我在page.aspx中有一个Gridview。这个gridview我想作为参数传递给class1.cs.Can的构造函数任何人都可以打电话给我,如何做到这一点?
答案 0 :(得分:1)
所以你有一个带有Gridview的页面:
<asp:GridView runat="server" ID="gv1" AutoGenerateColumns="true">
</asp:GridView>
<div>
This is where the count of rows of your GridView will be displayed:
<p>
<strong><asp:Label runat="server" ID="lCount" /></strong>
</p>
</div>
并且,在代码隐藏中,您可以像这样填充它:
this.gv1.DataSource = FullName.GetDemoCollection(); //Just returns a List<string>;
gv1.DataBind();
你有另一个类GridViewRowCounter
可以用GridView做一些事情,例如计算行数:
public class GridViewRowCounter
{
private System.Web.UI.WebControls.GridView _gv;
public GridViewRowCounter(){}
public GridViewRowCounter(System.Web.UI.WebControls.GridView _GV){
this._gv = _GV;
}
public int GetRowCount(){
return _gv.Rows.Count;
}
}
因此,要将GridView传递给Gridviewcounter类,您可以执行以下操作:
public partial class PassingControls : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//Bind the GridView
this.gv1.DataSource = FullName.GetDemoCollection();//
gv1.DataBind();
//Pass Gridview reference to the GridVeiwRowCounter constructor.
GridViewRowCounter gvcounter = new GridViewRowCounter(this.gv1);
//Get the external class to return the rowcount from your GridView.
this.lCount.Text = gvcounter.GetRowCount().ToString();
}
}
HTH。
我希望这就是你所要求的; - )
