Forms Data Controls :: Detailsview Not Updating If Gridview Not Visible?
Dec 14, 2010
I 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.

I have one GridView called GV_IssTypeDesc and one DetailsView called DV_IssueLog.
The scenario is that i only want GV_IssTypeDesc gridview to appear when DetailsView DV_IssueLog is in edit mode. How do i accomplish this?
I refered to: [URL]
For now i have done the following:
UpdateIssue.aspx
<asp:DetailsView ID="DV_IssueLog" runat="server" Height="50px" Width="400px"
AutoGenerateRows="False" DataKeyNames="dbIssID" OnModeChanging="DV_IssueLog_ModeChanging"
DataSourceID="SqlDS_IssueLog" BackColor="White" BorderColor="#E7E7FF"
BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal">
<asp:GridView ID="GV_IssTypeDesc" runat="server" AutoGenerateColumns="False"
CellPadding="4" DataSourceID="SqlDS_IssTypeDesc" ForeColor="#333333"
GridLines="None" Visible="false">
UpdateIssue.aspx.vb
Protected Sub DV_IssueLog_ModeChanging(ByVal sender As Object, ByVal e As System.EventArgs)
If e.NewMode = DetailsViewMode.Edit Then
GV_IssTypeDesc.Visible = True
Else
GV_IssTypeDesc.Visible = False
End If
End Sub
The "e.NewMode" is underlined blue in color and it is stated "NewMode is not a member of System.EvntArgs".
How do i solve this problem?
By the way, I am using Web Developer 2008, VB.net.

I know the back button always presents a problem, but this one doesn't make any sense.
I have a simple details view and a button on a page. The button sends the user to the homepage. I am trying to prevent the user from being able to use the detailsview if they click Back in their browser.
This is the button click event
[code]....
When the button is clicked...oddly the user is sent to the homepage then when they click the browser back button they are sent to previous page with the detailsview still visiible.
I know I am missing something, can someone fill me in?
Why is the detailsview still visible?

I have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.

I have a detailsview control linked to a SQL DB. I have created a template field with various controls within. When I click on edit and change the values and press update. The detailsview control changes back to read only and displays the original values. I have attached the code for the control and datasource below.

I am having issues with this.. If you could help that would be great. I am not a coding expert, but I am trying to learn as I go. I am having problems taking the value from my dropdown list (tabl1) and updating table2 with the selected value.I have my grid / form showing my table2 data, I have 1 of the dropdown fields being populated from table1, when I change the specified dropdown box and click update, the data in table2 stays the same.

Here 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.

I 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).

I'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.

have 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.

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.

I 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:

I am basically trying to check the contents of a field in a data base (Course) to determine if a button (btnMisfills) shoulf be displayed for a specific user. I am sure ther are probably better way of doing this, and any suggestions would be appreciated. However I am using the few tools I know how. Everything works as expected as long as the DetailsView is visible, but I have no need to display the detailsView. When I change the detailsView to visible = false, my logic does not work. Apparently visible = false means the detailsview is not created. If this is true, how else can I check for the contents of the course field?s there a way to check a field in the sqldatasource?

What to do to show DetailsView even when there is no data in underlying datasource?The problem is that when DetailsView is not visible, the command buttons are also not visible. So I can not insert a new record to a database. I would like to have always visible DetailsView with its DefaultMode set to ReadOnly.If it is not possible I would like to ask for an workaround for this problem.
One workaround which I have on my mind is to check if datasource have any records. If no then programmaticaly change DefaultMode to Insert. However this causes another problem - how to count the number of records in DataSource.All my problems are related to the ASP 3.5
