I have tried with field value
<sc:fieldrenderer fieldname="field" runat="server"/>
I am able to get the field value but I need to access the section that contains number of fields
What is the way to achieve that?
Sections are only to get the fields organized so there isn't a control to render all the fields of a section, you have to render field by field.

We have required conditional file field that depends on another dropdown field. If dropdown field value YES then file field will show and added required option but if dropdown value NO then file field not show and remove the required option.
We have done the hide show logic in file field but not able to do required option on off. Can anyone please suggest how to do that?
Without the exact website link, it is difficult to explain perfectly. However, from what I understand what you need to do here is to implement a custom validation.
You can refer this link to understand how to implement custom validation.
Basic flow of code:
1. Give ID to the drop down so that you can bind an onchange event with it
2. Bind an onchange event that hide/show the file field
3. Create custom required validation which checks your drop down value and decides whether the other field is required or not
This should do your job... Feel free to ask other questions and post your website uRL and code to get a better answer.
I am using an ASP.NET Label control.
<asp:Label ID="LblDescription" runat="server">
LblDescription.Text="Html Tables or/and Texts"
I want to display the content of an editor to this field. My editor can contain text as well as tables.
So if I include labels, how can I display this table to this label? Because table is in HTML format.
I saved the data as nvarchar. So I can retrieve the data from database but I can't access the value in label.text field.
How is this possible? Or is there any other control that meets this requirement?
If you want to insert tables coming from the database, obviously a ´Label´ control is not the proper place due this control is rendered as a span.
You have, for example, the ControlPlaceHolder or the LiteralControl. If it is a regular HTML table, I will choose the second one.
I have a detail view control in my aspx form.
I have the following field in my detail view:
NameId
Name
ContactNo
But i dont want to allow the user to edit the "NameId" field.
So i set it as READ ONLY and INSERT VISIBLE.
But setting it dosent allow me to update.
If all the fields are set to be allow for editing, the update work successfully.
How should i go about doing it?
Are you trying to pass that NameID field in the UpdateCommand?
Setting the field to ReadOnly=True won't pass the value to the underlying datasource. So you may need to remove that field from the UpdateCommand.

I am slowly, piece by piece learning what I am doing with ASP.NET
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?
I am using .NET 2.0, so can't use Static Client.
This is really old but let's see if it's useful for you.
Getting this example I managed to get the value from a given field name without prefix.
I'm sure it is not the best solution, but it was useful for me. Let's say you want to recover the value of a field named "hfIdAviso", that comes in the POST as "ctl00$body$hfIdAviso":
var value = Request.Form.Cast<string>()
.Where(key => key.EndsWith("hfIdAviso"))
.ToDictionary(key => key, key => Request.Form[key])
.Values.FirstOrDefault();
That will return the value for that field.
Hope it helps.
If you include runat="server" in the declaration of your user control in the ASPX page, then you can access this control by just using the ID value of the control.
For example
In the ASPX:
<uc:MyUserControl ID="mycontrol1" runat="server" />
In the code behind (in C# syntax):
object foobar = mycontrol1.SelectedValue;
suppose you have a form inside user control that has a TextBox field with ID="txtfname".You have registered your user control in page1 and you want to POST form data to page2 :
in page1 you have user control:
<My:WebUserControl1 ID="myuc" runat="server" />
in page2 codebehind , you can get the value of user control form field (txtfname) this way :
string firstName = Request.Form["myuc$txtfname"];
I am building an ASP web site that contains a large section that represents a database front end. I need to build forms to manipulate the database and obviously there would be much repitition i.t.o the type of input field and rules pertaining to the field. For example there are many tables where I have take on varchar(n) fields that could be required or not.
I was thinking to build a set of custom controls that would contain a label naming the field, an edit control (text box for example) and validators for the edit control. The custom control should automatically get the field length and set the MaxLength property as well as determine if the field is a required one and ad a RequiredFieldValidator etc. So when I create the custom control I would do something like this:
<user:UserControls_TextFieldEdit LinqObjectType="Franchise" FieldName="FranchiseName" runat="server" />
There must be a way to achieve this but I haven't I been able to find any controls/libraries that do this. I don't know how to get the field information armed with only strings representing the Linq entity name and field name.
Any help/suggestions would be appreciated.
I am using ASP.NET 3.5 and Linq.
Thanks,
Gerhard
Is Dynamic Linq what you need?
