comboBox1_SelectedIndexChanged事件


如上图：radiobutton_checkedchanged事件与comboBox1_SelectedIndexChanged事件，相结合

C# code

private void radioButton318_CheckedChanged(object sender, EventArgs e)        {            if (tmpRadio != null)            {                tmpRadio.Checked = false;            }            tmpRadio = (sender as RadioButton);            if (radioButton318.Checked)            {               clsGridStyle.rdo318();               clsCellCompute.rdo318();                               List.OwnerDrawCell += new FlexCell.Grid.OwnerDrawCellEventHandler(clsDrawBrokenline.rdo318);               List.OwnerDrawCell += new FlexCell.Grid.OwnerDrawCellEventHandler(clsDrawImage.rdo318);            }            else            {                List.OwnerDrawCell -= new FlexCell.Grid.OwnerDrawCellEventHandler(clsDrawBrokenline.rdo318);                List.OwnerDrawCell -= new FlexCell.Grid.OwnerDrawCellEventHandler(clsDrawImage.rdo318);             }        }

F5调试的时候，执行上面的代码,进行关于“7”的查询
触发comboBox1_SelectedIndexChanged后
radioButton318 处于unchecked状态，怎么回事呢？

C# code

 private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)        {            //        }

comboBox1_SelectedIndexChanged事件里的代码该如何写呢？谢谢

[解决办法]
你这代码根本就不对。

List.OwnerDrawCell -= new FlexCell.Grid.OwnerDrawCellEventHandler(clsDrawBrokenline.rdo318);
根本就不能移除你之前添加的事件处理函数。
