C# - How To Create A User Control For This Kind Of Display With Databinding As Well
Jul 20, 2010
How to create a user control for this kind of layout. I have a css. But dont know how to create a control for this kind of display. Title is the department name and below mentioned radio buttons are status for each department. Now department can be multiple as present in database. This one box can contain only two department list and new box needs to be created as soon as 2 departments are filled into this. How can I create user control for this type to bind it from datatable. I am reading about DynamicDataField but seems to be of no use. Here fields encircled is department and its statuses

is it possible to create kind of widgets that are pluggable in ASP.NET MVC? I'd like to give my users the option to upload and attach a widget that I provide (ie. zip format). Recently I thought about deploying Areas in different project assemblies. Is it still possible with MVC RC2 (later RTM) and is there an option to dynamically attach that areas (say from a admin panel)?
Second question, how would you guys create a dynamic layout where admins could select widgets to display, arrange them, disable, move them etc.? I mean a flexible layout that can be changed via the admin panel without having to touch the code. Here I thought about defining and storing layout widgets paths in a db. Later I could associate these widgets with routes (in db). For each request (controller, action) I would fetch the layout among with associated widgets and output them recursively. Probably I could user RenderAction and PartialViews for that.s my direction correct or should I focus on some other technique?

I used the Create User Control to make a new user.
Is there a similar tool (I did not see one) that allows the user to edit their own profile?
If not what is the best way to do it? I have created user tables in AWAT.

How can I get all the textboxes inside a create user wizard control using getElementsByTagName().
Below is my JQuery code:
[Code]....
The above code isn't displaying hint text when the textbox retreives focus.
I think there is something wrong with this getElementsByTagName("asp:TextBox"); , I have also tried getElementsByTagName("TextBox"); , getElementsByTagName(":textbox"); and getElementsByTagName("input"); .
But no one of them gets the textboxes array.
Can anyone tell what will be the correct syntax for getting all the textboxes inside a create user wizard control using getElementsByTagName()?

Quick question here. I'm sure it's possilbe, just can't get it to work.
I've got a gridview. In have a gridview. The gridview is bound to a list of my custom class. The class exposes a link to an image as well as the image's height and width. I have a Image Control in the gridview. I've bound the Image Url to the correct property. Now, I'd like to bind the height and width properties as well. But everytime I do that I get the following error:
Cannot create an object of type 'System.Web.UI.WebControls.Unit' from its string representation '"<%#Bind("GetImageHeight()")%' for the 'Height' property.
Here is an example of the tag:
<asp:Image runat="server" ID="imgProduct" ImageUrl='<%#Bind("ImageUrl")%>'
Height="<%#Bind("GetImageHeight()")%>" Width="<%#Bind("GetImageWidth()")%>">
</asp:Image>

I was wondering about some best practices for data binding in web forms. For example we have a control:
public partial class MyUserControl : UserControl
{
public override void DataBind()
{[code]...
If we wanted that control to bind its data automatically we would do something like this:
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)[code]...
In the first section of code if we do our data binding before the call to base.DataBind() (#1) then that means that, if for example we databind a ListView, we don't have to call ListView.DataBind() because when we call base.DataBind() on our control it recursively calls DataBind on all child controls. Also, we won't have access to any of the properties of the control that were assigned to it using the data binding code blocks <%# %>
If we do our binding on our controls after base.DataBind() (#2) then this means that DataBind is called on these controls twice. Once when base.DataBind() is called, and the second time when we are forced to call control.DataBind(). I can follow here that I don't know about?
EDIT: Looking at this page:
http://msdn.microsoft.com/en-us/library/w5e5992d.aspx
Use this method to bind data from a source to a server control. This method is commonly used after retrieving a data set through a database query. The method is primarily used by control developers; most controls perform data binding automatically.It appears that best practice is to bind controls data automatically. Databinding is for when we explicitly set a data source.

