数据网格视图选择单元格值如何获取它 [英] Data grid view selected cell value how to get it

问题描述

我想在Click事件中选择DataGridView Cell值我使用此代码会产生错误

i Want to get DataGridView selected Cell value on click event i use this code its generates a error

DataGridViewRow dgvrows = TrGrid.SelectedRows;
string c = dgvrows.Cells("Late_Time").value.toString();

推荐答案

DataGridView有一个< a href =http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.currentcell(v=vs.80).aspx> CurrentCell属性 [ ^ 。我认为这就是选定单元格的含义。如果你想查看所有选中的单元格，它有一个可枚举的SelectedCells属性来给出单元格对象。

DataGridView has a CurrentCell property[^]. I think that is what you mean by 'selected cell'. If you want to look at all the selected cells, it has a SelectedCells property which is enumerable to give cell objects.

下面这段代码可以帮到你：

The following piece of code will do the trick for you:

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value != null)
    {
       MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString());
    }
}

希望这能帮到你。

Hope this will help you out.

SelectedRows 将返回 DataGridViewSelectedRowCollection 类型的行集合，而不是 DataGridViewRow 。



所以你可以像这样使用它：

SelectedRows will return a collection of rows of type DataGridViewSelectedRowCollection and not DataGridViewRow.

So you can use it like this :

DataGridViewSelectedRowCollection rows = dataGridView1.SelectedRows;
string val =(string)rows[2].Cells["Late_Time"].Value; //I have specified rowIndex as 2 as an example
