Forms Data Controls :: Filling Web User Control From Web Form Page
Mar 4, 2011
I have a Web User Control that is sitting in a Tabcontainer on a web page. The user control is on tab 1 and has a listview control in it. In the listview control I have a textbox called txtWorkOrderID. In tab 2 I have a gridview with a button in one of the columns. When the button is clicked I want to grab the ID from the row I'm on and fill the txtWorkOrderID with it on tab 1. I've got things to work as far as grabing the ID and switching back to tab 1, but I keep getting a null reference when I try to put the value into the txtWorkOrderID which tells me its not finding the control. I am using .netVB in VS10. how to reference the textbox in the control on tab 1. here is what I have so far. [Code]....

I have a Web User Control I created for authentication. The web user control is inside the box below. Clicking any button (1 or 2) below works correct as it goes to the correct c# button click event in the code behind file. If I press enter on fields a or b it goes to the correct callback (button1's) if I press enter on field c it still goes to button1's callback, not button2's
How can I give my web user control a nice self contained for and view state etc, so it wont mess with the remainder of the page's form?

| User: __a___ |
| Pass: __b___ |
| [button1]|

Prompt:______c______ [button2]

Let's say I have a pdf form file available at website which is filled by the users and submitted to the server. On the server side (Asp.Net) I would like to merge the data that I receive in xml format with the empty pdf form that was filled and save it.
As I have found there are several possible ways of doing it:
Using pdf form created by adobe acrobat and filling it with itextsharp. Using pdf form created by adobe acrobat and filling it with FDF Toolkit .net (which seems to be using itextsharp internally) Usd pdfkt to fill the form. Use pdf form file created with adobe livecycle and merge the data by using Form Data Integration Service

I am looking for a simple (or best practice) way of pre filling some of the fields in a create form. As an example, say the create view is loaded for a model that has a datetime field. I want the textbox for that field to be filled with DateTime.Now. I don't need a javascript watermark or anything like that, I jsut want to pre fill the text box.
The GET version of my Create method in the controller just returns the view with no model so I am not sure where to set this value.I've beel trying to figure this out for a while and I must be missing something, I expected this to be really easy.

I have a set of images which needs to be displayed horizontally on the page. When the set of images reaches the edge of the browser window, they need to continue being displayed horizontally even if it means a horizontal scroll bar is made (In fact it will almost always result in a horizontal scroll bar forming).
I have tried to find some way to get images to push of the side of the page but can find no way (using basic CSS) without defining a width on a container holding the images (eg. 8000px). This is not possible as the width is dynamic (more or less images may be displayed as they are added to the database)
So my solution in theory:
I now record the dimensions of the image in the database when it is uploaded to the server. Using a repeater, if I add together the width of each image as they are loaded then I can use this number to define the width of the container. Seems to make sense right?
The problem comes when I load the images. I am not great at using the Repeater at the best of times and once again it has got me stuck. I have used the Repeater ItemCreated in my code behind but my variable which I declare (dim i as integer = 1) appears to get reset each time.
When I tried in Repeater OnLoad it didn't seem to work either.
The scenario in question can be found here: [URL]
You can see I have responsed the variable in the top left and they are all 1, hence why I believe the variable is being reset.

In a webform I have two textbox (txtDNI and txtAPE), 2 buttons (b1 and b2), 1 gridview (myGV) and 2 functions (dt1 and dt2) that return a DataTable txtDNI will be a parameter for dt1 function and txtAPE will be a parameter for dt2 function
DNI [_______] (b1)
APE [_______] (b2)
[NOM |APE |DNI |DIR |OCUP ]
============================
[ | | | | ]
[ | | | | ]
[ | | | | ]
[ | | | | ]
============================
[ 1 2 3 4... ]
When I press b1 myGV will be fill with the dt1 function's datatable and when I press b2 myGV will be fill with the dt2 function's datatable myGV allows paging=true and when I press the next index (2 or other) It appears a PageIndexChanging error. So the pagination isn't automatic and I have to code the PageIndexChanging event When I use a ObjectDataSource and I connect it with myGV the PageIndexChanging error dessapears and the pagination is automatic The problem is the ODS only have a one selectfunction (dt1 or dt2) but not both and the configuration is on design time
The same happen with the PageIndexChanging event where I fill myGV again (with dt1 or dt2) and set the new index (myGV.PageIndex = e.NewPageIndex) and What is the problem?? ... the problem is, for example, when the user erase txtDNI and change index of pagination ... the PageIndexChanging event is fired and call the dt1 function but the txtDNI(parameter) is empty and occurs an error, the function returns an empty datatable and myGV is empty too for avoid this I create viewstates variables for each function, so I have a 2 viewstates and fill them when the user press b1 or b2 When user press the pagination, the PageIndexChanging event catch the viewstate variable and convert it into a datatable and the problem of the automatic pagination is controled The problem is I don't have 1GV in the webForm I have 5GV in some pages... and I try to avoid...
1. all the code in the PageIndexChanging events of each GV in the webform.
2. use the viewstate variables

i'm having this issue, in ASP.NET MVC 2 where I'm adding a drop down list on the master page and filling it with data from an abstract master controller. When an option is selected an submit button clicked, it reroutes you to a new page. so lets say
the page lives on http://domain.com/landingPage i'm on: http://domain.com/landingPage i select option and submit takes me to
http://domain.com/landingPage/Projects/FramedPage i select again and now the post tries to go to:
http://domain.com/landingPage/Projects/landingPage/Projects/FramedPage because of the action="" i have set on the form tag.
MasterPage:
<form method="get" action="landingPage/Projects/FramedPage">
<%= Html.DropDownList("navigationList")%>
<input id="navSubmitBtn" class="btnBlue" type="submit" value="Take Me There" /> [code]...
The problem i am having is that if I am ON that page

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.

I need a GridView with 6 columns, one of which ("ItemID") is a HyperLink who's URL and text is determined from the C# code as I will get that data from an SQL database
INITIALLY, what I wanted to do, which would have been easy as pie, is:
[Code]....
HOWEVER, this does not work because every row in the Item ID column is filled with "System.Web.UI.WebControls.HyperLink". Apparently, this is what the HyperLink's toString() method returns. Apparently, you can't just throw a HyperLink into a DataRow and call it a day. I need to know how to make this ItemID column into such a HyperLink. It doesn't necessarily HAVE to be a HyperLink control, it just has to be able to call my javascript function on the aspx page, "popUp(URL)"
To give you a visualization of what I'm trying to achieve: this is a change log for an inventory system. The ItemID column indicates what item was altered. However, simply just having a number there doesn't say much, so I'm trying to create a link with the text, for example, "42 (motherboard x)". In other words reader["ItemID"] + " (" + reader["Description"] + ")", and that link will run a javascript function I have called popUp(URL) which takes a URL and opens it in a new window of specific size and location, to view that item's details.
I've tried various other methods such as disabling AutoGenerateColumns and manually create a HyperLinkField, but to no avail, because I couldn't get it to run my javascript function that way.

I need to create a display grid of picture cells 5 columns by rows determined by database select. Each cell to contain picture, title, name, phone number pulled from database. How do I create a table like structure and populate it? Can a DetailsView control be called into each table cell with the table row count being determined by the same select statement?
