Forms Data Controls :: Setting Values Before An Update In Detailsview Not Working?
Nov 23, 2010
Background: I open a page that has a detailsview control using Accessdatasource. It is automatically opened with the row I want to update as I get there by passing the key as a URL parm. The update works for all fields except 2 template fields I added. I added a field for update date and updated by which I want the code to populate in the code behind so the user does not enter it. I have the same login on another page using an insert and it works fine. I cannot figure out what is wrong on the update and I tried everything. The code behind is in the OnItemUPdating event. code behind:
protected void set_update_date(Object sender, EventArgs e)
{
TextBox tbdate = (TextBox)DetailsView1.FindControl("TextBox_update");
[code]...

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If
But this returns an error of "Object reference not set to an instance of an object." how to accomplish this - either using the method above or another method? The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"

I am trying to programmatically set some lables inside a DetailsView that is populated by an ObjectDataSource. The detailsview is handled in an unusual way with one TemplateField that has one ItemTemplate that has one table that has two rows of significance and a boatload of bound items. I'll be working on the EditTemplate next. But now I need to set the top row lable values programmatically baised on the type of data that comes-up. I have scoured the Internet looking for ideas and found two possible approaches - neither worked. I get the error about something not being set to an instance of the object - or something like that.
Here is the ObjectDataSource:

Here is the DetailsView:

My first approach was to set the OnSelected property to the following code in the code behind, which executes:

My second approach was to delete that OnSelected property and try the following code in the code behind:

I am using DetailsView to pull database records and want to set the word wrap on the Edit page. But when I enter Edit the data shows up as a single long text string, (see pics). In the default display the text wraps fine. I have played with every option that is available even trying to set the field to a TemplateField but nothing I do displays the Edit test wrapped.
This is the edit page, notice that the Info field text is just a straight line.

I have two detailsview, detailsview1 and detailsview2. Both are for pagination purpose.
Both are using same ObjectDataSource control (DataKeyName and DataSourceID is same in both ObjectDataSource control)
OnDataBound Event both called same Event RefreshDetailsView and In case of page index changing both used same method.
But when I do pagination using my detailsview2, this does not work only count got changed.
While detailsView1 works fine in case of pagination

I have an update button in a detailsview. based on certain criteria in the data that is being updated (blank field), I want to stop the update from happening. I tried putting the following code in my UpdateButton: 'check to see if the status is 'complete'
Dim statuscheckbox
As CheckBox =
TryCast(formulationDetailsView.FindControl("FormulationCompleteCheckBox"),
CheckBox)If statuscheckbox.Checked
Then
'check to see if color code has been entered
Dim colorcodetextbox
As TextBox =
TryCast(formulationDetailsView.FindControl("ColorCdTextBox"),
TextBox)If colorcodetextbox.Text =
""
Then
'show a message, the color code has not been entered
MessageBox2.Text = "Please enter Color Code prior to complete"
statuscheckbox.Checked = False
resetformwithoutediting()
End
how to stop this code from proceeding to the update?

I've got a DetailsView control with Edit and Update enabled. I'd like to write the edited record to an XML file after Editing. What's the best way to do this? I thought I could write to a text file and concatenate the db fields between XML tags but is there an "automatic" or best practice way to do it?

I'm inserting data into a SQL database through a detailsview. When a user inserts an incorrect data type or leaves a required field blank it shoots off to a big error screen. Is there a control that I can use that will allow it to give an error (with a little star or something) that says which field is incorrect without the big error screen?

The DetailsView control has in its
Events an
ItemCommand event that uses the
DetailsViewCommandEventArgs event arg class which has a
CommandName property.
My questions are...
What are the possible values (e.g. "Select", "Insert", etc.) for this CommandName property when operating a standard, uncustomized DetailsView control?
Which order do the following fire in?
ItemCommand
ItemCreated
ItemDeleted
ItemDeleting
ItemInserted
ItemInserting
ItemUpdated
ItemUpdating
The "ing" events are currently being intercepted so that if the user doesn't have permission I set the e.Cancel = true and the "ed" events have redirects to send the user back to a list page that shows the items they just added/updated/deleted. However, I am not able to capture the Cancel button on the DetailsView control since there's no event for it. What I want is to redirect the user back to the list page if they click on Cancel as well.

I have a asp:DetailsView control with the first column are the field headers and the second column is the record details for a given user.
The DetailsView is bound from 4 tables, I need to be able to edit/amend any field. Is there another way I can achieve this from the DetailsView? Would I need to create templates for each table entry then Update SET on each template, would that do it?

I want to update a record in a detailsview which contains a decimal value which I would like the field to formatted as currency while editing.
When I try to update the record I get an error about trying to pass a formatted value to an unformatted table column. The ApplyFormatInEditMode is set to true and you are cautioned by intellisense about unformatting befor updating the record. This is databound field.
Is this a simple as x = Val(detailsviewrow(1).tostring) ?
Here the code I am trying :

Im not sure what i could have done wrong here but i created a dataset (ran a query and it returns the correct data) - created my BLL class - bound the ObjectDataSource to the control using the BLL - ran the site and all the data is showing as expected. Now i click edit columns (from DetailsView smart tag) and the selected fields are empty. I refresh the schema and this makes no difference. What could i be doing wrong?

I'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection.
I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?

I have a Hyperlink control in an ItemTemplate inside of a DetailsView. The DetailsView is inside a view of a MultiView which is inside of an update panel.
I am using binding syntax to bind the NavigateUrl property of the Hyperlink. However, the text shows up but when the mouse point moves over the hyperlink, the pointer doesn't change to a pointer hand like it should. And, nothing happens when the HyperLink is clicked. Here's the syntax I'm using:
<ItemTemplate>
<asp:HyperLink ID="hlWODWorkSpace" runat="server" ToolTip='<%# Eval("WorkSpace") %>'
NavigateUrl='<% Eval("WorkSpace") %>' Text='<%# Eval("Workspace") %>'
Target="_work">
</asp:HyperLink>
</ItemTemplate>

I 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.

I am using a gridview to select a record and control that record using a details view. I am using a class based objectdatasource to link the data for select, update and delete. Sofar the select works but the update fails. Here is my error message:
ObjectDataSource 'odsDetailsView_1' could not find a non-generic method 'UpdateSet' that has parameters: setId, TYPE, iHPlayer, iAPlayer, iHRuns, iARuns, iH8Break, iA8Break, iHe8s8, iAe8s8, iH15BRn, iA15BRn, iHWins, iAWins, SET_ID, MATCH_FK, HOME_MEMBER_ID_FK, AWAY_MEMBER_ID_FK, HOME_TABLERUN, AWAY_TABLERUN, HOME_8BALLBREAK, AWAY_8BALLBREAK, HOME_E8S8, AWAY_E8S8, HOME_15BRN, AWAY_15BRN, HOME_TOTALWON, AWAY_TOTALWON, HOME_POINTS, AWAY_POINTS, LOCKED, GROUP_FK.
The first group of parameters have lower case letters and they come from my objectdatasources update method parameters. The second group of parameters are all capitalized and they are the fields in my SQL database table (and I don't know how they wound up in the error). This might be a clue.When executing the code my class method never gets the chance to execute because the error pops up before the code gets there.
Here is my objectdatasource:
