Asp.net - Get User Control Property After Server Transfer?

Apr 14, 2011

I have a host page with multiple user controls in it. Some of these controls have a user created property named Enabled, and is boolean.In some controls the default value for Enabled is set to False. In the host page, I am able to access the property and set it to True. The control does what it is supposed to.On this host page there is a "Run Report" button which executes a Server.Transfer to a "Results" page.In the codebehind of the results page, control values from the PreviousPage are checked via other user created Properties for the controls and added to a ParamterList.

I am attempting to check the Enabled property of the controls on the PreviousPage, however when this is done, it appears that the Enabled property is set to that of the default (in this case False), and not what I had set it to on the page when it loaded.Does the value of this property need to be put into a hidden text box or something so its value is available after the ServerTransfer? It seems like any control which contains a value is retrievable via the PreviousPage and its user created property, but any variable set inside of the control is reset back to its default value.

C# - Server To Server File Transfer Without Any User Interaction?

Feb 16, 2011

In my scenario, users are able to upload zip files to a.[url]....I would love to create a "daemon" which in specified time intervals will move-transfer any zip files uploaded by the users from a[url].....From the info i gathered so far,

The daemon will be an .ashx generic handler.

The daemon will be triggered at the specified time intervals via a plesk cron job

The daemon (thanks to SLaks) will consist of two FtpWebRequest's (One for reading and one for writing).

how could i implement step 3?

Do i have to read into to a memory() array the whole file and try to write that in b.example.com ?

How could i write the info i read to b[url].....?

Could i perform reading and writing of the file at the same time? No i am not asking for the full code, i just can figure out, how could i perform reading and writing on the fly, without user interaction.I mean i could download the file locally from a.example.com and upload it at b.example.com but that is not the point.

Using Background Intelligent Transfer Service To Transfer Files To Server?

Mar 20, 2012

I will use the Background Intelligent Transfer Service (BITS) to transfer files from a client (laptop) to a shared folder on a server within our local network.The problem is a very slow network bandwith, if we transfer a file, the other clients canīt work, all requests to other clients (application) or viewing internet pages needs a long time.My idea is to use BITS in my tool to copy/transfer a file from client to server, also I hope to get more performance for the internet requests.

Bind Property Of User Control To One Of The Parent Control's Fields?

Dec 30, 2011

If I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.

Asp.net - Server.transfer To Transfer Execution Of A URL

Mar 9, 2011

I'm using server.transfer to transfer execution of a URL to a dummy page which fetches information from the database. The trouble is that the master page interacts with the session.

global.asax:
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
' Fires at the beginning of each request
If Not (System.IO.File.Exists(Server.MapPath(Request.Url.LocalPath))) And Request.Url.LocalPath.ToLower

[CODE]...

Master page:
If String.IsNullOrEmpty(CStr(Session("SessionId"))) Then

Session.Add("SessionId", Guid.NewGuid().ToString)

End If

Page declaration: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="utilityCMS.aspx.vb" Inherits="utilityCMS" MasterPageFile="~/MasterPages/main.master" EnableSessionState="True" %>

Web.config snippet:
<httpModules>
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add name="HttpModuleAggregator" type="XPIdea.Web.HttpModuleAggregator,xpidea.web.common" />
</httpModules>

I'm getting an error :
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.

I should also mention that this same master page works elsewhere in the site. Session is used throughout the site as well (not just in the master page).

Display VB User Control Property In VS IDE?

Feb 4, 2011

I built a VB ASP.NET 1.1 Web User Control that contains several properties. I want these properties to display in the VS2003 IDE Properties window, for easy manipulation. However, none of the properties appear! How do I make them show in the IDE?I am a C# guy, and not very familiar with VB, so this is probably a no-brainer. Here's a property, including attributes:

Private _priceHigh As String = "2000"

Public Property PriceHigh() As String

User Control Datatype Property?

Feb 9, 2009

I'd want a text box that at design time the developer can set a datatype property so only a value matching that datatype can be entered at runtime (e.g. If we made the datatype property of a textbox an integer then the user could only enter numbers into that textbox)In additiion I need a further property to replace ".Text". .Text always holds the entered value as a string, I want the new property to contain what has been written into the textbox but as the datatype that has been selected at design time.

User Control Property TypeEditor?

Dec 18, 2009

I have created a control inherited from a label.I want to add some items to the control at design-time and use a property TypeEditor to set those properties. I have no problems creating my properties for values for the custom control itself, but how do I best get access to the items (in this case more controls) that I want to add to the control?Explained another way; take the ribbon control toolbar in Office 2007. It appears to be a "label" that hosts buttons as members of its controls collection.

