Forms Data Controls :: Detailsview Dropdown Updating?
Jan 3, 2010
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.

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.

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 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 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 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 have a gridview that has a dropdown on a template on the row. The user is wanting to change the value and update the record automatically. I know that when the value changes, I need to have the OnChange to trigger. I am not sure how to get the row so I can get the record ID so I can create a SQL statement to update this field.
Should I be using something other than the gridview?

I am using a DetailsView Control and have a "MemberStatus" field.
When using the templates in edit mode, I am using a dropdownlist to change the member status.
e.g.
<asp:TemplateField HeaderText="Member status:" InsertVisible="False" SortExpression="MemberStatus">
<EditItemTemplate>
<asp:DropDownList ID="ddlMemberStatus" runat="server" DataSourceID="adsMemberStatus" CssClass="eitField" DataTextField="MemberStatus"
DataValueField="MemberStatusID" Width="120px" SelectedValue='<%# Bind("MemberStatusID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label6" runat="server" Text='<%# Bind("MemberStatus") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
What I would like to achieve is, if the MemberStatus is changed during edit mode, e.g. from "Active" to "Deceased"
I would like to enable certain fields e.g. txtBoxDateDeceased, and attach a RequiredFieldValidator for the textbox field.

I have a datasource:
[Code]....
I have a detailsView bounded by some other datasource. There is a dropdown in detailsview which is bounded by sqldatasource named "sdsNature" . Here is the templatefield for dropdown:
[Code]....
I want to show FNature instead of FNatureID in the selected mode as Label and in Edit mode as dropdown. When I am running this project, in Select mode it is showing FNatureID instead of FNature and if I click to Edit the record it is displaying following error:
'lstNature' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value Do I have to give some If else condition that if FNatureID is .... then dropdown should display FNature.... If yes then what should be the code?

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 fields for a contact. 3 of those fields are drop downs to values from another table in the database. For example, Contacts has the foreign key for departmentid which pulls from the department table to get the description. But when i click the Edit and update, this does not update my database. It acts like nothing happened.
EDIT: Just noticed this, but when i change the name and click update. I get an error telling me that EmployerCode cannot be set to null. I know that the database is set to not nullable. But i do not understand why the original value is not being pulled. When i load the contact, all three of the drop downs have values from the database loaded. Although i am seeing that all three are displaying the first item in the table and not the item the contact has in it's values. But when editing the contact, it acts like those values are not loaded and are just null.
