Forms Data Controls :: How To Access The Data In A DetailsView
Jun 25, 2010
How does one access (programatically) the data in a field in a DetailsView? The DetailsView in question has just one record but 10 fields. I assumed (wrongly?) that the DetailsView has one row, representing the record, and 10 cells, representing the fields? How does one access the fields by name?
I've tried
MyText = Dataview.Rows(0).Cells(5).Text
but I'm told that cells(5) is outside range (the field I am trying to access is the fifth field).
I use ObjectDataSource and DetailsView for Updating records . my Bll input parameter method is an Object instead of regular parameter . So i though i could make my own ObjectParameter in ItemUpdating event of DetailsView and i need some modifiation on the data that user input on boudfield in detailsView . I don't know how to access BoundFiled data from ItemUpdating Method of DetailsView.
The Detailsview has a template containing a textbox for one of it's fields.When an item is selected in the Gridview, I want to set a property of the textbox. How do I do that? I've tried Findcontrol for the item during Prerender of the detailsview. I've also tried many other things. Below is a portion of my aspx code followed by my VB code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="LU_DutyStations_ID" DataSourceID="SqlDataSource1"> <Columns> asp:CommandField ShowSelectButton="True" /> <asp:BoundField DataField="Duty Station Code" HeaderText="Duty Station Code" [code]...
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 have a detailsview control, which I use to enter data and save to the database. I am using object datasource to connect to the db. The detailsview control has autogenerateinsert = "true". When the insert is successfull, I want to set some variables and and to redirect the page to a different one. I don't know how to access the insert button click event of the detailsview to do it. If there is different solution like using <insertItemTemplate> and using custom linkbuttons.
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 a detailsview control which I use to enter data and save to the database. The control is connected to the db through a objectdatasource. When the insert is successful, I want to set some variables and redirect the page to a different one. The detailsview control has AutoGenerateInsertButton="True". I don't know how to access the insert button click event in the code behind,
I am trying to use a DetailsView to enter a new row into my database, but need to enter a further row in a linked table at the same time.
I am able to use the "iteminserted" event to gain control after the event has completed, but I need the key to the row i just inserted into the main table.
I am using a dataset, so the insert is managed by a tableadapter which has been configured to return an integer with the newly created identity of the row i just inserted.
Does anyone know how I can get access to that identity? is it in the "e" object of iteminserted? how do i find that if it is?
Here is the VB CodeBehind I am using to insert the row in the linked table (the DetailsView has just inserted a row into the "Books" table and the database has just assigned it an identity which should have been returned to somewhere by the tableadapter. I need that identity as a key to the "BookAuthors" table):

This is the ASP code for the DetailsView and the DataSource:

And here is the code for the tableadapter i am using
I am trying to arrange the information from a SQL record into a 3 column by 3 row table to fit the form presentation that I want. I have placed on the page 3X3 table and then tried to place a detailsview in the first cell for the first picture called P1dv.
I have place a detailsview in the last cell that would control the paging of information called Controldv. I need to fiqure out how to link P1dv paging to Controldv page action. I am using visual web dev. 2005. I am not updating or editing these are read only views.
example of what i need the form output to look like:
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 gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
I have built a set of custom business objects that I have successfully bound to the GridView and DetailsView controls using the ObjectDataSource. I have been able to provide insert/update/delete functionality and all is working as expected. However, I am trying to wrap this functionality into a custom user control that allows the consumer to specify a table name and a list of column names and have it build this functionality on the fly without regard to the table structure (ie...available columns). I have been able to successfully get the GridView and DetailView to build the columns from code behind and I had all the CRUD working while using 2 panels to show/hide the GridView and DetailsView controls, but I wanted to add some AJAX ability to the control using Matt Berseth's modal popup example to make the interface slicker. The problem I am having is that the EditItemTemplate for the DetailsView control has to be specified in the code behind (because of the flexibile nature of the columns) and I can't figure out how to bind the data from code (rather than having the columns defined and bound in the markup). For all intensive purposes, I am trying to find the code behind counterpart to the following code snippet that binds the data to the textbox:
I have a database containing a table with about 700,000 images so I recently enabled Filestream. However, I can't figure out how to render the images.
I have an Imagefield control within a Detailsview which is using an .aspx file to render the image through the DataImageUrlFormatString (which is typical). In my select statements I tried changing the binary field containing the image from objectdata to objectdata.PathName() per the Microsoft documentation but this does not work. I get the red X image box.
Just want to know if it is possible to Dynamically Populating a DetailsView with OleDb Data Adapter ? It has to be done on the Page_load because it has to display a users details that i must be able to edit!
I use a Detailsview, Entity Data Source to edit/update my table with only 3 columns.(it has primary keys).
Everything works fine inserts/edit in dev environment. but when i run this in release mode. i cannot update existing data in the database with the detailsview. whenever i update and save page gets refreshed, but nothing gets updated. but whenever i insert a new record, and then i try editing it. it works.?
Note: i handle DetailsviewItemUpdating,DetailsviewItemInserting events to do some custom checks.
I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.
The scenario:
DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.
Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.
when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.
The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.
My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".
I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.
code:
The SqlDataSource used to select the parameters from the table and populate the DetailsView

I am using DetailsView box (Visual Studio 2010) to display employee data based on Access table. One of the fields is an employee email, designed in the table as HyperLink. I want this field to be displayed in DetailsView as HyperLink also.
i want to insert data from details view to database.i took a detailsview control and some textboxes, and one button. then how can i save the data to database.my code is below.
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?
