protected void chkcheckquery_CheckedChanged(object sender, EventArgs e)
{
CheckBox chkTest = (CheckBox)sender;
GridViewRow grdRow = (GridViewRow)chkTest.NamingContainer;

// CheckBox che = (CheckBox)grdRow.FindControl("chkcheckquery");

if (chkTest.Checked)
{
string get_value = gvqueriescheck.Rows[0].Cells[1].Text;
ListBox1.Items.Add(get_value);
}

//for (int i = 0; i < gvqueriescheck.Rows.Count; i++)
//{
// CheckBox chbTemp = gvqueriescheck.Rows[i].FindControl("chkcheckquery") as CheckBox;
// if (chbTemp.Checked)
// {
// string get_value = gvqueriescheck.Rows[i].Cells[1].Text;
// ListBox1.Items.Add(get_value);
// //Code for Deletion

// }
//}

}

I would have debugged the code by putting a breakpoint on the above given method and on the line ListBox1.Items.Add(get_value);
Debugging line by line will tell you why it is happening.

Hi Swaroopa check the following code works for you.Add the items to Listbox out of for loop.

string get_value = "";
        for (int i = 0; i < gvqueriescheck.Rows.Count; i++)
        {
            CheckBox chbTemp = GridView1.Rows[i].FindControl("chkcheckquery") as CheckBox;
         if (chbTemp.Checked)
         {
              get_value = gvqueriescheck.Rows[i].Cells[2].Text;
         }
}
ListBox1.Items.Add(get_value);
