  foreach (DataControlFieldCell cell in e.Row.Cells)
                    {

                        {
                            // Must use LinkButton here instead of ImageButton
                            // if you are having Links (not images) as the command button.
                            ButtonField button = new ButtonField();
                            if (button != null && button.CommandName == "Delete")
                                // Add delete confirmation
                                button.onclientclick= "if (!confirm('Are you sure " +
                                       "you want to delete this record?')) return;";

As i understand ButtonField does not support OnClientClick property.

Alternate solution would be to use a TemplateField to define ASP Button and call its Onclick event as follows.

<asp:gridview id="GridView1" runat="server" width="100%" xmlns:asp="#unknown">
                   DataKeyNames="NoticeId" onrowdatabound="GridView1_RowDataBound"
                   onrowdeleting="GridView1_RowDeleting" AutoGenerateEditButton="True"
                   onrowediting="GridView1_RowEditing">
                   <columns>

   <asp:templatefield>
                 <itemtemplate>
                     <asp:button id="Button1" runat="server" text="Delete" commandname="Delete" onclientclick="return ConfirmDeletion();" />
                 </itemtemplate>


                   </asp:templatefield></columns>
               </asp:gridview>

//Script in header tag

<script>

function ConfirmDeletion()

{

 return (confirm("Are you sure you want to delete the record?"));

}

<script>

show javascript using response.write in code

JavaScript

response.write("<script>return confirm('Are You Sure')</script>");

You answered the same question 3 times??? Why? What is the necessity? Use your Improve solution button if you need to update your answer instead of add another solution..

Solution 5

If you change the line:

ButtonField button = new ButtonField();

into:

LinkButton button = control as LinkButton;

it should work.
