条件 DataGridView 格式 [英] Conditional DataGridView Formatting

问题描述

我有一个 DataGridView.我将它的 .DataSource 道具设置为我自己对象的 BindingList:一个 BindingList

I have a DataGridView. I set its .DataSource prop to be an BindingList of my own objects: a BindingList<IChessItem>

然后我为它创建了一些列..

I then created some columns for it..

    DataGridViewTextBoxColumn descColumn = new DataGridViewTextBoxColumn();
    descColumn.DataPropertyName = "Description";
    descColumn.HeaderText = "Description";
    descColumn.Width = 300;

    DataGridViewTextBoxColumn gameIDColumn = new DataGridViewTextBoxColumn();
    gameIDColumn.DataPropertyName = "GameID";
    gameIDColumn.HeaderText = "Game ID";
    gameIDColumn.Width = 60;

    dataGrid.Columns.Add(descColumn);
    dataGrid.Columns.Add(gameIDColumn);

我的问题是..我想根据 BindingList 的另一个字段中的数据将其中一个列着色为绿色).我该怎么做?

My question is.. I want to color one of the columns GREEN based upon data in another field of my BindingList). How can I do this?

我真的不需要显示这个字段，我只想对其中的数据采取行动..

I don't really have to show this field, I just want to act upon the data in it..

在我的例子中，IChessItem 的一个字段显示记录是否是新的，我想为 datagridview 中的其他字段着色以反映这一点.

in my case, one of the fields of IChessItem shows whether the record is new, and I want to color the other fields in the datagridview to reflect that.

推荐答案

您可以使用 DataGridView 的 'CellFormatting' 事件.DataGridViewCellFormattingEventArgs 包含当前单元格被绑定时的行和列的索引.我希望我的代码示例对您有意义:

You can use the 'CellFormatting' event of the DataGridView. The DataGridViewCellFormattingEventArgs contains indexes of the row and the column of the current cell as it is being bound. I hope my code example makes some sense to you:

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    // Compare the column to the column you want to format
    if (this.dataGridView1.Columns[e.ColumnIndex].Name == "ColumnName")
    {
        //get the IChessitem you are currently binding, using the index of the current row to access the datasource
        IChessItem item = sourceList[e.RowIndex];
        //check the condition
        if (item == condition)
        {
             e.CellStyle.BackColor = Color.Green;
        }
    }
}
