DataGridView的单元格编辑结束事件 [英] DataGridView cell edit end event

问题描述

我有一个DataGridView中，我有一列'总'。 DataGridView的是可编辑的真实。网格视图下面我文本中，我网格的总计栏总希望。我所做的是，当用户进入电网的总列，它反映到贝洛奥里藏特的网格视图总文本字段。在文本框中显示总，我添加了网格视图总列。但问题是，如果我第一次进入到网格视图总列，它会立即反映到下面的文本框。但如果我编辑DataGridView中的总列的值相同，网格下的文本框与我想要的文本字段的编辑后的新价值previous值添加它。 ？如何解决这个问题下面是code： -

 私人无效grdCaret_CellEndEdit（对象发件人，DataGridViewCellEventArgs E）
{
    尝试
    {
        字符串值= grdCaret.Rows [e.RowIndex] .Cells [e.ColumnIndex] .Value.ToString（）;
        如果（e.ColumnIndex == 1）
        {
           // INT VAL = int.Parse（值）;
           //数量= VAL;
           // ekundag = ekundag +量;
           //tbTotDag_cr.Text = ekundag.ToString（）;

            INT量= 0;

            的foreach（的DataGridViewRow行grdCaret.Rows）
                量+ =（int）的grdCaret.Rows [e.RowIndex] .Cells [1] .Value.ToString（）;
                //量+ =（int）的row.Cells [1] .value的;

            tbTotDag_cr.Text = quantity.ToString（）;
        }

        如果（e.ColumnIndex == 2）
        {
            浮VAL = float.Parse（值）;
            总= VAL;
            ekunrakam = ekunrakam +总和;
            tbTotPrice_cr.Text = ekunrakam.ToString（）;
        }
        grdCaret.Columns [3] .ReadOnly = FALSE;
    }
    赶上（例外前）
    {
        的MessageBox.show（ex.Message.ToString（））;
    }
}
 

解决方案

使用 CellEndEdit 事件来更新你的总价值：

 私人无效dataGridView_CellEndEdit（对象发件人，DataGridViewCellEventArgs E）
{
    INT总= 0;

    的foreach（的DataGridViewRow行dataGridView.Rows）
        共有+ =（int）的row.Cells [columnTotal.Index] .value的;

    totalTextBox.Text = total.ToString（）;
}
 

I have a DataGridView in which i have a column 'total'. DataGridView is editable true. below the grid view i have textbox in which i want the total of the 'total' column of grid. What i did is, when user enters into the total column in grid, it reflects into the total text field belo the grid view. to display total in the textfield, i added the total column of grid view. But the problem is, if first time i enter into the total column of grid view, it immediately reflects into the textfield below. but if i edit the same value in total column of DataGridView, the textfield below the grid adds it with previous value where i want the new edited value in the textfield. How to fix this?Following is the code:-

private void grdCaret_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    try
    {  
        string value = grdCaret.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
        if (e.ColumnIndex == 1)
        {
           // int val = int.Parse(value);
           // quantity = val;
           // ekundag = ekundag + quantity;
           //tbTotDag_cr.Text =ekundag.ToString();

            int quantity = 0;

            foreach (DataGridViewRow row in grdCaret.Rows)
                quantity +=(int) grdCaret.Rows[e.RowIndex].Cells[1].Value.ToString();
                //quantity +=(int) row.Cells[1].Value;

            tbTotDag_cr.Text = quantity.ToString();
        }

        if (e.ColumnIndex == 2)
        {
            float val = float.Parse(value);
            total = val;
            ekunrakam = ekunrakam + total;
            tbTotPrice_cr.Text = ekunrakam.ToString();
        }
        grdCaret.Columns[3].ReadOnly = false;
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message.ToString());
    }
}

解决方案

Use CellEndEdit event to update your total value:

private void dataGridView_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    int total = 0;

    foreach (DataGridViewRow row in dataGridView.Rows)            
        total += (int)row.Cells[columnTotal.Index].Value;

    totalTextBox.Text = total.ToString();           
}
