使用C#在Windows窗体中将项目从一个CheckedListBox添加到另一个CheckedListBox. [英] Adding Items from one CheckedListBox to another CheckedListBox in Windows Form using C#.
问题描述
我有两个CheckedListBox 1)chkLstVendor& 2)chkLstVendorAdded和一个添加按钮btn_Add.
I have two CheckedListBox 1) chkLstVendor & 2) chkLstVendorAdded and a Add button btn_Add.
当我检查chkLstVendor中的某些项目并按添加"按钮时，选中的项目将转到chkLstVendorAdded，并且这些项目将从chkLstVendor中删除.
When I check some items in chkLstVendor and press the Add button the checked items will go to chkLstVendorAdded and the items will be removed from chkLstVendor.
我编写的代码如下:
-填充代码 chkLstVendor和 chkLstVendorAdded
公共数据表dtVendor；
public DataTable dtVendor;
公共数据表dtAdd;
public DataTable dtAdd;
DataView dv1;
DataView dv1;
DataView dv2;
DataView dv2;
公共无效frm_Load(.......)
public void frm_Load(.......)
{
CreateTable();
CreateTable();
PopulateVendor();
PopulateVendor();
PopulateVendorAdd();
PopulateVendorAdd();
}
私有无效PopulateVendor()
private void PopulateVendor()
{
dtVendor = DBCon.Result("....."); //DBCon是连接dll.
dtVendor=DBCon.Result("....."); // DBCon is connection dll.
dv1 =新的DataView(dtVendor);
dv1=new DataView(dtVendor);
chkLstVendor .DataSource = dv1;
chkLstVendor .DataSource=dv1;
chkLstVendor.DisplayMember ="VendorName";
chkLstVendor.DisplayMember="VendorName";
chkLstVendor.ValueMember ="VendorID";
chkLstVendor.ValueMember="VendorID";
}
私有无效CreateTable()
private void CreateTable()
{
//在这里，我向dtAdd类型的Int(VendorID)和String(VendorName)添加了两行
//Here I am adding two rows to the dtAdd of type Int(VendorID) and String(VendorName)
}
private void&PopulateVendorAdd()
private void PopulateVendorAdd()
{
dv2 =新的DataView(dtAdd);
dv2=new DataView(dtAdd);
chkLstVendorAdd.DataSource = dv2;
chkLstVendorAdd.DataSource=dv2;
chkLstVendorAdd.DisplayMember ="VendorName";
chkLstVendorAdd.DisplayMember="VendorName";
chkLstVendorAdd.ValueMember ="VendorID";
chkLstVendorAdd.ValueMember="VendorID";
}
private void btn_Add_Click(对象发送者，EventArgs e)
private void btn_Add_Click(object sender, EventArgs e)
{
DataRow rows = new DataRow();
DataRow rows=new DataRow();
dtAdd.NewRow();
dtAdd.NewRow();
for(int i = 0; i< chkLstVendor.CheckedItems.Count; i ++)
for(int i = 0; i < chkLstVendor.CheckedItems.Count; i++)
{
DataRow row =(DataRow)((DataRowView)chkLstVendor.CheckedItems [i]).Rows;
DataRow row=(DataRow)((DataRowView)chkLstVendor.CheckedItems[i]).Rows;
rows [0] = row ["VendorID"];
rows[0]=row["VendorID"];
rows [1] = row ["VendorName"];
rows[1]=row["VendorName"];
dtAdd.AddRows(rows);
dtAdd.AddRows(rows);
}
//将chkLstVendor的已检查项目添加到chkLstVendorAdd的这一部分工作正常.
// This part of adding the checked items from chkLstVendor to chkLstVendorAdd is working fine.
//但现在我不得不从chkLstVendor中删除选中的项目.我写的代码只是删除
//But now I am stuck in removing the checked items from chkLstVendor. The code that I have written is only removing
//一项.
for(int i = 0; i< chkLstVendor.CheckedItems.Count; i ++)
for(int i = 0; i < chkLstVendor.CheckedItems.Count; i++)
{
DataRow row =(DataRow)((DataRowView)chkLstVendor.CheckedItems [i]).Rows;
DataRow row=(DataRow)((DataRowView)chkLstVendor.CheckedItems[i]).Rows;
int id = Convert.toInt32(row ["VendorID"].toString());
int id=Convert.toInt32(row["VendorID"].toString());
DataRow [] rows = dtVendor.Select("VendorID =" + a);
DataRow[] rows=dtVendor.Select("VendorID=" +a);
foreach(行中的DataRow rw)
foreach(DataRow rw in rows)
{
rw.Delete();
rw.Delete();
}
}
chkLstVendor.Refresh();
chkLstVendor.Refresh();
chkLstVendorAdd.Refresh();
chkLstVendorAdd.Refresh();
//现在此代码仅删除一个条目，即假设我已经检查了两个项目并按下了添加按钮
// Now this code is only deleting one entry, i.e. supposed I have checked two items and pressed the Add button
//chkLstVendor填充了两个选中的项，但是仅删除了一个选中的项
// the chkLstVendor is populated with both the checked items, but only one checked item is deleted
// chkLstVendor
// from chkLstVendor
//我尝试使用DataView.RowFilter属性，但无法正确执行.
}
请帮助.我处于一个非常绝望的情况.预先感谢.

推荐答案
尝试如下更改for语句:
Try changing the for statement as follows:
for(int i = 1; i< = chkLstVendor.CheckedItems.Count; i ++)
for(int i = 1; i <= chkLstVendor.CheckedItems.Count; i++)
看看是否有帮助.
