asp.net Ajax MaskedEditExtender

I am trying to use a MaskedEditExtender in a Gridview, with a Date/Time Template Field.

When i enable the Extender, then when i choose to edit the row, nothing appears. As soon as i Disable the extender than the edit boxes appear.

Any ideas?

<cc1:MaskedEditExtenderID="MaskedEditExtender3"runat="server"MaskType="DateTime"AcceptAMPM="true"

AutoComplete="true"ClearTextOnInvalid="true"mask="99/99/9999 99:99:99"

Enabled="False"TargetControlID="TextBox1">

Hi Kevers,

To see the effect, MaskedEditExtender's Enabled is set to "true". Here is a sample which you can reference to.

<form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"> <Columns> <asp:CommandField ShowEditButton="True" /> <asp:BoundField DataField="EmployeeID" HeaderText="EmployeeID" InsertVisible="False" ReadOnly="True" SortExpression="EmployeeID" /> <asp:BoundField DataField="LastName" HeaderText="LastName" SortExpression="LastName" /> <asp:BoundField DataField="FirstName" HeaderText="FirstName" SortExpression="FirstName" /> <asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" /> <asp:TemplateField> <ItemTemplate> 2007-10-04 10:20:30 </ItemTemplate> <EditItemTemplate><asp:TextBox ID="TextBox1" runat="server" Text="10/04/2007 10:20:30"></asp:TextBox> <ajaxToolkit:MaskedEditExtender ID="MaskedEditExtender1" runat="server" Mask="99/99/9999 99:99:99" MaskType="DateTime" TargetControlID="TextBox1" AcceptAMPM="true"AutoComplete="true" ClearTextOnInvalid="true" Enabled="true"> </ajaxToolkit:MaskedEditExtender> </EditItemTemplate> </asp:TemplateField> </Columns> </asp:GridView><asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NORTHWNDConnectionString%>" SelectCommand="SELECT [EmployeeID], [LastName], [FirstName], [Title] FROM [Employees]" DeleteCommand="DELETE FROM [Employees] WHERE [EmployeeID] = @.EmployeeID" InsertCommand="INSERT INTO [Employees] ([LastName], [FirstName], [Title]) VALUES (@.LastName, @.FirstName, @.Title)" UpdateCommand="UPDATE [Employees] SET [LastName] = @.LastName, [FirstName] = @.FirstName, [Title] = @.Title WHERE [EmployeeID] = @.EmployeeID"> <DeleteParameters> <asp:Parameter Name="EmployeeID" Type="Int32" /> </DeleteParameters> <UpdateParameters> <asp:Parameter Name="LastName" Type="String" /> <asp:Parameter Name="FirstName" Type="String" /> <asp:Parameter Name="Title" Type="String" /> <asp:Parameter Name="EmployeeID" Type="Int32" /> </UpdateParameters> <InsertParameters> <asp:Parameter Name="LastName" Type="String" /> <asp:Parameter Name="FirstName" Type="String" /> <asp:Parameter Name="Title" Type="String" /> </InsertParameters> </asp:SqlDataSource> </form>

I hope this help.

ASP.Net AJAX Enabled Web Application template missing

I have installed ASP.NET2.0 AJAX Extensions 1.0 but I cannot find a template for the above when I try to create a new project and I believe there is one available from another post? If I try a new website, I get the AJAX enabled web site template, but what I really need is the web application template.

Anyone have any ideas as to why it is not appearing? Or what settings do I need to migrate from a ajax enabled website to a web application project to enable ajax?

Thanks in advance

Hi,

Thank you for your post!

As far as I know, there is none web application project template and AJAX web application project template in Visual Studio 2005/2008.

And we can take a website as a web application project.

If you really need a solution for a web site, you can add an empty solution, then add website to it,and other related project(e.g. class library project).

If you have further questions, let me know.

Best Regards,

argumentNullException with gridview paging with toolkit control in template field

hi

I have a simple page with a gridview. the item template has an AjaxControlToolkit:confirmButtonExtender. All is good until I tried to enable custom paging in the gridview and object data source. the first page loads but when I click on the 2nd page I get an argumentNullException thrown. The Page argument is null. I can make paging work by removing the AjaxControlToolkit:confirmButtonExtender. Anybody got any ideas about this?

Value cannot be null. Parameter name: page

here's an explanation of the underlying problem:

for now i can continue without the ConfirmButtonExtender. And I can tell the boss that I didn't break it... Yipee!
