ComboBox的奇怪问题，路过有分，在线结贴
SWJGComboBox.DataBindings.Add(new System.Windows.Forms.Binding( "SelectedValue ", this.sb_zsxxBindingSource, "nsr_swjg_dm ", true));
this.dM_SWJGComboBox.DataSource = this.dM_SWJGBindingSource;
this.dM_SWJGComboBox.DisplayMember = "SWJG_JC ";
this.dM_SWJGComboBox.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList;
this.dM_SWJGComboBox.ValueMember = "SWJG_DM ";

private void dM_SWJGComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
this.dataSet1.sb_zsxx.Rows[BindingSource1.Position][ "SWJG_MC "] = dM_SWJGComboBox.Text;

}

以上为代码，奇怪的是下拉列表只能显示第一项，别的项目显示不出来。
而去掉this.dataSet1.sb_zsxx.Rows[BindingSource1.Position][0] = ComboBox1.Text
这句下拉列表就能正常显示，真是太奇怪了，是我的机器有问题，还是这个控件有BUG，还是代码有问题呢？

SWJG=守卫剑阁？不是吧？
[解决办法]
参考下面的绑定方式．
ComboBox1.DataSource = myDataSet ;//数据集
ComboBox1.DisplayMember = "person.userId " ;//表名加字段名
ComboBox1.ValueMember = "person.username " ;

this.ComboBox1.DataSource = myDataTable;//数据表
this.ComboBox1.DisplayMember = "Name ";//字段名
this.ComboBox1.ValueMember = "userId ";//字段名

//也许是这样
this.dataSet1.sb_zsxx.Rows[BindingSource1.Position][ "SWJG_MC "] = dM_SWJGComboBox.SelectedItem.ToString();
