Is it possible to display the result of a function instead of the value of a property in a DetailsView Field?
<asp:Label ID="m_LabelPlantCode" runat="server" Text='<%# Bind("PlantCode") %>'></asp:Label>
<asp:Label ID="m_LabelPlantCode" runat="server" Text='<%# Bind("PlantCode(true)") %>'></asp:Label>
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.

I have a Details view containing a 2 fields. A Name and a phone number.The Name field is a template with a dropdown list that's popuplated from a database table of Names and Phone numbers. The dropdownlist shows the names. When the user selects a name I want to put the phone number into the second field in the Detailsview.
View 1 RepliesI am accessing a DetailsView from the following event
public void dvDetails_DataBound(Object sender, EventArgs e)
I am casting the sender to my detailsview like so
DetailsView dv = (DetailsView)sender;
Now when I look in "dv" I can see the DataItem property has the data I want in it under a field name, but I dont know how to write the code access the value??
The field name is shown in the dataitem property as "_DTMON_F", I tried to say
Datetime myDate=dv.DataItem["_DTMON_F"]
BUT C# doesnt like the syntax
I am using entity framework 4.0 to bind a database object to a DetailsView on an ascx control. Within the DetailsView, I have a number of asp:panels that I'd like to show/hide depending on what's happening in that person's visit.
So, the first time through the page I'm setting panelA.Visible=false in the FormView_OnLoad event, and all is well - that panel is not output in the HTML. It listens to what I'm asking here.
Once I click submit and postback, I am again checking what's going on and setting panelA.Visibe=false in both FormView_OnLoad and EntityData_OnUpdating. But this time, when the page comes up panelA is showing.
I find that I can only hide that panel after postback by setting visible=false in DetailsView_PreRender, or by binding visibility to a public variable.
I'm thinking perhaps in the life cycle the DetailsView is binding again way toward the end, and throws away my visibility settings, even though they're not bound. So to show/hide panels within the DetailsView on postback, will I always have to set visibility on DetailsView_PreRender or after?
Am I on the right track here, or is something else resetting me at the last second?
Why can I set visibility the first time through the page but not postback?
I have developped a usercontrol, but I can't seem to find how to databind on a property of the usercontrol in a detailsview.The property is defined this way:

I use DetailsView to insert rows in database. Row has fields id, subcategory_id etc. I want to fill dynamically dropdownlist ddl_subcategories, which is used in TemplateField. Selected item value of first dropdownlist ddl_categories is used as parameter for generating collection for ddl_subcategories. I try it with using UpdatePanel, but method DataBind returns error "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.".
There's code of web form

When I click to edit the First Name, the field Last Name als goes into Edit mode. I just want the field where I clicked the edit button that goes in Edit mode.
am having a class which contains user defined data type property. I have created an instance of that class. When I bind that object of that class to DetailsView it is showing all properties except user defined data type property. Here is the sample code.

public int Age { get; set; }
public Address CustomerAddress { get; set; }

I would like to show the title and the price of a movie in my Gridview. The title and price are properties from the class Movie and Movie is a property of the class CartItem. Here is the Code of my gridview

<asp:BoundField DataField="Title" HeaderText="Title" />
<asp:BoundField DataField="Price" HeaderText="Price" />

Apparently the GridView shows only first level properties, but how do I show these second level properties.
I am using a detailsview to show a record from the database for editing - or for inserting a new record. When a checkbox in one of the fields is changed by the user I want to hide another field. To avoid unnecessary postbacks I want to use javascript. Here is a simplified version of what I have so far:

I have been able to select the "txtPromoCode" textbox and hide it, but it leaves the headertext. I want to hide the whole field.
I would like to know how can I easily customize my detailsView that when it is in Create mode ID field should be invisible I can rememebr that it was sth like visible = <% code here ... (IsCreated ??) here is an example:

I have a master-detail page, in which I use GridView to display multiple rows of data, and DetailsView + jQuery dialog to display the details of a single records. only one DetailsView is open at a time.
I need to be able to pull out a single field of the open DetailsView, for manipulation using JavaScript. Is there a way to give a unique ID to a given field in DetailsView, so I can use getElementByID? Or is there another way to accomplish what I'm trying to do?
I need to bind an ASP.NET control something like so:
<asp:label ID="lblName" Text=<%# GetName()) %>
and in CodeBehind file I have this method:
protected string GetName()

