Forms Data Controls :: Detailsview In UpdatePanel Sends NULLS To Db On Update?
Mar 4, 2011
I have been struggling with an issue with the Detailsview that I'm using only sending null values to my sqldatasource update. I have seen people on the forums with this problem before but none with my specifics. Essentially, I'm creating a master/details scenario but using ajax updatepanels. A Gridview holds the master records and upon selection of that record the Detailsview is populated and brought up in a modal box. This works fine to display the data in the Detailsview. But upon update all nulls are sent back. I've evaluated the NewValues collection in the Detailsview OnItemUpdating event, and see all nulls. I read a posthere that talks about the KB article KB941155; which states a problem with .NET not being able to find a bound control in template situations:http://support.microsoft.com/kb/941155I wasn't sure if this applied to me since I am using Master pages. A couple of other notes. I am using BoundFields in my Detailsview, as well as a sqldatasource with a stored procedure updatecommandtype. The DataKeyNames are being set correctly as well.

I'm looking to find some command or control that will change fields in a detailsview insert a 0 if there was no data inserted into them. Some example code from my boundfield is:
<asp:BoundField DataField="Assignment_Travel_Time"

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 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 :

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:

I'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.
I get a message like this if I change the "State" field to blank when doing an update
The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.

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");

I currently have a page that is used to insert or update records in a DetailsView using an EntityDataSource control. Insert is working perfectly. However, Updating is not. I have the default view set to insert. In PageLoad, I have:
[Code]....
However, the DetailsView always defaults to the first record in the table rather than the record with ID that is equal to the ID querystring parameter. I am not sure how to make it select the correct record. From spending a while researching, it looks like I might need to use a QueryExtender control on the Entity DataSource, but haven't been able to figure out how to configure the QueryExtender correctly.
There is also perhaps some sort of datasource="stuff", databind() that I could toss in there but again.. not really sure how to proceed.

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.
