowsAdded += new DataGridViewRowsAddedEventHandler(dataGridView1_RowsAdded);  
    }

    void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
    {
        foreach (DataGridViewCell item in dataGridView1.Rows[e.RowIndex].Cells)
        {
            // here i used the 5 because i want to make the 5th index cell as editable.
            if (item.ColumnIndex == 5)
            {
                continue;
            }
            item.ReadOnly = true;
        }            
    }

    private void Form1_Load(object sender, EventArgs e)
    {            
        dataGridView1.DataSource = bind_your_data_source_here;
        dataGridView1.Refresh();
    }
