Forms Data Controls :: How To Access A Template Item In A Detailsview
May 24, 2010The Detailsview has a template containing a textbox for one of it's fields.When an item is selected in the Gridview, I want to set a property of the textbox. How do I do that? I've tried Findcontrol for the item during Prerender of the detailsview. I've also tried many other things. Below is a portion of my aspx code followed by my VB code.

Web Forms :: How To Programmatically Set Template Fields Label Value Two One Of Two Fields Returned In A Sqldata...
Feb 8, 2011 I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

Forms Data Controls :: Formview Insert Template Fill Like Edit Item Template For All Fields
Mar 3, 2010I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

View 1 RepliesHow To Apply A Regularexpressionvalidator To Selective Fields In DetailsView
Feb 11, 2011I have been having trouble with this for a while now. I have a bound textbox within a Detailsview, to which I have added a RegularExpressionValidator (REV). The Regular Expression used is [a-zA-Z]*
After running the Web Form, the Edit button opens the fields. Any entries made cause the REV error msg to be displayed when the Update button is pressed, irrespective of the validation. The Update button continues to be displayed until the Cancel button is selected and the original record is returned to the screen replacing any entries.
The RequiredFieldValidator works correctly.

Setting Values For Invisible Fields / Properties In DetailsView?
Mar 16, 2011I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If
But this returns an error of "Object reference not set to an instance of an object." how to accomplish this - either using the method above or another method? The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"

How To Handle Null Fields In DetailsView Control Bound To TemplateFields
Dec 16, 2010I am using the DetailsView Control to read a LastUpdatedDate field (which can be null until an update is performed) from the database. The LastUpdatedDate is of type DateTime saved in UTC. With the DetailsView control, I can use the NullDisplayText property of the boundfield to safely display an custom message. However, once converted to a template field, that property is lost. Now, how would I display that message if the field is null as I am also formatting the date for display to show in local time.

Forms Data Controls :: DetailsView Dynamically Suppressing Fields / Error 156
Mar 24, 2010I have a working gridView/DetailsView used as a member Lookup.
Some Fields in the Details View have data only some of the time, and when there isn't any, I want to suppress that row of the detail. No Go.
It seems that some of the function available in other controls don't exist so I cannot make the "field and its "header" Visible = "False"
FWIW, The control is nested inside a loginview control.
