I changed a text field to a template field assigning the selected text and the selected value is being assigned to another currency field also templated. I get aa error
[FormatException: Input string was not in a correct format.]
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 created a site that updates a database through a detailsview grid, however it wont let me input decimals. An example of my code is
HeaderText="Assignment_Job_Type" SortExpression="Assignment_Job_Type" />
I have a SQL DB with just 2 fields, ID and TEXT.What i was trying to do, was placing a Detailsview in EDIT MODE, then selecting from the DB like SELEC TOP 1 Text FROM DB.Then i placed a Ajax HTML Editor in the template field.How can i, keep the HTML Editor on the page, and use it for INSERT and/OR EDITING ?e.g.: on the first time the user opens the site management page, it will be blank, so it will show the HTML with no text on it. but the bottom button will be UPDATE and CANCEL. So when he enters the TEXT he clicks on UPDATE.

On my DetailsView for inserting, I have a field "manager code". When the user types in the code, I want another field "manager name" to be populated based on a lookup table in the database. I have done this on a FormView using code behind and "ontextchanged". How can I do this in DetailsView?
View 3 RepliesI have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".
I have a table named RECIPE which is linked to an other table name RECIPE_STATUS
In RECIPE table I have a field named Status_Id which contains the name of the Status which is fetch from the RECIPE_STATUS table based on this ID.
The RECIPE table sample information are as follow :
ID Name Status_Id
====================
1 Test1 0
2 Test2 1
3 Test3 2
The RECIPE_STATUS entries are as follow:
ID Name
========
0 Locked
1 Running
2 Free
From an ASP.net page I would like that my user is capable of changing the RECIPE_STATUS from a given recipe. For that I have a DataGrid which is bind to the RECIPE table.
But then what I would like is that the STATUS shown to my user to be the name Locked,Running or free depedning on the Id
How can I bound in my Datagrid the Recipe.Status to be bind to RECIPE_STATUS.Id ?
IN addition to that, If my user change the status for a given recipe, it should be properly save.

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.
View 3 RepliesHere 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 RepliesI 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'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.
View 3 RepliesI want to integrate paypal inside my shopping cart. For that it requires a html form to be embeded inside .aspx page with the action to paypal and method is post.

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 REALLY new to ASP.NET MVC, and it is alien to my way of thinking.In my project, I have managed to get as far as allowing the user to add, edit or delete entries from a table. What I want to do is ensure that a specific field (i.e. "Tank_Number") does not get duplicated. What is the correct way to implement this?
I would like to use custom validation in the model class, the reason being the handy error messages, but am getting more confused as I read more articles. At the moment, I am using an If statement in the Controller, but it isn't ideal.
Here is my example code:

I've got a Gridview which has a datasource to a particular database.
I've got a DetailsView which has a datasource to a table in another database.
when I select a Gridview row, I need to populate a field in the DetailsView with the Primary Key field (showing in the Gridview) from the Gridview.
Can this be done (if so, how?)?
Also (but not as important) :
If there's no field related in the second table, I'd like it to come up in Insert Mode - if there is a field related, I need it to come up in Edit mode

I can't find a method to fire a handler
