I don't think so, I think you can pass something on the URL to tell your HTTP handler which action to perform. If you just create a new HTTP handler using the VS IDE, you can point to that, and write code in there to return whatever you like.

you can't install a program from ASP.NET. You download a file by providing a link to it, or if you prefer, using Response.BinaryWrite to pass it back from a page.

Well, why do you tink it's wrong ? You don't tell is if there's an error, if there's a wrong result, or what.

First problem: \ is used to escape things. So , \" puts a quote in the string, it does not equate to a \ in quotes. "\\" or @"\" is what you need
Second problem: this code assumes that there's a character after the slash in currentUser. If not, it will blow up.

how can i do this

Re: hyperlinkculumn in the grid

23-Jun-08 20:23

Why are you adding it in code instead of in the aspx ?

You can subscribe to the itemdatabound event and look for hte column there, but it would be better to build a template that just builds the URL

Hi,

instead of using hyperlink column, use linkbutton. find attached the code below.

aspx file code:
---------------

<asp:DataGrid DataKeyField="event_id" ID="eventsGrid" runat="server" CssClass="textbld"
AllowSorting="True" AutoGenerateColumns="False" Width="518px" OnItemDataBound="eventsGrid_ItemDataBound"
AlternatingItemStyle-CssClass="alternativeTxt" BorderColor="White" BorderStyle="Solid"
BorderWidth="1px" CellPadding="0" HorizontalAlign="Left" >
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<EditItemStyle BackColor="#2461BF" />
<SelectedItemStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<AlternatingItemStyle CssClass="alternativeTxt" />
<ItemStyle HorizontalAlign="Left" CssClass="itemTxt" />

<Columns>



<asp:BoundColumn DataField="event_id" Visible="False"></asp:BoundColumn>



<asp:TemplateColumn HeaderText="Ort" HeaderStyle-CssClass="padlist">
<ItemTemplate>
<asp:LinkButton ID="lnkCity" runat="server" CommandArgument='<%# Eval("event_id") %>'
OnCommand="lnkCity_Command" CssClass="Blacklink"></asp:LinkButton>
</ItemTemplate>
<ItemStyle CssClass="eventsTxt" />
</asp:TemplateColumn>

</Columns>
<HeaderStyle CssClass="head_txt Head_R1" />
</asp:DataGrid>

.cs file code:
---------------

In the onclick event of the linkbutton in the datagrid, give the link url as below.

protected void lnkCity_Command(object sender, CommandEventArgs e)
{
Response.Redirect("Popup.aspx");
}

Cross-Page Posting

23-Jun-08 19:56

Hello Friends,

I want to use the my Public property values in my destination page using the Cross-Page Posting

Page1.aspx

public string myName
{
get
{
return txtName.Text;
}
}

Page2.aspx

<%@ PreviousPageType VirtualPath="~/Page1.aspx" %>

and to use the value of myName property in Page2.aspx i'm using the following code

txtName.Text = PreviousPage.myName;

or

Rough1 myRough;
myRough = (Rough1)PreviousPage;
txtName.Text = myRough.myName;

but it's throwing an error "Object reference not set to an instance of an object"

Christian Graus23-Jun-08 20:04

23-Jun-08 20:04

Which line throws the error ?

.NET- India 23-Jun-08 20:22

23-Jun-08 20:22

txtName.Text = PreviousPage.myName;

this line throwing the error

Christian Graus23-Jun-08 20:25

23-Jun-08 20:25

Rough1 myRough;
myRough = (Rough1)PreviousPage;
txtName.Text = myRough.myName;

Line 2 would throw if it failed, so I assumed txtName is null. Where are you calling this code and where does txtName come from ?

.NET- India 23-Jun-08 20:34

23-Jun-08 20:34

Actually i've two textbox named "txtName"

first textbox bringing the name from the Page1 through the property named "myName" and second textbox which is also showing the name entered in the first textbox.........................

even i've mentioned all my code in my first request

Christian Graus23-Jun-08 21:06

23-Jun-08 21:06

you need to buy a book on C# and one on ASP.NET. You plainly do not realise that where you call your code, can make a difference. It can.

The issue is, the control is null. If you don't want to work with us to work out why, then we can't help you

You can also get previous page's control value by using findcontrol method.
You need not use property.

for example

txtName.Text = ((TextBox)PreviousPage.FindControl("txtName")).Text;

Yeah, but FindControl is a hack, surely ?
