为什么在页面上没有显示DataGrid控件?????????郁闷

[Qinglei]

要具体代码

[Qinglei]

这是数据绑定部分
DataColumn yeWuType = new DataColumn();
yeWuType.DataType = System.Type.GetType("System.String");
yeWuType.ColumnName="yeWuType";//业务种类
contentTable.Columns.Add(yeWuType);

DataColumn dianLuType = new DataColumn();
dianLuType.DataType = System.Type.GetType("System.String");
dianLuType.ColumnName="dianLuType";//业务种类
contentTable.Columns.Add(dianLuType);

DataColumn dianLuAttri = new DataColumn();
dianLuAttri.DataType = System.Type.GetType("System.String");
dianLuAttri.ColumnName="dianLuAttri";//电路性质
contentTable.Columns.Add(dianLuAttri);

DataColumn dianLuSpeed = new DataColumn();
dianLuSpeed.DataType = System.Type.GetType("System.String");
dianLuSpeed.ColumnName="dianLuSpeed";//电路速率
contentTable.Columns.Add(dianLuSpeed);

DataColumn hireAmount = new DataColumn();
hireAmount.DataType = System.Type.GetType("System.String");
hireAmount.ColumnName="hireAmount";//租用数量
contentTable.Columns.Add(hireAmount);

DataColumn monthRate = new DataColumn();
monthRate.DataType = System.Type.GetType("System.String");
monthRate.ColumnName="monthRate";//月租费
contentTable.Columns.Add(monthRate);

DataColumn favourRate = new DataColumn();
favourRate.DataType = System.Type.GetType("System.String");
favourRate.ColumnName="favourRate";//优惠率
contentTable.Columns.Add(favourRate);

DataColumn yearRate = new DataColumn();
yearRate.DataType = System.Type.GetType("System.String");
yearRate.ColumnName="yearRate";//年租费
contentTable.Columns.Add(yearRate);

DataColumn startTime = new DataColumn();
startTime .DataType = System.Type.GetType("System.String");
startTime .ColumnName="startTime";//开通时间
contentTable.Columns.Add(startTime);

dataSet.Tables.Add(contentTable);

for( int i=1;i<=5;i++)
{
DataRow myDataRow = contentTable.NewRow();
myDataRow["yeWuType"]="";
myDataRow["dianLuType"]="";
myDataRow["dianLuAttri"]="";
myDataRow["dianLuSpeed"]="";
myDataRow["hireAmount"]="";
myDataRow["monthRate"] = "0";
myDataRow["favourRate"]="";
myDataRow["yearRate"]="";
myDataRow["startTime"]="";
contentTable.Rows.Add(myDataRow);
}
}
public void DataGridDataBind()
{
InitializeDataSet();

try
{
editDataGrid.DataSource = dataSet.Tables["contentTable"];
editDataGrid.DataBind();
}
catch(Exception ex)
{
Response.Write(ex.ToString());
}
}

[smallfools]

将
editDataGrid.DataSource = dataSet.Tables["contentTable"];
改为
editDataGrid.DataSource = dataSet.Tables["contentTable"].DefaultView;

这样绑定才有用。

还有一个问题啊啊.你知道怎么让一个dropdownlist1选择后,另外的一个dropdownlist2也改变,但是
dropdownlist1要保留选择的东西

[游戏Lan]

飞思的.net与web数据库一书中有个很详细的例子
就是关于dropdownlist的

[Qinglei]

好的
谢谢

[WZCNet]

在DropDownList1的SelectIndexChange事件中写，如果DropDownList2中的数据已读出到了DataTable中，你可以用DataView的筛选功能，选出与DropDownList1相对应的项，绑定到DropDownList中。
