I am displaying other elements on the page as well. Do you think the only way is to ship the Bitmap to a database as jpeg, and then read it back? Seems slow and counter intuitive to do it that way?
Ideas?
thanks

No, the only way is to have the image in your file system. So, your best bet is to store image paths in your DB instead of the jpeg data.

You can't do that. The browser will get the image in a separate request. You can't send it in the same request as the page.

Now I have spendt several days without finding a solution to my problem. I almost wish I still coded in ASP or PHP, this was easy in those languages. I have a product webpage where users can view product data for several products. And the users can aslo make changes to the selected product, change price, length and description. For selecting product I'm using a dropdownlist and a for saving data a submit button. As you see in the code below, I can't get the user entered data back from the page. The Page_Load event reload the textbox with data from the database on every reload of the page. Is it possible to construct a page that let me save the user entered data back to database, and not overwrite the text in the textbox on every reload? The code below is a simple, working version of my problem. The line "string sNewText = txtShort.Text;" should returne the userentered data, but it don't.
------------------------------ Design/Html-code ----------------------------------------
Choose product: <asp:dropdownlist id="ddlProductList" autopostback="true" runat="server">
Short text:
<asp:textbox id="txtShort" textmode="MultiLine" enableviewstate="true" runat="server">
<asp:button id="btnSave" runat="server" text="Lagre" onclick="btnSave_Click">
------------------------------ Code behind ----------------------------------------
protected void Page_Load(object sender, EventArgs e) {
int iIndex = 1;
if (ddlProductList.SelectedItem != null)
iIndex = Convert.ToInt32(ddlProductList.SelectedItem.Value);
if (!Page.IsPostBack) {
ddlProductList.DataSource = ProductManager.ProductsAll();
ddlProductList.DataTextField = "Title";
ddlProductList.DataValueField = "Id";
ddlProductList.SelectedIndex = iIndex - 1;
ddlProductList.DataBind();
}
Product productItem = ProductManager.ProductDetails(iIndex);
txtShort.Text = productItem.ShortText;
//txtShort.DataBind();
}
protected void btnSave_Click(object sender, EventArgs e) {
//string ret = Request.QueryString["txtShort"];
string sNewText = txtShort.Text;
}

You gave code to load the textbox in the Page_Load event which causes to lost the data. Is this the problem? Sorry if I misunderstood the problem

You should only do this once, i.e. when !IsPostBack.

I found the solution for my problem. I had to move the code for reading the selected products data/text from database into the Dropdownlist's "selected(?)"-event.

Hi,
My code looks follows for the asp:Wizard control:
<WizardSteps>
<asp:TemplatedWizardStep runat="server" ID="MyTemplatedWizardStep">
<ContentTemplate>
My Templated Wizard Step<br />
<br />
</ContentTemplate>
</asp:TemplatedWizardStep>
<asp:WizardStep ID="WizardStep3" runat="server" StepType="Complete">
Complete Wizard Step
<br /><br />
<asp:Label ID="Label1" runat="server"></asp:Label><br />
<br />
<asp:Label ID="Label2" runat="server"></asp:Label>
</asp:WizardStep>
</WizardSteps>
The button displayed on the TemplatedWizardStep page says "Finish". When I add my own own custom button in <CustomNavigationTemplate> then I am not sure what the CommandName property must be set to, because if I make it MoveNext then it doesn't function the finish button because I have an event handler with OnFinishButtonClick. It does not fire if I have my own button here.
Please can someone advise.
Thanks

I want to show a popup window on while clicking a link button .i want to pass the url of the popup window and also the id of each record while Databinding.the code which i used as follows.
Javascript as follows
function openWindow(url) {
window.open(url,'Calendar',
'width=500,height=400,left=200,top=250');
}
Link Button Postbackurl Code as follows
PostBackUrl="javascript:openWindow('<%# Concatcolumns("UserDetails.aspx?id=",DataBinder.Eval(Container.DataItem,"ID"))%>');">LinkButton
Concatcolumns Function as follows
public static string Concatcolumns(object obj1, object obj2)
{
return Convert.ToString(obj1) + Convert.ToString(obj2);
}
My Javascript code and Concatcolumns functions are correct only problem in my Postbackurl code.what is wrong in that.while page loading i want to bind each record id along with the popup window javascript.

Every thing seems ok. May be the PostBackUrl property makes the problem. Try an 'a' tag instead of LinkButton.

What does the generated code look like?
Why do you concat the url using server code, when you can just as well put it in the markup code:
PostBackUrl="javascript:openWindow('UserDetails.aspx?id=<%# DataBinder.Eval(Container.DataItem,"ID") %>');"

hi friend's
i want to load a page in a window that opened by javascript
but my problem is that in the requested page i write code to determine the url of the requester page,but when i open a window by javascript i can't determine the url of the requester page,in the other word:the value of "Request.UrlReferrer.AbsoluteUri" is null.
what can i do ???
my really question is:
how can i load a page in a window that has not scrollbar or menubar and the width and heigth value is constant,and in addition i can determine the requester page on the requested page?
nobody help you...
you have to help you yourself
and this is success way.

When you use the window.open method, the requested page has no requester. If you would use a link with target="_blank", the requested page would have a requester, but then you can't control the appearence of the window.
In Javascript you can reach the parent window using window.opener, but you can't reach it directly from the server code.
Why do you need the url anyway? What are you going to use it for?

I have built ASP.NET 2.0 application using Visual studio 2005.
I created it as a website with Http type on IIS(Localhost)(not File system which VS 2005 defaultly creates website).
Say my application name is Website1:
Root is : http://localhost/Website1
I am using Frontpage to move my website from local to weserver.
Issue: Tried opening my local website1 by using root http://localhost/Website1.
It defaultly opens LocalHost as website and Never allowed me to open website1 folder as website.
But it gets moved as folder 'website1' from localhost to webserver.that doesnt work.
I also saw on my IIS Website1 is a website(not just a folder).
I cannot understand, whats going on.Is there some things to configure...
Any kind of help would be appreciated.
Thanks in advance

u can easily deploy web sites by creating a website in web server and just copying files from local site to server using FTP.
or u can use Copy website option in Visual studio.
regarding ur prob,
when u work on local site, u will be creating virtual directory in IIS..
in server u will be actually creating website.. and u have to configure the website properties in IIS in the server
i think this will be helpful

if u are using report wizard, then u have option to get formatted colored reports in style tab of report wizard.
or u can manually do that by changing properties of report fields.

When you sort, change the html you generate to show the right image.
