Response.Clear();
Response.AddHeader("Content-Disposition", "attachment");
Response.AddHeader("filename", "test.xls");
Response.ContentType = "application/vnd.ms-excel";
StringWriter oStringWriter = new StringWriter(new StringBuilder(pstrText));
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
HttpContext.Current.Response.Write(oStringWriter.ToString());
HttpContext.Current.Response.End();
use this code rather than yours...
This is working ...
In your code just replace the spelling of Length in content-length and take a look ... as well.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

In my aspx page,I have a modal popup,on which there is a textbox and a button.
On click of the button(button_click()) ,I have written the code to save the textbox content to database.Everything seems like a simple scenario.
But somehow,when I click the button on the modal popup, it is not firing any event.
I have done the same thing on some other pages also and there it is working properly.
This is my design code :
<ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="addComment_lnk"
BackgroundCssClass="modalBackground" PopupControlID="Panel1">
</ajaxToolkit:ModalPopupExtender>
<asp:LinkButton ID="btn_hide" runat="server"></asp:LinkButton>
<asp:Panel ID="Panel1" CssClass="popBox" runat="server" Style="display: none">
<div>
<p style="text-align: center">
<table>
<tr>
<td class="title">
Post Comment :
</td>
</tr>
<tr>
<td>
<asp:TextBox ID="comments_txt" CssClass="popInput" TextMode="MultiLine" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:Button ID="post_btn" CssClass="button buttonGreen floatRight" OnClick="post_btn_Click"
runat="server" Text="Post" />
<asp:Button ID="cancel_btn" CssClass="button buttonGray floatRight" runat="server"
Text="Cancel" />
</td>
</tr>
</table>
</p>
</div>
</asp:Panel>
<asp:LinkButton ID="addComment_lnk" runat="server">Add Comment</asp:LinkButton>
Can anyone please suggest any possible reasons for the button not firing event.
Thank You.

I have two modules in my project User Side and Admin Side. I want to Use Forms Autentication Only for Admin Module. How can i use Forms Autehntication Only for this. I Tried to Create a another web project for Admin Module. But when i compiling am getting the following error.
Error 1 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
Can i handle these two modules with the main web.config file. Or Should i create another web project like this, If it is then why this Error is coming.

I searched everywhere for answers. I created an msi from the project and it loaded the necessary msm's then I created a different app pool so that this website used the "local system" account instead of Network service. Still got the same error. I am at a loss. any help would be appreciated.

Hi,
I have a DataGrid with the following columns: Remove, ItemName, ItemID, Size, Date, Amount. When the user clicks "Save" I need to cycle through the grid and if any of the Remove Checkboxes are checked, that row needs to get removed, but if the row isnt checked it gets saved to the database using a stored procedure with inputs (Project_ID, ItemID, Size, User). I know how to go through the DataGrid to check to see if the checkbox is checked and then to remove it, but I'm not sure how to take the non-checked rows and add them to the database. Can someone please help me with this code?
protected void btnSave_onClick(object sender, EventArgs e)
{
foreach (GridViewRow row in Control.GridViewRows)
{
CheckBox cboxremove = (CheckBox)row.FindControl("cbxRemove");
if (cboxremove.Checked)
{
RemoveCheckedTitles();
}
else
{
???????????????
}
}
Please Help! Thanks

Thank you for your reply, however, I am not sure how to read in the data from the columns (columns: Remove, ItemName, ItemID, Size, Date, Amount) into my stored procedure that takes the following inputs (Project Id, ItemID, Size, User) where ProjectID and User are from the session but ItemID and Size are from the DataGrid.

I think you can implement template field for those columns ,from where you want the data to be retrieved just like you are using the checkboxes and getting it by using row.findcontrol ,same try for this template field also.

If you want to show a jacascript alert then use the following code.
Page.ClientScript.RegisterClientScriptBlock(this.GetType(),"key","<script>alert('Message')</script>");

I am new to this. I built a web site using Scott Mitchell's example, and it works great. However, I want to move the business logic and the Data Access logic to a different machine. What must I do to achieve this?
Thanks,

You know you want that on different machines but you don't know what it takes and therefore what it means for that to execute on different machines. So how do you know you want it, if you don't know what it is?

I have written an application bases on Scott Mitchell's Data Access Tutorial. I created the DAL (Data Access Layer) and the BLL (Business Logic Layer) but they reside on the same machine as the Presentation layer. I would like to seperate them and put my data on a machine that is behind a firewall. Do you know how to do this?
Thanks,
|

The machines would have to talk to each other by being on the same network, or they would need to use a webservice to communicate with each other. I would personally put all the code on one machine, and perhaps put the DB on a different machine on the same network.
