ASP.NET GridView, change properties in Button from ItemTemplate - asp.net

Question

I have a GridView that renders books from a database.
In each line a Delete/Edit button is rendered. When the user clicks the Edit button, I want the the Cancel and Update buttons to appear and the Edit buttton to become disabled.
I thought about using the onClick event for the Edit button along with the GridView row for getting the appropriate button based on the row, setting the Edit button's Enable property to false and the visibility of the Cancel and Update buttons to true.
However, it seems I can not change the properties even for the Edit button that I get from the event handler.
Here is the code.
protected void EditButton_Click(object sender, EventArgs e)
{
Button Sender = (Button)sender;
Sender.Text = "??"; //THIS CHANGE IS NOT APPLIED!!
//Button Sender = (Button)sender;
//GridViewRow grdRow = (GridViewRow)Sender.Parent.Parent;
//Button btn = (Button)grdBooks.Rows[grdRow.RowIndex].Cells[1].FindControl("CancelButton");
}
<asp:GridView
id="grdBooks"
DataSourceID="srcBooks"
DataKeyNames="Product_ID"
AutoGenerateColumns="false"
CssClass="products"
GridLines="none"
Runat="server" OnRowCreated="grdBooks_RowCreated">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Button CausesValidation="false" ID="DeleteButton" CommandName="Delete" runat="server" Text="Delete" />
<asp:Button CausesValidation="false" ID="EditButton" CommandName="Edit" runat="server" Text="Edit" OnClick="EditButton_Click" />

<asp:Button CausesValidation="false" ID="UpdateButton" Enabled="false" Visible="true" CommandName="Update" runat="server" Text="Update" />
</ItemTemplate>
</asp:TemplateField>
<%-- <asp:CommandField ButtonType="Button" ShowEditButton="true"/>--%>
<asp:BoundField
DataField="ISBN"
ReadOnly="true"
HeaderText="ISBN" />
<asp:BoundField
DataField="Title"
ReadOnly="true"
HeaderText="Title" />
<asp:BoundField
DataField="First_Name"
ReadOnly="true"
HeaderText="First Name" />
<asp:BoundField
DataField="Last_Name"
ReadOnly="true"
HeaderText="Last Name" />
<asp:BoundField
DataField="Price"
HeaderText="Price" />
<asp:BoundField
DataField="Quantity"
HeaderText="Quantity" />
</Columns>
</asp:GridView>

Answer 1

After the event is handled, the page probably reloads and resets the original text.
Maybe you could use JavaScript to do what you need.
