Hi,
I could not find any direct way to do this.
But u can use ItemDataBound event of datalist.
U need to put hyperlink in datalist ItemTemplate without setting its NavigateUrl property.
This property u can set at runtime while datalist it bound to the datasource.
Your hyperlink should be like following.
<asp:HyperLink ID="HyperLink1" runat="server"></asp:HyperLink>
I have put one label control which will have the value which we want make querystring.
I have set its visible property = false;
<asp:Label ID="lblusernamehidden" runat="server" Text='<%# Eval("username") %>' Visible="false"></asp:Label>
now I am setting hyperlink's navigateurl property in ItemDataBound event of datalist.
protected void dlst_ItemDataBound ( object sender, DataListItemEventArgs e )
{
HyperLink hl = ( HyperLink )e.Item.FindControl( "HyperLink1" );
Label lbl = ( Label )e.Item.FindControl( "lblusernamehidden" );
if ( hl != null && lbl != null )
{
hl.NavigateUrl = "~/TargetPage.aspx?username=" + lbl.Text;
}
}
this way you can get querystring dynamically in hyperlink.
also set Datalist's OnItemDataBound property to "dlst_ItemDataBound".
I hope this will help you.
Thanks and Regards,

That is how it is working. It will postback the data. If you are doing anything in pageload and you don't want to execute that when page is postingaback, write that in
!isPostBack<br />
<br />
<code>if ( !isPostBack )
{
}
</code>

U can use following code block to creat the output in word file.where u'll need to use the name of control in place of CTRL below, which have data to send to output file.
Response.Clear()
Response.AddHeader("content-disposition", "attachment;filename=FileName.doc")
Response.Charset = ""
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.Buffer = True
Response.ContentType = "application/vnd.word"
Me.EnableViewState = False
Dim oStringWrtr As New System.IO.StringWriter
Dim oHTMLTxtWrtr As New System.Web.UI.HtmlTextWriter(oStringWrtr)
CTRL.RenderControl(oHTMLTxtWrtr)
Response.Write(oStringWrtr.ToString())
Response.End()
With Thanks & Regards

I recommend buying a book on ASP.NET and working through it, you obviously have no idea how it works.

Form A displays qty and other details, allows user to purchase item by entering required qty.
If Form A is used by user, and for the first user it display 500 and he enters the qty he wants to purchase is 100, Form A should display for the second user with qty 400 even though qty is not posted to database.
Thank you

That in the long run, will be a bad application design. It's far far maintainable and trustworthy if you post each transaction to the database. You can always rollback transactions if they were not completed or cancelled.
As for your requirements, you can save the total available quantity in a global static variable and subtract each user's quantity from it.

Hi,
I have an application that generates .html and .mht files.Page generation is working good, but Some times there is a situation when contents in .html or .mht files goes out of A4(standard size for printing) size.So when I take a print of this page whole contents don't come.Some contents are cut down.But I want to print out the page with whole contents.What can I do?

There's nothing much you can do except resize the page dynamically to fit into an A4 or have a "Printer Friendly" page link separately.

Hi Guys,
We are using Asp.Net,C# for coding our application. Also we've used CSLA.Net.
I haven't faced any problems with .Net 2.0 installation.
when I try to run the application. Once I provide UID and Password.
The following version related Exception occurs from code
(FormsAuthentication.GetRedirectUrl(username, false).ToUpper().Contains("DEFAULT.ASPX") (or)
FormsAuthentication.RedirectFromLoginPage(username, false);
EXCEPTION:
Type is not resolved for member 'CSLA.Security.BusinessPrincipal,CSLA, Version=2.200.4.0, Culture=neutral, PublicKeyToken=null'.
If any of you knows the solution for this problem. Please post your answers.

Hi,
As I know that any thing you change through the Javascript, is not saved in the view state. Hence you can get it in the postback.
Yoy can get only selected value through request.form(name of the list control).
If you require all the inserted item you need to do it logically.

Hi,
when the admin login, iam displaying the list of users for the admin to view. when the admin select the details of a user there iam displaying the user details and also a button (say, Log into Resource Center as this user) in a seperate page. Here i have to pass the username and password of the user to a new url in a new window.How can we do this.
My code
StringBuilder strntrc = new StringBuilder();
strntrc.Append(""+Environment.NewLine);
strntrc.Append("" + Environment.NewLine);
strntrc.Append("" + Environment.NewLine);
strntrc.Append("" + Environment.NewLine);
strntrc.Append("");
This code is giving me error while execution:
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.
I googled about this error but couldn't find the relevant source.
Please suggest me how can i resolve this.
Thanks
