删除DGV中的选定行C＃(Delete Selected Row in DGV C#)

删除DGV中的选定行C＃(Delete Selected Row in DGV C#)

我的问题是：

我想从所选行中检索数据（row.Cells [4] .Value），然后在变量中分配它。 获取数据后，我想使用按钮删除选定的行。

这是我的代码：

private void btnDelete_Click(object sender, EventArgs e) { if (dataGridViewPOS.SelectedRows.Count > 0) { string qty = row.Cells[4].Value; dataGridViewPOS.Rows.Remove(dataGridViewPOS.SelectedRows[0]); } }

My Problem is:

I want to retrieve the data(row.Cells[4].Value) from the selected row then assign it in a variable. After getting the data I want to delete the selected row using a button.

Here is my code:

private void btnDelete_Click(object sender, EventArgs e) { if (dataGridViewPOS.SelectedRows.Count > 0) { string qty = row.Cells[4].Value; dataGridViewPOS.Rows.Remove(dataGridViewPOS.SelectedRows[0]); } }

最满意答案

你的代码的问题是你没有定义row变量。

尝试：

if (dataGridViewPOS.SelectedRows.Count > 0) { var row = dataGridViewPOS.SelectedRows[0]; string qty = row.Cells[4].Value; dataGridViewPOS.Rows.Remove(dataGridViewPOS.SelectedRows[0]); }

这只是Alex评论的答案，我在回答后意识到了。

The problem with your code is that you haven't defined the row variable.

Try:

if (dataGridViewPOS.SelectedRows.Count > 0) { var row = dataGridViewPOS.SelectedRows[0]; string qty = row.Cells[4].Value; dataGridViewPOS.Rows.Remove(dataGridViewPOS.SelectedRows[0]); }

This is just an answer-version of Alex's comment, I realized it after answering.
