I Have a Gridview in page.aspx. this gridview i want to pass as a parameter to the constructor of a class1.cs.Can anybody tel me, How can this be done?

Answer 1

So you've got a page with a Gridview:
<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>
And, in the codebehind you populate it like this:
this.gv1.DataSource = FullName.GetDemoCollection(); //Just returns a List<string>;
gv1.DataBind();
And you have another class GridViewRowCounter that does something with GridView, e.g. counts the rows:
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;
}
}
So, to pass your GridView to the Gridviewcounter class you can do something like:
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.
I hope this is what you were asking ;-)