Is this right, or how I can do something like this?
I have several controls on a page that I want to bind the enabled property to a couple of properties in code behind that are set on Page_Load. Here's an example of what I'm using to bind to the properties.
Code:
<telerik:RadComboBox ID="AssignToRadComboBox"
runat="server"
[code]...
This works fine once the page is posted back for the first 4 controls on the page.Here's the 1st control that doesn't get disabled like I expect it to. The expression is the same in the Enabled property so I'm not sure why it isn't working.
Code:
<telerik:RadComboBox ID="CategoryRadComboBox"
runat="server"
Skin="Web20"
Width="225px"
Enabled='<%# IsAdmin && !IsCompleted %>' />
I've got 2 problems with this approach:
1. I need it to happen the first time the page is loaded rather than after a postback.
2. I need it to work for all of the controls on the page having the expression.
It's too late in the development process to rewrite the page so I can't use jQuery & knockoutjs for example to do this all on the client side.
I have a Hyperlink control in an ItemTemplate inside of a DetailsView. The DetailsView is inside a view of a MultiView which is inside of an update panel.
I am using binding syntax to bind the NavigateUrl property of the Hyperlink. However, the text shows up but when the mouse point moves over the hyperlink, the pointer doesn't change to a pointer hand like it should. And, nothing happens when the HyperLink is clicked. Here's the syntax I'm using:
<ItemTemplate>
<asp:HyperLink ID="hlWODWorkSpace" runat="server" ToolTip='<%# Eval("WorkSpace") %>'
NavigateUrl='<% Eval("WorkSpace") %>' Text='<%# Eval("Workspace") %>'
Target="_work">

</ItemTemplate>
I can't seem to reference a control properly, so that I could then change its properties. I have 3 fckeditor controls specified in edittemplate fields, but i only want to diplay them all if the querystring equals 1. so i created in aspx.cs file: {
View 4 RepliesSay I have a DetailsView with a bunch of fields, and I want only certain kinds of users to edit a few of them. They're too few to split them into another DetailsView, so what I'm thinking is to find some way to only allow a user to edit them based on some code-behind logic, effectively making them read-only at will.
I feel it's important to mention that the fields are both TemplateFields, not normal BoundFields with ReadOnly properties. For some reason the required functions don't jump at me from reading the documentation. Oh and I need eveyone to see their specific values, I just want to restrict edit access to them.
I have an ASP.Net detailsview control. Its DataSourceId varies and I set it in Page_load accordingly... (based on LLBLgen sub types, but this is not too important)I guess this is a page lifecycle leaky abstraction I am not "getting".The problem is that I bind to fields that may or may no be there depending on the datasource...To "disable" a bound field under certain conditions I've tried wrapping the bound field in a panel which I set to visible or invisible in code-behind, but I still get the following error:Sys.WebForms.PageRequestManagerServerErrorException: DataBinding: Entity does not contain a property with the name 'FilePrefix'.I change the detaislview.datasourceid in pageload...might be too late in lifecycle.I don't want to bind to that field, as it doesn't exist for the new datasource, but it tries to do so none-the-less and I get the error.[Edited]: Code as requested...ASP, detailsview bound column:

I have a json service method that returns an object with two properties. The first property is called Rows and contains the list of objects I want to bind to the dataview.

I have build a usercontrol in asp.net, and there is a property like the following.
Everything works fine when the bound value is an integer. However, if the bound field return a null from database, it will return a invalid cast error.
change to a nullable int is not desirable because it changes the how programmer work with the control's property in code-behind.

How to bind property visible?
Let's say I have a DataGrid that looks something like:
<asp:DataGrid ID="SomeDataGrid"
runat="server">
<Columns>
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="Data"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
In this Grid, I set the datasource to some collection that contains a public property called "Data" and do a databind(). Every works as expected.Now let's say I want to set the DataField attribute of the column to a public member, or a property, or some other thing I've computed. What is the easiest way to go about this without creating intermediate objects or adding public properties to the objects in the collection?So what I want to do is something like:
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="someMethod()"></asp:BoundColumn
