C＃如何从datagridview中删除项目（当前项目无法从列表中删除，因为没有当前项目） [英] C# how to delete item from datagridview (current item cannot be removed from the list because there is no current item)

问题描述

我在datagridview中有拒绝按钮喜欢这个 [ ^ ]



当我选择一行并点击时那个按钮，那行必须从datagridview中删除，但出了点问题，它给了我错误。当前项目无法从列表中删除，因为没有当前项目。问题是什么？



我尝试过：

I have Reject button in datagridview Like this[^]

When i select anr row and click on that button, that row must remove from datagridview,but something went wrong,it gives me error` Current item cannot be removed from the list because there is no current item.What's the problem?

What I have tried:

private void dataGridView2_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            
            if (dataGridView2.Columns[e.ColumnIndex].Name == "Reject")
            {
                if(MessageBox.Show("Are you sure that you want to reject this bid?","Message",MessageBoxButtons.YesNo,MessageBoxIcon.Question) == DialogResult.Yes)
                creditRequestsBindingSource.RemoveCurrent();
            }
            
        }

推荐答案

问题是当你单击一行中的按钮时，直到处理完按钮点击后才选择该行。



如果是我，我会在网格外部创建一个按钮，只在选择了一个网格行。

The problem is when you click a button in a row, the row isn't selected until after the button click is handled.

If it were me, I'd create a button external of the grid and only enable it when a grid row is selected.
