RowUpdating event in grid view is not firing

I have a grid view and I wanna update data in the row. I have written a C# code and I've noticed that the RowUpdating event is not firing.
I am using Template Field in my grid. The RowCommand event is working properly, however, the RowUpdating event is not firing.
What should I do? I need your help, please.
The event is like the below:
protected void grdPeople_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
try
{
SqlConnection con = new SqlConnection(strCon);
if (con.State == ConnectionState.Closed)
con.Open();
SqlCommand com = new SqlCommand("InsertUpdatePerson", con);
com.CommandType = CommandType.StoredProcedure;
com.Parameters.AddWithValue("#pr_id", Convert.ToInt32(grdPeople.DataKeys[e.RowIndex].Value.ToString()));
com.Parameters.AddWithValue("#pr_name", (grdPeople.FooterRow.FindControl("txtNameFooter") as TextBox).Text.Trim());
com.Parameters.AddWithValue("#pr_gender", (grdPeople.FooterRow.FindControl("rdoMaleFooter") as RadioButton).Checked);
com.Parameters.AddWithValue("#pr_nationality", (grdPeople.FooterRow.FindControl("txtNationalityFooter") as TextBox).Text.Trim());
com.Parameters.AddWithValue("#pr_idn", (grdPeople.FooterRow.FindControl("txtIDnoFooter") as TextBox).Text.Trim());
com.Parameters.AddWithValue("#pr_passport", (grdPeople.FooterRow.FindControl("txtPassportFooter") as TextBox).Text.Trim());
com.Parameters.AddWithValue("#pr_resident", (grdPeople.FooterRow.FindControl("rdoYesFooter") as RadioButton).Checked);
com.Parameters.AddWithValue("#pr_phone", (grdPeople.FooterRow.FindControl("txtPhoneFooter") as TextBox).Text.Trim());
com.Parameters.AddWithValue("#pr_email", (grdPeople.FooterRow.FindControl("txtEmailFooter") as TextBox).Text.Trim());
com.Parameters.Add(new SqlParameter("#ERR_MESSAGE", SqlDbType.NVarChar, 255)).Direction = ParameterDirection.Output;
com.Parameters.Add(new SqlParameter("#ERR_NUMBER", SqlDbType.Int)).Direction = ParameterDirection.Output;
com.ExecuteNonQuery();
int ErrNo = int.Parse(com.Parameters["#ERR_NUMBER"].Value.ToString());
if (ErrNo != 0)
{
lblSuccess.Text = "Data saved successfully.";
grdPeople.EditIndex = -1;
}
else
{
lblError.Text = com.Parameters["#ERR_MESSAGE"].Value.ToString();
}
}
catch (Exception ex)
{
lblSuccess.Text = "";
lblError.Text = ex.Message;
}
}

I added the grid design above to show you how I designed it and how I set its properties.
Thank you.

In your GridView's EditItemTemplate, you miss out a button with CommandName="Update" which this button will trigger the grdPeople_RowUpdating event.
<EditItemTemplate>
<asp:ImageButton runat="server" ImageUrl="~/icons/save.png" CommandName="Save" ToolTip="Save" Width="20px" Height="20px" ValidationGroup="Fields"/>
<asp:ImageButton runat="server" ImageUrl="~/icons/cancel.png" CommandName="Cancel" ToolTip="Cancel" Width="20px" Height="20px" />
</EditItemTemplate>
SOLUTION
Change the Save button CommandName's value from CommandName="Save" to CommandName="Update".
<EditItemTemplate>
<asp:ImageButton runat="server" ImageUrl="~/icons/save.png" CommandName="Update" ToolTip="Save" Width="20px" Height="20px" ValidationGroup="Fields"/>
<asp:ImageButton runat="server" ImageUrl="~/icons/cancel.png" CommandName="Cancel" ToolTip="Cancel" Width="20px" Height="20px" />
</EditItemTemplate>

var RadDropDownList = (RadDropDownList)item.FindControl("ddlAlbums");

You need to be sure its a item type, not command item
if((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
{
var RadDropDownList = (RadDropDownList)e.item.FindControl("ddlAlbums");
if(RadDropDownList != null)
{
//do what you need here
}

And here is my backend:
protected void CheckBox_CheckChanged(object sender, EventArgs e)
{
GetData();
SetData();
BindSecondaryGrid();
}
However the page does not refresh when checkbox is checked why is that?

I had to remove onclick = "Check_Click(this)" to fix the proble the onClick is useless.
Change
<asp:CheckBox ID="chkRow" AutoPostBack="true" EnableViewState="true" runat="server" onclick = "Check_Click(this)" OnCheckedChanged="CheckBox_CheckChanged" />
to
<asp:CheckBox ID="chkRow" AutoPostBack="true" EnableViewState="true" runat="server" OnCheckedChanged="CheckBox_CheckChanged" />

pls help me

protected void btnSubmit_Click(object sender, EventArgs e)
{
if (gvActList.Rows.Count > 0)
{
foreach (GridViewRow row in gvActList.Rows)
{
RadioButton rdYes= (RadioButton)row.FindControl("rdYes");
RadioButton rdNo = (RadioButton)row.FindControl("rdNo");
RadioButton rdNone = (RadioButton)row.FindControl("rdNone");
if (rdYes != null && rdNo != null && rdNone != null)
{
if (rdYes.Checked == true)
{
//some code
}
else if (rdNo.Checked == true)
{
//some code
}
}
}
}
}
You can use above code on the button click. One suggestion is to use RadiobuttonList instead of RadioButton so that it will reduce the code.

on button click declare a gridview row. make a for loop and find the radio button in each row and other controls whose value you want to update. check the conditions as per your requirement and update accordingly
