DevExpress Generates Thousands Of Lines Of ASP Code / How To Reduce The Code,
Nov 24, 2010
After insert a grid or any other tool into an aspx page it generates enough code for that tool(for ex.): <dx:ASPxGridView ID=ASPxGridView1 runat="server"></dx:ASPxGridView>...
But,after adding any property to this control (like Show group Panel) it generates more than 3000 lines of code in aspx page () and after adding any other tool the code is increasing in a enormous way...
How can I reduce the code, maybe there is a property(settings) in DevExpress option...

I have a DevExpress grid that needs to be refreshed every time the value in a combobox is changed. For example, I have a combobox that sets the grid's page size. One of the requirements is that the combobox does not cause a full postback.
The combobox is declared like this:
<asp:DropDownList ID="cboPages" AutoPostBack="false" runat="server"
EnableViewState="false" OnSelectedIndexChanged="cboPages_SelectedIndexChanged" />
On selected index changed, it sets a cookie whose value is the selected value. When the combobox value changes, a javascript function is called:
function PerformCallbackOnGrid(grid) {
try {
grid.PerformCallback("refresh");[code]....
The function is attached in code behind: this.cboPages.Attributes["onChange"] = "PerformCallbackOnGrid(" + this.GridClientID + ")";
After performing these steps:The user changes the grid page size using the combobox, so PerformCallback is called at least once.
The user presses F5(refresh).
The user tries to change the page size again.
an 'Invalid viewstate' error message appears.
I have tried setting ViewStateMode to Disabled for the grid, also EnableViewState="false".

I am using a sql server 2008 database and I am uploading images to the server using an asp.net webapplication. I have an image column that I use to store the images. I have chosen the database to store the image and not a folder on the server, because the database table will contain only very few rows. maybe close to 10 or 15 rows.
My question is, Do I have to reduce the size (dimensions and quality affecting size on disc in kbs) of the image in code behind before uploading it to the database or do I keep it as is. The total upload size permitted is 200kb. I am thinking that when the image size (size in kbs) is small my webapplication performance will not be affected when displaying them from the database.

So I am a beginner with .NET, Visual Studio, C#, etc. But I am wondering something about the code behind a form and a difference I am seeing in 2008 versus 2005. So lets say I have a simple Windows Form app, C#, and I throw a couple controls on it. Then I add some MessageBox.Show event handlers for the default events....in 2005 there is that little section within the code that is hidden that basically contains the code that 'registers' the controls with the system....I think. That may be a bad definition?? Basically I think that automatic code generated here just basically associates the event to the event handling code....anyway.
I can see this is 2005 (once I click the like gray box), but it does not appear anywhere in 2008. So this has to exist somewhere, and I just wanted to ask to be familiar with what is going on since I am new to this. I still have to figure out how to turn on the code line numbering in 2008, but I can google it.

The inline code
<% for (int i = 0; i < ThumbnailList.Items.Count; i++)
{ Response.Write("thumbnailViews[" + i.ToString() + "] = $find('" +
ThumbnailList.Items[i].FindControl("ThumbnailView").ClientID + "');
"); } %>
produces a bunch of compile time errors in Visual Studio 2008 - although it works fine.
But this seems to be the exact way inline code should be added, at least according to this MS help file:
[URL]
The errors are:
expected expression (at "<%")
expected ';' (at "int i")
expected ')' (at ThumbnailList.Items.Count;
expected ';' (at " i++)")
I have done a
<%@ Page Language="C#" ...
at the top of the file.

I have an annoying problem with Visual Studio 2008.
When I run the "format code" command ("control+k, control+d") -- it will insert a carriage return. How do I get it to stop doing this?
For example:
<label for="shipCompanyName">Company Name:</label>
undesirably becomes
<label for="shipCompanyName">
Company Name:<label />

I'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?

I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:
[Code]....
I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like
[Code]....
This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?

how to generate HTML code from the code behind?
I would like to build a form that generate an html code inside a for loop.
I will let the user enter the photo name and No. of photos
Then I will generate an HTML code like this:
<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />
depending on the No. of the photos the code will be duplicated in the loop
Then I will display the result of the loop in label or in a textarea to let the user copy it any where
The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses
