I have a problem specific to the gridview control, i am using the datasource to generate an update method for the data in my table.
Some of my columns are display only fields so i have set them to "read only = true" Everything seems fine when the page loads but when i click update, the columns that were editable update fine but the ones set to read only have now updated the databasewith a null value. Am i missing something here?

How to update a colums value of a Row in a gridview on Row Command Event Handler. I am using a SQL Datasource.
[Code]....
I have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).
I have an UpdateCommand as follows
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:NHLPOOL %>"
SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"
UpdateCommand="UPDATE PlayerStats SET Goals =@GOALS, Assists =@ASSISTS, AsofDate=GETDATE() WHERE PLAYERID = @PLAYERID">
</asp:SqlDataSource>
The issue is I want the PLAYERID GV column to be READONLY but I get a runtime error when updating if the PLAYERID is READONLY.
I get the error "
Must declare the scalar variable "@PLAYERID"."
I need to change ReadOnly from false to true for one column in GridView depending on who the user is. In my particular case it is a BoundField (also I would like to know how to do it for a Template field as well) and DataField is "dteRequired". I would like to code something like that right in the Page_Load handler:

there are 2 pages (SummaryGridviewPage.aspx and FormviewPage.aspx) there are insert, item and update templates in the FormviewPage 1st case - there is no problem to insert new record, select and update action in the FormviewPage
2nd case - However, there is problem when i select a record in GV and direct to FormviewPage for edit this code is added in Formviewpage to open the record at readonly mode, no problem
Private Sub RF_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
If Session("RecordID") <> "" Then ' to check New or Old record
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
FormViewProject.ChangeMode(FormViewMode.ReadOnly)
End If
End Sub
however, no record if go further from readonly to edit mode then Code is added to the Edit button
Protected Sub BtnEdit_Click(ByVal sender As Object, ByVal e As EventArgs)
FormViewProject.ChangeMode(FormViewMode.Edit)
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
FormViewProject.DataBind()
End Sub
Now edit problem is solved but when go back to the 1st case (new record, and then edit) Now new record can be inserted, and then show it in readonly mode. but then try to go to edit mode, no record show i think BtnEdit_Click code is conflicted with the built-in "Edit" command Could anyone show me some info how formview retrieve specific record in a proper way?
I have a FormView bound to an ObjectDataSource that is bound to a business logic object. The business logic object has a Readonly field called "Id". When I try to update the formview, I get the following error message: The 'Id' property on the type specified by the DataObjectTypeName property in ObjectDataSource 'ObjectDataSourceNewsArticle' is readonly and its value cannot be set. How do I get the ObjectDataSource or the FormView to recognise that the id field is readonly, and to not try to update it?
View 3 RepliesI'm using a formview in Insert mode with an AccessDataSource. I want to switch to readonly mode upon insertion to let the user confirm the input worked, then give them the option to insert a new record. If I set the DefaultMode to Insert, then after the first record is inserted, I get a new blank insertion form (no confirmation). If I set the DefaultMode to ReadOnly, after insertion, I get a blank form (presumably because I am not on the record just inserted).
How do I get the just inserted record to display? If I need to set the ID of the formview to the just inserted record OnInserted, how do I get that given I'm using an AccessDataSource?

View 1 RepliesI have a GridView with two CheckBoxField columns. They both have ReadOnly property set to false, but html code generated for them has attribute disabled="disabled". So the value cannot be changed.
Generated HTML example:
<span disabled="disabled"><input id="ctl00_ContentBody_GridView_ctl02_ctl01" type="checkbox" name="ctl00$ContentBody$GridView$ctl02$ctl01" checked="checked" disabled="disabled" /></span>
how to figure it out?
One of the few fields that have their ReadOnly property equal to True then Edit and Update the value field is empty ReadOnly property is recorded.I also have a ReadOnly property and its value is not empty. (GridView to the SqlDataSource is connected)
