单击标题时，Datagridview崩溃。 [英] Datagridview crashes when header is clicked.

问题描述

如果我点击datagridview的标题，它会崩溃。我不知道如何解决它。我收到此错误：



mscorlib.dll中发生System.ArgumentOutOfRangeException类型的未处理异常



补充信息：指数超出范围。必须是非负数且小于集合的大小。



此时崩溃：

  private   void  dgvProfiles_CellClick（ object  sender ，DataGridViewCellEventArgs e）
 {indexRow = e.RowIndex;  //  获取所选行索引 
 DataGridViewRow row = dgvProfiles.Rows  [indexRow ];  
} 

我的尝试：



我试图编辑DataGridViewRow row = dgvProfiles.Rows [indexRow]，但似乎没什么用。

If I click the header of my datagridview, it crashes. I have no idea how to fix it. I am getting this error:

An unhandled exception of type System.ArgumentOutOfRangeException occurred in mscorlib.dll

Additional information: Index was out of range. Must be non-negative and less than the size of the collection.

It's crashing at this point:

private void dgvProfiles_CellClick(object sender, DataGridViewCellEventArgs e)
        {   indexRow = e.RowIndex; // get the selected Row Index
            DataGridViewRow row = dgvProfiles.Rows[indexRow];
