When I am clicking the gridview edit button from ItemTemplate of TemplateField it is not showing me the update and cancel buttons from EditItemTemplate of TemplateField.

Actually what is happening is when i click the edit button it refreshes the gridview and finally the data is binded again but the update and cancel buttons are not appearing at all can anyone tell me where is the exact problem.

What I have tried:

<asp:TemplateField ItemStyle-Width="30px" ItemStyle-Wrap="false">
    <ItemTemplate>
        <asp:Button ID="btnEdit" runat="server" Text="Edit" CssClass="btn btn-link text-center" ToolTip="edit data" CommandName="Edit" UseSubmitBehavior="false" CausesValidation="false" OnClick="btnEdit_Click" />
        <button type="button" id="btn" runat="server" disabled onserverclick="btn">
            Approve
        </button>
    </ItemTemplate>
    <EditItemTemplate>
        <asp:Button ID="btnUpdate" runat="server" Text="Update" CommandName="Update" CssClass="btn btn-link" UseSubmitBehavior="false" />
        <asp:Button ID="btnCancel" runat="server" Text="Cancel" CommandName="Cancel" CssClass="btn btn-link" UseSubmitBehavior="false" />
    </EditItemTemplate>                                            
</asp:TemplateField>

Do you see other data is properly bound to your grid control? Can you add that code as well

If the EnableViewState=false then postbacking the data and remains same.
When EnableViewState=true then getting error "Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."

Finally I got the solution..... Using the bind data method from code behind it is not working properly and i deleted it and added sqldatasource to bind the data from the database. Now it is working properly as expected.....

But anyone can explain me why gridview is not getting as expected when binding data from the method in the code behind.... I don't know please explain me clearly.....
