Exporting DataSet to Excel in asp.net problem

In my previous articles I talked about exporting GridView to excel. Although most of the time you will be exporting the content displayed on the screen but sometimes it might not be the case. In this article I will demonstrate how to export a DataSet to excel.

hello i am facing a problem in microsort outlook 2003.

i have an email template in html in which i am sending data from asp.net page and according to condition making display:none of sm <tr> dymamically.

it is working fine when received in outlook. but when we press forward button to forward mail

then hidden rows also displays.

Any idea to get rid of this problem.

Please suggest me

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. 

i tried to get current date and time using

              DateTime dtCurrTime = DateTime.Today;

            //DateTime dt = DateTime.Now.Hour;

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

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";
                       }
                   else
                       {
                           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
