how to refresh my web page using java script

Question

Hello Mate,

I just want to know how can i refresh my page using java script. actually i have a datagrid in my web page(C#).

in that datagrid i have two columns on to display products name and another one is to display an image of "Delete" icon.

if i click a particular row ,that row got deleted. but when i try to save the products name from the datagrid to the database, it still has the same values. the product which i deleted using javascript is also included in the datagrid items.

Could You please help me on this?

my code is,
jscript function:

function Delete(obj,dg)
{
var DG1 = document.getElementById(dg);

if(obj!=null)
{
var par=obj.parentNode;

while(par.nodeName.toLowerCase()!='tr')
{
par=par.parentNode;
}
var param = par.rowIndex;

DG1.deleteRow(param);

return true;
}

return false;

}

Code behind:


if (Grid1.Items.Count != 0)
{
for (int cnt = 0; cnt < Grid1.Items.Count-1; cnt++)
{
object[] Parameters2 = new object[7];
Parameters2[0] = ddlProj_name.SelectedValue;
Parameters2[1] = txtEvt_title.Text;
Parameters2[2] = Grid1.Items[cnt].Cells[0].Text;
Parameters2[3] = Current_User;
Parameters2[4] = Current_Time;
Parameters2[5] = Current_User;
Parameters2[6] = Current_Time;


dbobj3.ExecuteNonQuery("INS_PRODUCTS", Parameters2);


}
}

protected void Grid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if (!(e.Item.Cells[0].Text == "PRODUCTS"))
{
if (((e.Item.ItemType == ListItemType.Item)
|| (e.Item.ItemType == ListItemType.AlternatingItem)))
{


e.Item.Cells[1].Attributes.Add("style", "cursor:hand");
ImageButton img = new ImageButton();
img.ImageUrl = "../images/Remove.gif" ;
e.Item.Cells[1].Controls.Add(img);
e.Item.Cells[1].Attributes.Add("onclick", "return Delete(this,'" + Grid1.ClientID + "');");

}
}
}

Thanks In Advance,
