一步一步教你使用AgileEAS.NET基础类库进行应用开发-WinForm应用篇-演示ORM对象与DataGridView的绑定技术-商品字典的另一个实现

编写绑定代码

voidLoadDictList()

{

currentDict=DALHelper.DALManager.CreateProduct();

dictList=DALHelper.DALManager.CreateProductList();

dictList.GetProductList(this.tbSearch.Text);

//两种方式都支持

this.dataGridView1.DataSource=dictList;

//this.dataGridView1.DataSource=dictList.Rows;

}

privatevoidbtnSearch_Click(objectsender,EventArgse)

{

this.LoadDictList();

}

privatevoidbtnPrint_Click(objectsender,EventArgse)

{

if(dictList==null)

{

MessageBox.Show("没有需要打印的数据!","提?示?",MessageBoxButtons.OK,MessageBoxIcon.Information);

return;

}

if(this.printForm==null)

this.printForm=newPrintViewDialog();

//

System.IO.TextReadertextReader=null;

try

{

stringfileName=Path.Combine(Application.StartupPath,"Reports\\商品字典.rdl");

textReader=newSystem.IO.StreamReader(fileName);

this.printForm.SourceRdl=textReader.ReadToEnd();

}

finally

{

if(textReader!=null)

textReader.Close();

}

this.printForm.DataObject=dictList;

this.printForm.PrintPreview();

}

privatevoiddataGridView1_CellBeginEdit(objectsender,DataGridViewCellCancelEventArgse)

{

if(this.dataGridView1.CurrentRow!=null)

{

IProductproduct=this.dataGridView1.CurrentRow.DataBoundItemasIProduct;

currentDict.Code=product.Code;

}

}

privatevoiddataGridView1_CellEndEdit(objectsender,DataGridViewCellEventArgse)

{

IProductproduct=this.dataGridView1.CurrentRow.DataBoundItemasIProduct;

if(product.Code==currentDict.Code)

product.Update();

else

{

product.Update();

product.Idn=product.GetMaxNewIdn();

currentDict.Delete();

product.Insert();

}

}
