Dynamic Data Field template edits - Tooltip text, Dynamic Data Page template edits - field sort

Posted By:      Posted Date: October 20, 2010    Points: 0   Category :ASP.Net

I have an ASP.net website build in VB 2010 web dev pro using 4.0 framework.  Its a dynamic data site and I am having some trouble formating some of the field and page canned templates.

Q1: Field Templates - the tooltip code (TextBox1.ToolTip = Column.Description) is within the ascx.vp pages for each of the field templates.  Where can I update each columns description (as the code references) so the tooptip will be column/field specific.  If its not as straight forward as that, I was trying to write an if/else statement because the tooltip code is set at the field type level (decimal, date, etc) and I want it to be column specific.  example;

if column.value = Financial Impact

then  TextBox1.ToolTip = "enter financial impact in whole dollars"

else TextBox1.ToolTip = "next fields tooltip text"

ASP.Net Dynamic Data - DropDownList Field Template with AJAX Cascading DropDown Extension

Hi all,   Have spent hours trying to create a Dynamic Data Field Template holding a DropDownList which is extended by the AJAX Cascading DropDown extension. Final form holds multiple cascading dropdown boxes. User selects Country (Land) then Postcodes, Counties (Provincie) are populated. Once postcode is selected then towns (Plaats) are populated.  The problem I am now facing is that the viewstate for the dropdown lists is not being saved/restored after an insert action or custom validation error. So basically the dropdown lists are being reset to their default values. Some code (if missing parts, just ask and I will post them) - Don't mind the code structures etc... needs some refactoring :) Attribute I created:using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Data { [AttributeUsage(AttributeTargets.Property | AttributeTargets.Field, AllowMultiple = false)] sealed public class CascadingDropDownParametersAttribute : Attribute { //public string TargetControlID; // The ID of the DropDownList to populate. public string Category; // The name of the category this DropDownList represents. public string PromptText; // Optional text to display before the user has selected a value from the DropDownList. public string

Set up a validator that compare the value of the current field with an other (using Dynamic Data)

Hi! Most of it is in the title : I'd like have a validator on the DateTime_Edit template for example that allows to compare this field with an other DateTime field. My problem is when I am in the DateTime_Edit template of my "master field" (the one I want to check), how can I access to the other field given the architecture of Dynamic Data FieldTemplates? But perhaps I'm not thinking in a good way on this control. Any advice will be welcome. Thanks Raphaelp

dynamic template field order


I have the following example with adds a dynamic template field to my gridview.  However its being added at index = 0.

I need it at the end of the gridview, which has columns determined by user entry, so they will not always be the same amount of columns.

XML data stored in text field

Hi there, I need to extract XML data stored as text from any number of given rows of a table. The stored XML data typically looks like this: In the ATTRIBUTES field from NODEMEATADATA table <T41><A93>S46 SE Trade &amp; Investment</A93><A35>3284</A35><A84>28 November 2008</A84><A33>S Polkinghorn Bband</A33><A46>S46 0501-KEYF Keyfort Limited</A46><A89>400.68</A89><A90>0</A90><A88>400.68</A88><A66>560200 Broadband</A66><A70>ITAC</A70><A54>N/A</A54><A86 /><A87>Awaiting Posting</A87><A91>Mashudul Karim</A91><A94>Chris Burchell</A94><A92 /></T41> I need to be able to extract the invoice numbers from any number of rows based on a WHERE clause that referes to another column of a date/time format. The invoice numbers are with the <A35>****</A35> tags What I have noticed in the table is that element is not always the same. SOme are <T41> some <T6> or <T7> which I think might have something to do with the document status within the <A87> tags. If possible I need to pick up within multiple elements. I then need to add this to my current simple query: SELECT METAID, CONVERT(VARCHAR(10), CAST(CAST(CREATEDON AS VARCHAR) AS DATETIME), 103) AS 'CREATED', FROM N

How to use Page/Content Field data in a Navigation - how to include images in a navigation?



I look for a hint on how to accomplish the following:

I create a Internet-type of Site based on the Publishing Infrastructure/Features. The site is structured by subsites that are all based on same Masterpages and PageLayouts. In the PageLayouts there are the common fields like Title, Page Content, Page Image. And exactly the last one "Page Image" should appear in the navigation.

Searching the web pointed me to creating a custom PortalSiteMapProvider. In the GetChildNodes I figured out how to get the actual Url to the "Page Image" of a Node in the Sitemap. 

But here I'm stuck. How to I get this information (the image url) delivered to a menu control to actually draw an img src=...?The build-in Nodes don't seem to support such an additional property. And the build-in menu controls (asp:menu, sharepoint:aspmenu) neither.

What do I need to create to make use of the ImageUrl? A custom Web part? or ... ?

Any hints welcome


Thank you

Change Default Sort for Dynamic Data Web Application




I just created a dynamic data web application and setup a simple .EDMX file. Next, I created meta-data / partial classes to ensure that my integer identifiers wouldn't show up:

// ...


public object TableId { get; set; }

 // ...

I wanted to now set the up the list pages so they sort using a different attribute ("Name" in this case). Anyone know if this is possible / how to do it?

create a dynamic field in the master page (site.Master)




I'm starting with ASP.NET MVC (1.0). I have a problem to resolve.

I have developed a web applicaton (an application of articles like e-commerce) with a head (logo and menu). I have defined the head (logo and menu) in the Master page (site.master). Now, I must display the number of articles in the head in a field (like the number of articles in the virtual basket in the e-commerce).

I can read the number of articles in the data base (in the controller), but i can't integrate it in the master page.


Please help ?   

Can a Dynamic Data page update a View?



I just started working with Dynamic Data (asp.net 4, VS 2010 express, C#) and have tried to simplify the displaying/not displaying of columns by using a simple, single table, updatable SQL view.  Adding and displaying the view work and the in-line edit and update controls are there and seem functional but I can't access any of the columns.

Does DD not support updatable views or have I missed something?


Displaying data from Enhanced Rich Text field


Iam using a custom list, one of the column datatype of the list is Multiple lines of text with type of text to allow as Enhanced Rich Text. Users in my site can copy any type of data and paste in that list coulmn. I need to display the list data in a webpart same as how it is copied. But after querying the list iam getting all the Style tags. How to avoid this.

For example, i copied the following text in the coulmn as below:

One advantage of using the SPGridView control in SharePoint-based solutions is that it has been integrated with the cascading style sheets that are built into Windows SharePoint Services 3.0. Also, the SPGridView control is heavily.
But after quering the list while displaying, following is the output iam getting. How to avoid the tags:

Dynamic Data, Multiple Tables in one page?


Hi there,

So I have a Dynamic Data Project with a few custom pages that are not the standard list/insert/update pages. So I created my custom page, Process.aspx. It's a regular web form with a dynamic data manager, plus a LINQDATASOURCE. That works fine. However, inside of my main formview I'm going to have a subformview. So I set up a second LINQDATASOURCE, but it seems when I try and use Dynamic Data Controls inside of my sub form view, it can't seem to find the MetaTable, even though I set the subformview up with its own data source. Can I have two dynamic data managers somehow, one for each data source? I don't think there's a way to associate a dynamic data manager to a specific data source, as far as I can tell.

Or, can I do something like :

<asp:DynamicControl runat="server" DataField="Client.SubField" />

Any insight is appreciated!
