DataGridViewComboBoxCell 默认显示行值
DataGridViewComboBoxCell show row value as default
我想在 DataGridView
中的任何行的特定列中放置一个 DataGridViewComboBoxCell
。
现在我遇到了问题...我想在我放置 DataGridViewComboBoxCell
的特定列中显示默认值,但没有显示任何内容..
String[] options = new String[] {"On", "Off" };
for(int i = 0; i< rows.Count; i++)
{
// lets say one row looks like this {"1","On"}, {"2", "Off"}
MydataGridView.Rows.Add(rows[i]);
DataGridViewComboBoxCell MyComboBox= new DataGridViewComboBoxCell();
MyComboBox.Items.AddRange(options);
MydataGridView.Rows[i].Cells[1] = MyComboBox;
}
我想默认显示我添加的行,然后才能通过 DataGridViewComboBoxCell
.
select {"On","Off"}
状态
我希望已经足够清楚了。 :)
这个呢(DataGridView.CellFormatting Event
):
public Form1()
{
InitializeComponent();
MydataGridView.CellFormatting += MydataGridView_CellFormatting;
}
private void MydataGridView_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (e.ColumnIndex == 1) //Index of your DataGridViewComboBoxCell
{
e.Value = "yourDefaultValue";
}
}
我也看到了以下事件,它也用于设置默认值 (DataGridView.DefaultValuesNeeded Event
):
public Form1()
{
InitializeComponent();
MydataGridView.DefaultValuesNeeded += MydataGridView_DefaultValuesNeeded;
}
private void MydataGridView_DefaultValuesNeeded(object sender, DataGridViewRowEventArgs e)
{
e.Row.Cells[1].Value = "yourDefaultValue";
}
