textbox数据绑定后自由移动.txt

常用c#知识库

1.定义
private DataSet ds2;
2.绑定
private void button9_Click(object sender, System.EventArgs e)
		{
		
			ds2=CreateDataSet2();
			textName.DataBindings.Add("Text",ds2,"Products.ProductName");
			textQuan.DataBindings.Add("Text",ds2,"Products.QuantityPerUnit");
			trackBar1.Minimum=0;
			trackBar1.Maximum=this.BindingContext[ds2,"Products"].Count-1;

		}
3.移动

		private void trackBar1_Scroll(object sender, System.EventArgs e)
		{
			this.BindingContext[ds2,"Products"].Position=trackBar1.Value;
		}
