为什么不执行呀

[chengciukui]

Combox　SelectValueChanged事件
private void ComboxSelectValueChanged_Click(object sender, EventArgs e)
{
try
{
Cursor = Cursors.WaitCursor;
//String sqlStr = "select ContractNo from Contract " +
// "where ClientNo='" + this.CustomeNortextBox3.Text + "'and ContractType='" + this.comboBox3.Text + "'";

String sqlStr = "select ContractNo from Contract " +
"where ClientNo='" + this.CustomeNortextBox3.Text.Trim() + "'";
DataSet userDataset = bussiness.ExecuteDetset(sqlStr);
　　　　　　　　下面的代码怎么不执行呀，郁闷
this.ContractComboBox5.DataSource = userDataset.Tables[0];
this.ContractComboBox5.DisplayMember = "ContractNo";
this.ContractComboBox5.ValueMember = "ContractNo";
this.ContractComboBox5.SelectedValue = 1;



}
catch (Exception ex)
{
DisplayErrors(ex);
}
finally
{
Cursor = Cursors.Arrow;
}

bussiness 呢？？

[易企加_天马行空]

你凭什么说没执行呢？debug跟踪了？

[chenyanm]

调试一下不就知道了吗

[zhantianyou]

看不出什么原因,是不是bus..那里出錯啊.

[flythere]

this.ContractComboBox5.DataSource = userDataset.Tables[0];
this.ContractComboBox5.DisplayMember = "ContractNo";
this.ContractComboBox5.ValueMember = "ContractNo";
加上下面这句：
this.ContractComboBox5.DataBind();