Error While Setting The Property In User Control

Feb 20, 2012

I am using a user control using vb.net. It include the program to retrieve the values from database while giving the paramers. When I set the property from my main program i am getting an error "Invalid attempt to call Read when reader is closed." When i gone to the online help i got the message as follows "System.InvalidOperationException (.NET Framework 4)The exception that is thrown when a method call is invalid for the object's current state. InvalidOperationException is used in cases when the failure to invoke a method is caused by reasons other than invalid arguments. For example, InvalidOperationException is thrown by IEnumerator.MoveNext if objects of a collection are modified after the enumerator is created, or ResourceSet.GetString if the resource set is closed before the method call is made. If the method invocation failure is due to invalid arguments, then ArgumentException or one of its derived classes, ArgumentNullException or ArgumentOutOfRangeException, should be thrown instead.[code]

Setting Default Property Value In User Control?

Aug 24, 2010

I am creating a customised version of the ListView control and there are several of the properties that a ListView has that I would like to be set to a different value to the ListView default when a user goes to use my user control.

From what I've found there seems to be a number of people suggesting just set them in the constructor, but to the best of my knowledge that would just mean that the user would not be able to change the properties in the PropertyGrid in the VS IDE.I assume this is probably something extremely simple that I have overlooked.

Set A Property Of A User Control From Repeater Databound Data?

Mar 28, 2011

I have a user control inside of a repeater that is being bound by a sqldatasource. I get the following error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. EDIT: NEVERMIND Egg on my face. I was getting this databind error because I was binding it somewhere else in an effort to troubleshoot my real problem from last friday but I forgot about it.

WHAT MY REAL PROBLEM IS: The usercontrol is getting bound before the properties get set so it appears as if they are never set. When stepping through I see that they get on the property is hit before the set on the property is hit. For example if I put <%# EVal("Address_ID") %> before the user control I will see the ID displayed but then the user control will display an emptydatatemplate because it is being passed the ID of 0.

<asp:SqlDataSource ID="sqlFacilityAddresses" runat="server" DataSourceMode="DataSet" SelectCommandType="StoredProcedure" SelectCommand="SP_Facility_GetAddresses" ConnectionString="<%$ ConnectionStrings:Trustaff_ESig2 %>">

Strategy To Override Enabled Property Of A User Control?

Aug 5, 2009

I have a usercontrol with a picturebox and a few buttons related to it, such as LoadFromFile, Paste and Zoom (that last one pops up a new form). Is there a way to override the basic Enabled property of the usercontrol so that I can keep the Zoom button active all the time, while turning off the other buttons?

I realize there are 2 "obvious" replies. don't do Enabled=False, create a custom method. do everything in the one form, not a usercontrol, so you can pick and choose disabling. Both are less than ideal, given that I'm putting this control into a couple of existing forms, so I'd like to work around how those forms already behave. So is there a way to override the behavior of my usercontrol when it gets disabled? What would be my best strategy?

VS 2010 User Control Property - Group Attributes?

Apr 2, 2010

this questions has be answered partially, but I can't find any full tutorial for this problem.I created my own user control (an advanced list with columns). Each column has different attributes like width, colour and text.I want to able to add this user control onto a form and select/edit the different attributes of each column. Hence, for each column in my user control (these columns are created beforehand, no columns can be added or removed from it) there should be a property in the property-menu. Each of these column-properties should be expanded (like the normal size-property in most default vb-controls that can be expanded with the little plus to show the width and height individually.What i mean by this, is: In the property-menu there should be attributes like Column1, Column2, Column3. Each of these attributes should be expanded to show the attributes like width or colour.

Currently I have different properties for different values of the same column, like Column1Wodth, Column1Colour, etc, but I want to group this under one value Column1.I think this is quite an easy solution, but forgive me, I spent more than 4 hours on google, but couldn't find a proper solution.

Building Custom User Control - Default Property Of Class?

Jan 22, 2012

If we say blue is the default colour of the Backcolor property I understand it as if you don't specify a colour for Backcolor blue will be its colour. But I could not make sense of default property of a class in the context of building a custom user control. After calling an instance of a class we have to either call one of its members or assign an other object for it. Therefore why should there be a default property?

My goal is that as soon as any character is pressed in the textbox, Listbox's item which starts from that character should be selected. I have done all the coding needed for the functionality but my problem is that when I add this usercontrol to my form, I should be able to change the DataSource, displaymember and valuemember properties at designtime. But I cannot see these properties when I add the control on the form.
