problem in outlook

I've got a Imagebutton in a repeater.
Code:

<asp:Repeater ID="repImages"  runat="server">
                    <ItemTemplate>                       
                        <div>
                            <div><asp:ImageButton ID="btnDeleteImage" Width="7" Height="7" runat="server" AlternateText="Verwijder afbeelding"  OnClientClick="return confirm('Weet u zeker dat u deze afbeelding wil verwijderen?');" OnClick="ImageButton_OnClick" ImageUrl="~/images/spacer.gif" /></div>
                            <img id="imgImage" runat="server" src='<%# GetOccasionPath(int.Parse(Eval("ID").ToString()),Eval("BaseFileName").ToString(), TypeImage.thumbnail) %>' />
                        </div>
                    </ItemTemplate>
                </asp:Repeater> 

It is displayed well, but if i press the button btnDeleteImage he doesn't even run ImageButton_OnClick , also there is no data included just for testing...
protected void ImageButton_OnClick(object source, EventArgs e)
    {
       
    }

But still i get this error:

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Also enableEventValidation="true" is placed in the page.
What can i do to solve this?

HI

My project upgrade to MVC3 R2, but there is a problem with validation metadata when the model inherit from other class.  In MVC2 all the child class will inherit the validation metadata, but in MVC3 R2, it will be not include the validation metadata of parent class. Is this expected?

Hello

I am using Visual SVN Server and Tortoise SVN as a Client. 

After I get update and ascx file is merged visual sdutio displays warning and I must set merged file line encoding.

The line endings in the following file are not consistent. Do you want to normalize line endings?

I believe that it's due to default SVN merge tool or visual svn behaviour for currently opened files. 

Hi,

      I'm trying to export a dataset to excel directly. I'm repeating, it's a dataset to excel (NOT DATA GRID OR GRID VIEW TO EXCEL). The problem I face is formatting. I'm exporting the excel which has aroung 13 columns.

    A column should be in dd/MM/yyyy 00:00:00 format. Time will always be 00:00:00. It is exporting in correct format only, but for example when the date is Jan 05, 2010, when it comes from database it shows correct format as 05/01/2010 00:00:00. When it binds, it binds as 5/1/2010 00:00 which is not suppose to happen.

 And the other problem is with the decimal formatting. I need 2 decimal places at the last. In c# code, I'm converting to decimal with 2 decimal places, but when it binds, it won't happen. I tried inserting a ' (colon) before the text is entered, but the cell is not converted into a text field

   Can anyone give me a solution for this?

i tried to get current date and time using

              DateTime dtCurrTime = DateTime.Today;


            //string d
            Label1.Text = dtCurrTime.ToString();

            //DateTime dt = DateTime.Now.Hour;

            Label2.Text = DateTime.Now.Date.ToString();

 i'm getting the date correct but time is always getting default value

12/15/2010 12:00:00 AM

i grid view contain the following coloum

id    name         DateofBirth                  DateofJoining 

1       a            22-Aug-1980                      10-jan-2000

1       a            22-may-1980                      20-feb-2000

1       a            12-Feb-1980                      15-mar-2000

1       a            3-Aug-1980                      7-jan-2000

how to sort if we click   DateofBirth or Dateofjoining and not sort any where if we click(Id,Name)

I have the following code:

Protected Sub btnAdmin_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Server.Transfer("~/Admin/Default.aspx")
End Sub

that runs when a user clicks the admin button

It works fine in firefox, but in IE it doesn't work.
 

Hi I want a simple nested gridview to display data records, that's it, very basic no edits, etc. Just when user clicks on grid a nested grid

appears for order showing.  Right now I get an error, object expected when I click on the grid defaulting at runtime. I don't have

gifs for images, or an image folder, I don't think that would cause an error, or the second grid not to display???

Here's my code. Any help would be deeply appreciated. Many thanks!

<script>
 
   function switchViews(obj,row)
        {
            var div = document.getElementById(obj);
            var img = document.getElementById('img' + obj);
           
            if (div.style.display=="none")
                {
                    div.style.display = "inline";
                    if (row=='alt')
                      {
                           img.src="Images/expand_button_white_alt_down.jpg" mce_src="Images/expand_button_white_alt_down.jpg";
                       }
                   else
                       {
                           img.src="Images/Expand_Button_white_Down.jpg" mce_src="Images/Expand_Button_white_Down.jpg";
                       }
                   img.alt = "Close to view other customers";
               }
           else
               {
                   div.style.display = "none";
                   if (row=='alt')
                       {
                           img.src="Images/Expand_button_white_alt.jpg" mce_src="Images/Expand_button_white_alt.jpg";

                           img.src="Images/Expand_button_white.jpg" mce_src="Images/Expand_button_white.jpg";
                       }
                   img.alt = "Expand to show orders";
               }
       }

We tried to add a Entity model using Razor here was the syntax:

@ModelType BID.Data.Entities.PlumbingPermit

@Code

    ViewData("Title") = "Index"

    Layout = "~/Views/Shared/_Layout.vbhtml"

End Code

<h2>Index</h2>

@Html.EditorForModel 

When you build you get the following error message:

Error 1 Syntax error. C:\Documents and Settings\thacker\My Documents\Visual Studio 2010\Projects\Public Works\BuildingInspectionsSystem\Source Code\BID.Web.VB\Views\Home\Index.vbhtml BID.Web.VB

I'm having a problem with a dropdown throwing an error:

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

...Only Sometimes. 

I am using an updatepanel, with a bunch of dropdowns that have an onchange for Javascript, that use ajax (partial page postback). They ALL work fine.

The problem is: I have two dropdowns at the top (also inside the updatepanel) that let me change the current month or year. Sometimes...they change the page (response.redirect), and sometimes they throw that error above.

Also, they are the Only two buttons on the page that aren't doing an "onchange" and then ajax stuff....they are actually posting back the entire page to the server (or trying to). 

Thanks
