Asp.net - Getting Form Field Names On Submit When Form Is User Control?
Nov 28, 2011
I've created the beginnings of my new web application, but I am often coming up against the issue that ASP.NET renames elements IDs or in the case of form fields, their names.I have a form which is basically a sales system. It is essentially made up of two User Controls, one is a form for Customer Details (name, address etc) and the second is a form for the customer's purchases, it consists of a number lines dynamically created by Javascript created as you list the items the customer is purchasing. Both these sections are User Controls because they are to be used for other areas of the system where this data will need to be recalled/re-entered.
When the USer Control is loaded, the field which contains the Customers' Name is renamed "m$mainContent$customerForm$name" I understand where this comes from, "m" is the ID of my Master Page, "mainContent" is the main Content Placeholder and "customerForm" is the name of the User Control.In fact, in my case, this will always remain the same on all forms, so it is relative easy to overcome... but... suppose it wasn't I can see there are ways I could deal with this with Javascript, but the form doesn't need an AJAX submit, a normal Post will do fine for this, so when I open up the recieving page I want to call Request.Form("name")% to save the customer's name into the database, but of course I really need Request.Form("m$mainContent$customerForm$name")% How would I dynamically extract those prefixes from the posting form to ensure that if I rename anything or use it in a different scenario, the problem will not break it?

Basically, I have created a search facility which is housed inside the navigation control on every page. My predecessor set every single page up enclosed in a form for postbacks.
I need these postbacks to continue working however I need the search when submitted to post to go to a separate page and post the data. I tried various methods such as "postbackURL" on the ImageButton but it didn't do anything.
Below is an example of my form code from my navigation.ascx control:
I have a webbrowser and on a form I need it to fill text. The problem is, in order for the submit button to activate, you have to atleast type in 1 letter for it to update and make it send. The problem is when I do document.getElementById("p1").innerHTML= "SSSS" it works but it wont update the submit button to allow me to submit the form. What should I do?
I am trying some Uiculture change functionality. In that I need the name and text of controls in a form to change the culture. I got some Demo project and it is in C#. I tried to make the same functionality with the C#.net and Also using VB.net. But the below mentioned code returns control name with an underscore as prefix. But I don't want underscore. Code is actually written in Class library. It works perfectly in C#.
Code is written below Dim fields As FieldInfo() = form.[GetType]().GetFields(BindingFlags.Instance Or BindingFlags.DeclaredOnly Or BindingFlags.NonPublic)
I have to use Form.Action to redirect to a script that will be picking up values from my page. It is worth noting that this script is external.My issue is that I also want the button that is clicked and has the Action hooked up to it, to also complete some functionality in the code behind first.Is there anyway I can either :In the buttons click event handler, can I set the Form.Action and then call something such as Form.Submit?OR Set up the Form.Action in advance and then somehow have the button posting back before the action takes place.
In the past, I used the code below to fill out a form field using the webbrowser control in VB.Net. The page I am working with doesn't have name field for the inputbox, so my code doesn't work. How would I fill out the input box defined at the bottom of this post in bold?[code]...
I have a DataGridView which populates from an SQL query just fine in default mode

How can i drag already created user control into a form? In a clear statement, i have created a user control. I need to use this user control 2 times and i need to drag it into a form.

I have a button on the main form which generates a new instance of the usercontrol in the flow layoutpanel of the currently selected tab of the tabcontrol.
Then I have a button in the user control meant to delete itself from the flowlayoutpanel.
I would like to make an application where there is no form, only controls, this way theuser can see what they are doing on top of their work. How could I for instance put a textbox on the screen, just like form1, but without it being a parent of form1, almost as if it was form1. Basically form1 is hidden.

I created a custom user control named "XYZ" and It is avaialble at the toolbox menu in the design mode and I can drag and drop it to a vb.net Windows form. What I really want is to dynamically to add this user control to the Windows form during the Windows form load event. Actually I want to add this user control to a "split container" named "sc_1" on the tab page named "tp_1" on a tab control named "tc_1" on a Windows form. What is teh vb code to add a user control to a Windows form. I am using vs 2005 and dotnetwork v2.0.
I make a user control with textbox. When user press enter and textbox doesn't have any text then a search form open. Search a data and select some think and return to main form where my textbox control insert. I write a code below :
If txtIsbn.Text = "" And e.KeyCode = Keys.Enter Then Frm_Book_Search.FormLoad = True Frm_Book_Search.ShowDialog(Me)
[CODE]...
But problem is that when Frm_Book_Search close and it must be focus in textbox but it not happend. when user close the frm_Book_Search form then not focus my application another software if open at that time it will be focus that software. if there is not open any software then it is not any problem it will be focus my application in my textbox. how can i write code to focus current form after close frm_Book_Search form.
I have created a user control with some properties but when I change them in a form and build the return to the default value, Here is the code I did: Public Property ButtonFind As Boolean Get Return CmdFind.Visible End Get Set(ByVal value As Boolean) CmdFind.Visible = value End Set End Property
I have created a User Control and would like to be able to detect when the user clicks on the Form.I have seen this question which is related but the suggestion to use the the Leave event doesn't always do what I want because the focus doesn't necessarily change when the user clicks the Form (my control could be the only control on the Form in which case focus stays with my control).I want to be able to do something like this from within the User Control:[code]
I have a "windows form" user control--that is, not on a web page etc. This user control has a form within the user control project. However, code from within the user control can't 'see' the form even though it is a public class---I don't understand why this is the case.
So how can I access the controls (a couple of radio buttons) on the form from code within the user control? I tried creating public properties on the form to return the state of the radiobuttons, but this still doesn't work. I get a "Reference to a non-shared member requires an object reference." error
Should I not be able to see the form since it is a public class?
I created a user control with a label and 2 combo boxes, and a public property called ControlDataSource that accepts a dataset - which it populates the combo boxes with. I added the reference to the VB project I want to use it on and to the toolbox. I was able to draw it on the form with no problem and use it. However, after changing the backcolor on the control and recompiling it, it is no longer seen by the form. When I bring up the form it's used on, I get a white screen with a bunch of xml. The problem seems to be in the designer, and I get an "object reference not set to an instance of an object" error. Here is the code from the designer:
[code]...
The reference error is pointing to the line: Me.UcDx1.ControlDataSource = Nothing
Here's the wierd part. If I hover the cursor over that property, it correctly identifies it as a dataset. So it does know what it is, but it can't seem to use it.
I have a Mdi form and I need to put a control on the form which the user can resize. Now I need a container can be dragged by user to increase it's size. The split container will not work in my case as I have childforms and stuff. I want a container whose size can be increased by dragging it on one side.
