关于DataGridView设置DispalyIndex后显示顺序不正确问题
编辑器vs2005
测试程序：
winform程序界面上已经存在一个DataGridView控件dataGridView1
public Form1()
{
InitializeComponent();
dataGridView1.DataSource = CreateTestTable();
SetColumnsOrder(dataGridView1);
}
private void SetColumnsOrder(DataGridView dgv)
{
dataGridView1.Columns[ "AccountID "].DisplayIndex = 0;
dataGridView1.Columns[ "RelationItemTypeID "].DisplayIndex = 1;
dataGridView1.Columns[ "RelationItemID "].DisplayIndex = 2;
dataGridView1.Columns[ "OperationDate "].DisplayIndex = 3;
dataGridView1.Columns[ "CreateDate "].DisplayIndex = 4;
dataGridView1.Columns[ "OperationValue "].DisplayIndex = 5;
dataGridView1.Columns[ "Remark "].DisplayIndex = 6;
dataGridView1.Columns[ "LastChangeTime "].DisplayIndex = 7;
dataGridView1.Columns[ "ID "].DisplayIndex = 8;
dataGridView1.Columns[ "BusinessTableCode "].DisplayIndex = 9;
}
//这是测试
private DataTable CreateTestTable()
{
DataTable dt = new DataTable();
DataColumn colID = new DataColumn( "ID ");
DataColumn colOperationValue = new DataColumn( "OperationValue ");
DataColumn colOperationDate = new DataColumn( "OperationDate ");
DataColumn colCreateDate = new DataColumn( "CreateDate ");
DataColumn colLastChangeTime = new DataColumn( "LastChangeTime ");
DataColumn colRemark = new DataColumn( "Remark ");
DataColumn colBusinessTableCode = new DataColumn( "BusinessTableCode ");
DataColumn colRelationItemTypeID = new DataColumn( "RelationItemTypeID ");
DataColumn colRelationItemID = new DataColumn( "RelationItemID ");
DataColumn colAccountID = new DataColumn( "AccountID ");
dt.Columns.AddRange(new DataColumn[] { colID, colOperationValue, colOperationDate, colCreateDate, colLastChangeTime
, colRemark,colBusinessTableCode,colRelationItemTypeID,colRelationItemID,colAccountID});
return dt;
}
在构造函数Form1()中设置DataGridView的显示列顺序时，显示的顺序与DisplayIndex属性设置的不一致。
希望的顺序：
AccountID
RelationItemTypeID
RelationItemID
OperationDate
CreateDate
OperationValue
Remark
LastChangeTime
ID
BusinessTableCode
而实际显示的顺序为：
AccountID
ID
RelationItemTypeID
RelationItemID
OperationValue
OperationDate
CreateDate
LastChangeTime
Remark
BusinessTableCode
不信在你的机器上试试。
如果把
dataGridView1.DataSource = CreateTestTable();
SetColumnsOrder(dataGridView1);
写到Form_Load()中或按扭事件中显示的顺序正确。
请高手帮忙分析分析，谢谢。
[解决办法]
不要在构造函数中做，这是可能dataGridView1还没有完全加载
[解决办法]
dataGridView2.DataSource = CreateTestTable();
SetColumnsOrder(dataGridView2);
放到form_Load中就ok了
[解决办法]
位置放错了， 变量好想也放错了吧
[解决办法]
具体为什么偶也说不好

来晚了，来接分吧
