Forms Data Controls :: Detailsview Not Updating If Gridview Not Visible?
Dec 14, 2010I have a master/detail page using a gridview as the master, and a detailsview as the details. The gridview is set to select a record, and the detailsview picks up the ID and you can either edit that record, or add a new one.The detailsview is set up with various template fields, and if everything on the page is visible, it works OK.However, I wanted to hide the Gridview when the user in working with the detailsview. But if I do that, the detailsview doesn't update the record.

Forms Data Controls :: Update DetailsView Data By Updating Object?
Mar 23, 2010I'm using a DetailsView object to present a record from a database in table format. I'm actually using and ObjectSource object as the data source for the details view. In the object I am using as the source for the ObjectSource, I have paired properties that hold decimals. This is, I have a property called Year1 and another property called Year1Change. This for years 1 to six. The values from the Year1 properties are in a cell, whereas the change values are bound to texboxes. The code for the frontend is the following:
[Code]....
Now, as you can see in the tbYr2RtCh textbox, I have an OnTextChanged property to call an event handler. This is because I want to do two things when the text changes. The first one is to make the font in the textbox bold if the value it holds is different from the Year2 property. The second one is to change the text on tbYr2RevCh to adjust the revenue for the percentage increase in the rate. The problem I have is that I cannot access the object that is the source for the data and make those changes directly in the object, instead of having to update the database. I don't want to update the database until the client says so, but the changes should be calculated immediately. I thought about creating an method in the object that I could specify in the ObjectDataSource as the update method, but I'm still not sure how to go about it.

Aug 12, 2010Here is the scenerio:I have a radtabstrip (with 2 tabs) at the top of my page followed by radMultiPage control Tab 1 displays pageview 1 which has a gridview showing data from our database and allows for selection or deletion of data tab 2 displays a detailsview when gridview_selectedindexchanged(from tab 1) is fired.Problem... If you select an entry in the gridview it switech the page and the detailsview into editmode (works fine) but if you then click on tab 1 without clicking update or cancel in the detailsview, the data is updated. This is what i don't want as the user has basically abandoned the changes.So what i need is a what to say ... if the detailsview is in edit or insert when the tabstrip is clicked then cancel the insert or update. I tried switching it back to readonly mode but that did not seem to work.
View 2 RepliesForms Data Controls :: All Row In MS Access Table Are Updating With Detailsview Edit?
Nov 22, 2010I have used this before with no issues. Now I get to the page with the detailsview using parms I pass with the key to the row. When the page opens the row I want to update is displayed.
I am having 2 issues. One when I change any of the fields and hit Update (the Edit button),
all rows are updating not just the row displayed. The second problem is I have an update_date and an Updated_by field with code in code behind in the Onitemupdating event and they are not updating at all. (This bit of code works fine in another page I have to updated similar fields on an insert).
Forms Data Controls :: Updating Two Detailsview Controls With Paging?
Mar 11, 2010have two detailsview controls on the same page, one showing pictures, one showing the comment on the current picture. I separated them because they are in different parts of the page (just in case someone was wondering why). They both bind on the same objectdatasource. The issue is that since I use paging to navigate the pictures and i dont know how to also update the comment detailsview control to the same page as the picture.
View 3 RepliesForms Data Controls :: DetailsView BoundFields Auto Binding Not Updating Business Object On Update
Feb 18, 2010I have a DetailsView (DV) control, an ObjectDataSource (ODS) control, and a button on a page. I have 2 classes in the App_Code directory (Customer and CustomerDAO). The DAO class provides static methods for the ODS control and simply hack values in (ie...no real database selects/updates). The Customer class has 2 properties (Id and Name) and a default constructor. The page takes an ID on the querystring and determines if the DV control is in insert or edit mode. If in edit mode, it sets the SelectParameter on the ODS (id field), calls ODS.Select(), and then calls DV.DataBind(). The existing (although fake) customer is loaded and display properly when this happens. I then change the name of the Customer in the DV and click the Button to save the new data.
Everything seems to be wired up correctly as the UpdateMethod that is specified in the ODS control is called and succeeds (even in my real example with my database). The problem is that the BoundFields in the DV control have not been updated with the new values and therefore the existing values are updated in the database and my changes are lost. I have handled the OnUpdating event of the ODS and the values are still the old values. I have also handled the OnItemUpdating event of the DV control and the NewValues IOrderedDictionary still has the old values in it also. In looking at the MSDN article for the UpdateMethod, it states the following:
Parameter Merging
Parameters are added to the UpdateParameters collection from three sources:
From the data-bound control, at run time.
From the UpdateParameters element, declaratively.
From the Updating event handler, programmatically.
I am using the BoundField classes in my DV control so I would have assumed that the first bullet above would have handled the updating of values, but it doesn't appear to work with the way I am doing it. If I set the values explicitly in the OnUpdating event that is fired by the ODS control (the 3rd bullet) the right values are updated (again...even in my real database situation). It seems like my only issue is that the automatic binding that I expect from the DV control isn't working as I would expect it to. Here is the code that I have in my fake example:

Forms Data Controls :: Gridview And Detailsview - To Click Two Times On The Select Button To View The Detailsview?
Nov 17, 2010 I´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.

