How to store values to arraylist and also same value display

hey palani mca,

1)you can take input from user and bind the gridview like below.

string[] arr1D = { "abhi", "ram", "ganesh", "nirranjan" };
Grid1D.DataSource = arr1D;
Grid1D.DataBind();

2)you can remove the selected row from gridview i assume here you are selected here to checkbox, you can checked checkted to deleted row.

ArrayList del = new ArrayList();
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkDelete = (CheckBox)row.Cells[0].FindControl("CheckBox1");
if (chkDelete != null)
{
if (chkDelete.Checked)
{
string id = row.Cells[1].Text;
del.Add(id);
}
}
}
}  
GridView1.DataBind();
 

Storing data in arraylist:
ArrayList list = new ArrayList();
list.Add("One");
list.Add("Two");

Retrieving data from arraylist:
foreach (int i in list)
{
  Console.WriteLine(i);
 }
