I have this problem everytime I change the select command to a custom command, and I do not know what is causing it.
My Formview will not update when i hit the update button, page refreshes but I get the same info, not the updated info. I set up my DataSource to CRUD only one table, then change the select statement just for the ItemTemplate of the Formview, leaving the rest, but it will not update
I am making a message module in asp.net with database of sql. i have made a gridview and enabled selecting. and a form view is synchorised with grid view on selecting. i am writing update sql but could not get a way to take data on Gridview or Formview to compare the record in sql database.
this is my page view
[Code]....
This my vb code
I have a web page with a gridview & formview (master/detail relationship) combo. On page load the gridview shows all records from a SQL table. On my page I have a button that when clicked shows the formview in Insert mode to allow users to add a new record to the data. I have also added a column to my gridview that has a link. When a user clicks this link it hides the gridview and shows the formview in edit mode with the detail from the record selected from the gridview.
In my formview I am using a listbox control to allow users to select multiple values. The choices in the listbox are populated by a SQL data table. I have successfully written code to post the selected listbox values to my SQL data field during Insert. When the user selects a record to edit I have code in the databound event to select values in the listbox from the choices based on the value in the sql data field. This works as well. My problem is that I cannot figure out the correct code to update my SqL data when a user is editing the record and makes changes to the selected listbox value. I have included my design code for my listbox in my formview edittemplate and also my behind code that I have attempted.
<td
style="width: 454px">
<asp:ListBox
ID="lbox_ConstructionType"
runat="server"
DataSourceID="SqlDataConstructionTypes"
DataTextField="Construction_Type"
DataValueField="Construction_Type"
SelectionMode="Multiple"
Width="144px"></asp:ListBox>
<asp:TextBox
ID="tbox_Ctype"
runat="server"
Text='<%# Bind("ConstructionTypeID") %>'></asp:TextBox></td>

I've posted this some place else but have not heard from anyone and hoping I get better luck here.

I am using a stored procedure for a sqldatasource to update a formview. I believe that I am passing the Obligation_Status value correctly to the stored procedure but the oblgation status field is always updated AS NULL in the database. Does anyone know what I am doing wrong?

One of the fields on my formview is a dropdownlist. When I go into edit mode the dropdownlist gets set to the correct value and works fine up to this point. Problem is I just can't see how to get the newly selected value of the dropdownlist to persist to the database when update is clicked. The DDL is a category list and I want to allow changing of the category for each record. Like I said I have it working so it displays the correct category for the record but if I change the DDL (change category) the new selected value doesn't get updated in the database. It just keeps using the binded value that was originally assigned to the selected value of the DDL. see code snippit
[Code]....
The above snippet is how I am binding the DDL. Now to not bore you with a ton of code paste I use various events of the formview to make sure the value displayed in the DDL is correct for the record that I am viewing at the time. All that works just fine. Where I need some pointers is the when I enter edit mode and change the DDL from say fire to ice it isn't getting persited to the database, all other info in the record gets updated just fine but the DDL never changes. I have tried several angles to getting this working and TBH my brain is yelling BREAK TIME.
why my formView control is not updating?

I have a 4 formviews present on a page. Three are updating to the DB without issue when the update link button is clicked. One is not. I have the DataKeyName set and still it doesn't save.

I want to bind an object to a form view.
[Code]....
Now, is it possible to generate a new object on update, without getting and reading each textbox with findcontrol?
I have a strange issue with the FormView. After working through some issues getting the update to work (as this is my first experience with FormViews) I now have a new issue. After I perform an update, and the FormView updates and returns to read mode, if I hit F5 (refresh) the FormView performs another update to the datasource, despite the fact it is read-only mode and none of the fields on the screen are editable.
I would think that a refresh in read mode for the FormView after an edit would simply refresh the data from the database, not perform another update. Again, the FormView is in Read Only Mode, but a refresh is creating another Update event (which I can debug and see if I break in the ItemUpdating event). This only happens after I perform an edit, not when the page initially loads.
I have an access database where when the record is updated I would like to automatically check a box and update the date to the current date in an Access 2002-2003 database. I've tried this for several days without any resolution and can't find anything that works on the net. ...I'm new at this.
I'm using VWD 2005 Express and Expressions Web 3.
Here is a short version of the code.

I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
I have a nested formview. I need to set a value for a textbox when I'm in insert mode from parent formview which is editmode.
View 4 RepliesI have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?
View 2 RepliesUsing a class component, an Object data source and a formview I am successfully pulliing data from a SQL database. In some cases the rows contain one or more Null values and I would like them to be ignored completely. My simple code follows:-

Rose Cottage, 123 New Road, Margate,
I am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?
I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.
I have an asp.net page with a gridview control on it but I want to allow the user to also be able to update the selected row from a series of textboxes. I simply need the code for a button click event to do this.
button is called button1
textbox is called textbox1
gridview control is named gridview1
record to be modified is in 3rd column called PlayerName
The row to be edited will always be the only record shown and will always be selected by code I've already written. I will also need to know if the record must be set to edit mode to make the button click code work.
I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.
View 1 RepliesDuplicate Data in Gridview and Updating textbox in DetailsView
View 2 RepliesI have a gridview based on a sqldatasource that has some colums from which two colums showing the data of two fields: field1 and field2. field1 is an ID which should not be updated and therefore it is readonly=true. The sql-query from the sqldatasource is:
SelectCommand="SELECT field1, field2 from anyView"
What I want is, that when a row is updated, then the value from field1 should be copied to field2 The update-query is:
UpdateCommand="UPDATE myTable SET field2=@field2 WHERE field1=@field1"
My idea was, that the @field2 paramter gets the value from the query string out of field1:
<UpdateParameters>
<asp:QueryStringParameter Name="field2" QueryStringField="field1" Type="Int32" />
</UpdateParameters>
But this does not work. Is there an easy way to copy the data from field1 to field2 when updating the row? In addition, is this possible, even if field2 ist not shown in the gridview (i.e. field2 is selected in the query but is not a field in the gridview but should be updated with value of field1).
I have a requirement something as below.
1. I will click on the EDIT link in one of the grid view row. The row will change to edit mode
2. I will update the values and click update link in edit mode and edit mode closes.
3. At this point I need to capture the datakey of the updated row into some variable

for the updating and deleting binery data in Gridview same like that i want to updating and deleting data in detailsview?
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.
I'm using ADO.Net code to access and update the data from the database. I'm using GridView for presentation. I wish to preserve old values of all the columns while updaing the records.
I'm using Code behind and not d Data Source controls. I wish to list the old records once record is updated.
