Question

我想遍历 DevExpress.GridView.gridcontrol的特定（已知）列的每个单元格，根据特定的单元格值进行一些验证，截至目前我所尝试的如下 - -

for (int i = 0; i < gridView1.Columns.Count; i++)
{
     this.gridView1.Columns[i].AppearanceCell.BackColor = Color.Red;
}

使用上面的代码我可以循环遍历DevExpress.GridView.gridcontrol的每一列但无法遍历特定（第i列）列的每个单元格。希望你能理解我想说的话。请帮忙..在此先感谢.. !!

Answer 1

参考文献中有一些例子：

Validating rows

Conditional Style Formatting

GridView.RowStyle Event

GridView.RowCellStyle Event

一个简单的循环：

// iterate cells and compose a tab delimited string of cell values
for (int i = 0; i < m_gridView.RowCount; i++)
{
     int rowHandle = m_gridView.GetRowHandle(i);
     ...
}
// and
for(int i = 0; i < gridView1.DataRowCount; i++)
{
     //Do something here
}

看看： GridView.GetRowCellValue方法

最后，我通过使用RowCellStyle事件得到了答案，如下所示 -

private void gridView1_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
        {
            DevExpress.XtraGrid.Views.Grid.GridView View = sender as DevExpress.XtraGrid.Views.Grid.GridView;

            if (e.Column.FieldName == "XYZ")
            {               
                string strCellValue = View.GetRowCellDisplayText(e.RowHandle, View.Columns["XYZ"]);
                int inStockCol = e.RowHandle;
                if (!strCellValue.Equals("NA"))
                {
                    double dblCellValue = Convert.ToDouble(strCellValue);

                    if (dblCellValue < 0 || dblCellValue > 1000)
                    {
                        e.Appearance.BackColor = Color.Red;
                        e.Appearance.BackColor2 = Color.LightPink;                      

                    }
                    else
                    {
                        e.Appearance.BackColor = Color.Green;
                        e.Appearance.BackColor2 = Color.LightGreen;
                    }
                }

            }
}
