I am having trouble trying to access a UserControl I created and placed inside the EditTemplate of the ListView. How is it done? I've tried to access it at the ListView's ItemDataBound, ItemEditing and Databound with the following code with no luck:
ucEditTask = DirectCast(lvTimeEntry.FindControl("ucEditTask"), UserControl)
I have a ListView showing just a list of concatenated strings obtained from different field of the objects of the datasource.
A LinkButton (with CommandName="Edit") in each row Event handlers for OnItemDataBound and OnItemEditing
A UserControl in EditTemplate.
Now the problem is, I don't know how to use Bind expression in the UserControl. I mean, how to populate this usercontrol when the linkbutton is clicked? (I tried capturing the control in theOnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)

In almost all cases, my edit template and insert template in the formview are the same.
So instead of copying pasting the same markup, i decided to put it in a user control. The display works fine, however, the databinding doesn't work anymore. It works fine if I put the markup directly in to the formview template.
I have a UserControl inside the ItemTemplate of my FormView and I need to access it in order to get an event fired off. As the UserControl is inside the template, my event cannot see it!
View 4 RepliesI have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?

View 4 RepliesI am developing web application using asp.net. Here i need to access two databases in which one is present on other server. I am able to connect to database present in same server but not with database present in other server.

View 5 RepliesI have a DetailsView where EditTemplate has a dropdown where the datasource is a view from SQLDatasource.
SELECT DIR, NAME, TYPE,
CASE WHEN [Dir]=''then [NAME]+' ' + [TYPE] else [DIR] + ' ' + [NAME]+' ' + [TYPE] END AS FULLSTNAME
FROM vROADS
In the DetailsView, Data Source configuration Wizard dialog box, I select the SQLDatasource as the data source. Under "Select a data field to display in the DropDownist:" I select NAME. Under "Select a data field for the value of the DropDownist:" I select FULLSTNAME.
When I try to edit I get the error saying "... it is not in the list...".
This is what I am trying to make it happen: The dd list displays the [NAME] data and when the user selects a value from the list, [FULLSTNAME] is actually selected, displayed in the text box section of the dd and is also stored to the database.
Any way of making this happen? I think I get this error because, FULLSTNAME is not a part of the database, but it is in SQLDataSource as a field.
Let me know if you need the html code.

I figured this wouldn't be too difficult to do, but I can't seem to figure out how to do it. Is there a way to easily access the current item from a ListView data source? For instance, you can easily evaluate the current item's properties using Eval("propertyName"), but is there a way to access the object itself?
And if this isn't possible, what I ultimately want to do is get the Type of the object.
