如果双击网格视图的行标题单元格,则会出现索引参数错误。我试着用RowIndex语句在双击事件中修复这个问题,但还有其他地方应该这样做吗?
private void DGV1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
try
{
if ((e.ColumnIndex > 0))
{
EditUser eu = new EditUser();
eu.UserId = DGV1.Rows[e.RowIndex].Cells[1].Value.ToString();
FormFunctions.OpenMdiDataForm(Program.GetMainMdiParent(), eu);
}
if (e.RowIndex == 0 || e.RowIndex == -1)
{
return;
}
}
catch (Exception ex)
{
MessageBox.Show("Errorn" + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
您的验证逻辑没有按所需顺序应用。将您的检查条件更改为以下内容:
try
{
if (e.ColumnIndex > 0 && e.RowIndex > 0)
{
EditUser eu = new EditUser();
eu.UserId = DGV1.Rows[e.RowIndex].Cells[1].Value.ToString();
FormFunctions.OpenMdiDataForm(Program.GetMainMdiParent(), eu);
}
}
catch (Exception ex)
{
MessageBox.Show("Errorn" + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
