On Gridview RowCommand button text is not getting changed in ASP.NET using C#

I want to update the text of the btn_Update which is inside the EditTemplate of gridview. For that I wrote the code shown here. But the text is still shown as Reject, even if I am trying to update the text to Approve.
Here's my markup and code:
<asp:GridView ID="rptHotoIPDataInfo" runat="server" AutoGenerateColumns="False" CssClass="table table-bordered nowrap tblrptHotoIPDataInfo"
AllowPaging="True" PageSize="20" OnPageIndexChanging="rptHotoIPDataInfo_PageIndexChanging"
DataKeyNames="SAP_ID" OnRowEditing="rptHotoIPDataInfo_RowEditing" OnRowUpdating="rptHotoIPDataInfo_RowUpdating"
OnRowCancelingEdit="rptHotoIPDataInfo_RowCancelingEdit" OnRowDataBound="rptHotoIPDataInfo_RowDataBound"
OnRowCommand="rptHotoIPDataInfo_RowCommand">
<Columns>
<asp:TemplateField HeaderText="Approved / Reject" ItemStyle-Width="80px"> <%--"Accepted/Rejected (By default checked means approved)"--%>
<ItemTemplate >

</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Action" ItemStyle-Width="120px">
<ItemTemplate>
<asp:Button ID="btn_Edit" runat="server" Text="Reject" CommandName="Edit" Enabled="false" CssClass="btn btn-blue" CommandArgument="<%# Container.DataItemIndex %>" />
</ItemTemplate>
<EditItemTemplate>
<asp:Button ID="btn_Update" runat="server" Text="Reject" CommandName="Update" CssClass="btn btn-blue" />
<asp:Button ID="btn_Cancel" runat="server" Text="Cancel" CommandName="Cancel" CssClass="btn btn-blue" />

</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ID" ItemStyle-Width="50px">
<ItemTemplate>
<asp:Label ID="lbl_ID" runat="server" Text='<%#Eval("ID") %>'></asp:Label>

<asp:BoundField DataField="REJECTED_BY" HeaderText="Last Updated by">
<ItemStyle CssClass="labelbold" Width="10px" />
</asp:BoundField>
</Columns>
</asp:GridView>
And the code behind is:
protected void rptHotoIPDataInfo_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Edit")
{
int rowIndex = Convert.ToInt32(e.CommandArgument);
GridViewRow row = rptHotoIPDataInfo.Rows[rowIndex];
string name = row.Cells[9].Text;
var clickedButton = e.CommandSource as Button;
var clickedRow = clickedButton.NamingContainer as GridViewRow;
var clickedUserName = clickedRow.Cells[9].Text;
if (clickedUserName == "Approved")
{
clickedButton.Text = "Reject";
}
else if (clickedUserName == "REJECTED")
{
clickedButton.Text = "Approve"; // this statement is not updating the text
}
}
}

DropDownList ddl = e.Row.FindControl("DropDownList1") as DropDownList;
if (ddl != null)
{
ddl.SelectedIndexChanged += new EventHandler(DropDownList1_SelectedIndexChanged);
}
}
}
the drop down selectedindexchanged event does not fire. I am trying to do as my drop down value changes at run time , in my database value get updates.

remove the event handler adding code from PaperReviewing_RowDataBound since you are already attached it from the markup
in your page load
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
DataBindGrid();
}
}

protected void updateBack()
{
Response.Write(I want to get the deleted seatOrderID here!!!!!);
}

Using this code, you can fetch the ID in the RowDeleting event:
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
GridViewRow gvr = (GridViewRow)GridView1.Rows[e.RowIndex];
string id = String.Empty;
Label lbl = (gvr.FindControl("Label1") as Label)
if (lbl != null)
{
id = lbl.Text;
}
}
You can fetch any control in the row, using the FindControl() method.

How to bind hovermenuextender control to a row with multiple columns in a dynamic gridview?

I wish to attach a hovermenu pop up to rows of a gridview which is dynamically populated from a datasource. I tried to set TargetcontrolId property of hovermenuextender control to row unique Id on occurence of rowdatabound event. But rather than appearing on the right side of each row, pop up is appearing on the right side of header row. Can somebody help me resolve this problem? I used below code for the same
CodeBehind:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HoverMenuExtender hoverMenu =(HoverMenuExtender)e.Row.FindControl("hme2");
if (hoverMenu != null)
{
hoverMenu.TargetControlID = hoverMenu.Parent.Parent.UniqueID;
}
}
}
}

Nested grid edit doesn't work

I'm stuck on this problem where I have grid within grid where the nested grid is editable. I can't get the edit working. What's complicates things is that the nested grid is inside a modal popup extender.
It works to the point where I click on the edit button. Then the EmptyDataText property kicks in with the message. If I click on it second time the grid opens in edit mode but the update/cancel buttons don't work. The cancel button when click displays the EmptyDataText property.
Another issue is that this nested grid doesn't use a object data source so I'm going to have to all the updating and deleting in the code file. Not sure now to do that either.
I would like some advice as to how to make this corrected. Here is the code:

I will try to answer part of your question, updating and deleting the code. you need to take advantage of the "onrowcommand" for the inner gridview (OnRowCommand).