Forms Data Controls :: Duplicate Rows Of Data In GridView - Stop This?
Jul 29, 2010I'm getting duplicated rows of data showing up in my GridViews. I have two GridViews, each showing different data. I'm using SQL queries to retrieve the data from 2 database tables (1 query pulls from one table and the other query pulls from a second table, but references the first table in the WHERE clause). The GridViews were not duplicating data until after I added the Data Binding code to each GridView event handler and the button click event handler (outside of the GridView). I double checked my SQL queries by running them in TOAD and did not get any duplicated rows. So the issue is not with the SQL queries. It appears to be the GridViews causing it, or the Data Binding, or combination of those two, but I'm not sure what it is.Has anyone heard of or seen this? If needed, I can post my VB code and GridView code.
View 7 RepliesForms Data Controls :: Delete One Duplicate Record Of Many Duplicate Records
Mar 15, 2010I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate records?

Forms Data Controls :: DetailsView Accessing Textbox Through Code Behind?
Jan 25, 2010I've been playing with a certain detailsview for most of last week. This particular control is located within a panel that is hidden until a user clicks a linkbutton on a gridview. Then the panel's visible property is set to true and the detailsview is populated based on the commandargument passed through the link button. What I've discovered is that with each postback, the datakey or control parameter, still not sure which or if both, is lost. I've discovered a lot about ViewState and how controls work and am a bit surprised that something as common as using a detailsview within a gridview wouldn't be handled better than it is now. I have been able to get the proper information to build a correct select statement when the user decides to edit a record. I am now working on an update statement, but for some reason while I have the right key to update the right record, I am unable to access the user-generated data that was entered in the details view.
For instance, I select record with ID of 1 in the gridview. It pulls up the detailsview and I can view it. I then click edit. The correct record is still there. (It was previously going to default). When I enter new text in a textbox and click update, the app still knows I am working with record #1 but doesn't seem to be able to find the textbox control. I have currently hard-coded a value into the field just to see if I could actually get the record to update and it did. I am using an OnInit to cause the sub to run and think this might be the problem. However, I have been unable to find a better way around this.
Here is the sub that executes on the OnInit() of the detailsview:
Protected Sub notes_binding()
If notesDetail.CurrentMode = DetailsViewMode.Edit Then
sqlNotesUpdate.UpdateCommand = "UPDATE [Oilchange_Notes] SET [notes] = '" & CType(notesDetail.FindControl("notes"), Textbox).Text & "' WHERE [vehicle_id] = " & Session("unitNumVal")
sqlNotesUpdate.UpdateCommandType = SqlDataSourceCommandType.Text
sqlNotesUpdate.Update()
End If
sqlNotesUpdate.SelectCommand = "SELECT * FROM [Oilchange_Notes] WHERE ([vehicle_id] = " & Session("unitNumVal") & ")"
End Sub
And this is the error I get: Object reference not set to an instance of an object. If I'm correct about why it's not pulling the actual value or even acknowledging the control exists and is actually 'notes' (it is), then at would point would be the best to place this code?

Forms Data Controls :: DetailsView - Set Textbox Text When Going To Insert Mode?
Jan 19, 2011I guess I'm not sure exactly how or where to do what I need.
First off - here's what I need - - when the user clicks on the NEW button in the detailsView, I have the User.Identity.name captured in a variable and I need to set one of the textboxes (InsertItemTemplate) named 'txtNew' to that name.
I've tried using the ModeChanging (and ModeChanged) event:
Dim
dv As
TextBox =
CType(DetailsView1.FindControl("txtNew"),
TextBox)
If (e.NewMode =
DetailsViewMode.Insert)
Then ....
However, no matter what, 'dv' always shows as 'Nothing', so I can't change the text of it.
Where do I put the logic and what am I missing?
Forms Data Controls :: DetailsView - Binding Datafield To TextBox On Update?
Jun 29, 2010I have a bound field in a DetailsView that I want updated with the contents of TextBox2.Text when I update. I have TextBox2 set AutoPostBack True. Cannot remember how to move the contents on update. I tried converting the "Description_Update" to a template field without success.
I can copy and paste the contents of TextBox2 into the DetailsView and it does update as do the other DataFields.
<asp:TextBox
ID="TextBox2"
runat="server"
Height="80px"
TextMode="MultiLine" Width="360px"
Font-Size="Small"
MaxLength="120"
Text=""
Font-Names="Calibri" AutoPostBack="True"></asp:TextBox>
<asp:BoundField
DataField="Description_Update"
HeaderText="Descrip"
SortExpression="Description_Update"
/>
Do I need to use adn Eval or DataBind function or both. I have triued several combinations and do nothing but continue to butcher the database tables.