I know how to use ITemplate to create a user control where it looks something like this:
<cust:control id="" runat="server">
<template>
random content...
</template>
</cust:control>
however, i am wanting to make a menu like control, and need a more specific setup. i dont need a template section, however, i want to create something where the user control can have only certain elements (which are also user controls). the best way to describe this is by example i think. this is what i want to create for my user control template:
<cust:control id="" runat="server">
<cust:contolItem id="" runat="" blah="" blah="" />
<cust:contolItem id="" runat="" blah="" blah="" />
<cust:contolItem id="" runat="" blah="" blah="" />
</cust:control>
the outer control is a user control, and inside its tags it can have other user controls (limited to what is defined in the outer controls code). all of the 'children' in the outer control would then be rendered on the outer controls page markup as if it were templated.

Hardware involved:
SQL Server 2000
Microsoft Server 2003 with IIS6 [code]...
The goal, from internal department (user) perspective:A department wants to "upload" an excel spreadsheet of data (product, term, rate, etc) to SQL (this will be from the internal network). The data is then saved to a webpage location for that department to view and approve. Once "approved," this data is displayed on the live web servers (public-facing website which is two load balancing servers).
Bonus:
The .NET application/SQL Server can send an email to the department reminding them to upload the latest rates (each weekday morning, then each Thursday afternoon) if rates have not yet been "approved."
From the development perspective, this is my general idea, but I may be wrong.There are three spreadsheets, each with one tab. The first spreadsheet is uploaded, and the .NET application puts it in a SQL table. I then need to display this table of data on a .aspx page for the department to approve before the .aspx page is pushed to the live web servers.
First, I need an interface for this department to upload Excel files. I need this application to save the data to SQL and display it in a .aspx page so that the department can look it over and approve it. The department needs a way to "approve" the page, and this action will push the data to the live web servers. Will this involve SQL data transformation services?

I'm starting out learning some ASP.Net programming and I'm going to be making a little community website for my friends and myself.
I was thinking of having a usercontrol and have that 'loginBox' shows the appropriate textboxes and login button, but also show his username when he is logged in.
Do you think I should handle this as a user control or am I missing something as an ASP.Net newbie?

I know you can can do this using MVC. But not sure if you can using Web Forms.
I have a button, when clicked it will get the data then populate a repater then injects the data to other controls. This works fine using postback, but it's a little slow and I want to do it using Ajax.
Is there a way to use JQuery to instantiate the repeater control or the user controls without using postback or using evil update panels?

I have a master page that holds the loginview content that appears on all subsequent pages based on the master page. i have a username control also nested in the loginview to display the name of the user when they are logged in. the code for the loginview from the master page is displayed as follows:
[Code]....
My authentication works perfectly and the page gets redirected to the designated destination. However, the login view does not display the users name. i actually cant figure out how to pass the users name that i had picked from the database to the login name control to be displayed.
taking a close look i also noticed the logout text that should be displayed after successful log in does not show. that leaves me wondering if the loggedin template control on the masterpage even fires at all or its still the anonymous template control that keeps displaying.?

I have a user control that's got an image ..when I added it to a page that doesn't have a Master Page..the image was getting displayed alright but when I added the same user control to a page with a Master Page.the image vanished!....When I checked the Page source the image's path was there like this. style = "background-image: [url] Image exists too! not that its gotten deleted or whatever.
Now idk where I read this but I did somewhere that when master page's added and user control's used..the ID s get changed or something..not sure..idk..if that's so..how on earth do IDs get changed and why and of what ? I just can't figure out what might have gone wrong..How do I test it?
[EDIT]
I checked the Page Source minutely again and guess what some div tag IDs have changed! ..I got this one div who's ID is "div1"..inside of this div is my Sprite image..now this "div1" is being changed to
...."ctl00_ContentPlaceHolder2_ctl00_Banner_ctl00_ContentPlaceHolder2_ctl00_Banner_div1"
Banner is variable of type UserControl declared in my test page(I am adding UserControl in code behind)...some more Div's IDs are being changed in a similar way...now what do I do about these changing IDs?
