I am having problem with the following code. Delete function does not work (throws scalar variable error). Update function does not work ... it does not throw any error, but it simply does not make changes to the database.
If I make exact DetailsView, everything works OK. Where is the problem?

Do you mean it doesn't work with a gridview but does work with a DetailsView? If so, then you need to set DataKeyNames for the gridview.
You can look at this for further details: http://fabdata.wordpress.com/2007/03/23/must-declare-the-scalar-variable-id/
I solved it by adding:
<asp:DetailsView ID="DetailsView1" runat="server" DataKeyNames="ID"....

I'm trying to create a GridView to display the contents of a table on my database. I want the user to be able to edit only one of the columns, so I set every other one to read only. When I test this, I can only edit the one column, like intended, but after updating, the other columns become null and post to the database. I don't know how to stop this from happening. Here is my code for the GridView. It is bound with one of Visual Studio's SQLDataSources.
I tried to create several events including RowEditing, RowUpdated, and RowUpdating, but with no luck. Nothing would stop the non-edited fields from getting replaced with NULL.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None" Align="center" Height="138px" Width="548px" BorderColor="#6600FF" BorderStyle="Ridge" HorizontalAlign="Center" DataKeyNames="Id" DataSourceID="SqlDataSource1" >

Edit: I found a working solution by changing the SQLDataSource's Update Query String to set the unchangeable categories to their original values and leaving the one changeable field to a parameter. I'll post the code for that here.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="*connection string here*" ProviderName="System.Data.SqlClient" SelectCommand="SELECT * FROM [Cart]" DeleteCommand="DELETE FROM [Cart] WHERE [Id] = #original_Id" InsertCommand="INSERT INTO [Cart] ([PhoneName], [Amount], [Price], [TotalPrice]) VALUES (#PhoneName, #Amount, #Price, #TotalPrice)" OldValuesParameterFormatString="original_{0}" UpdateCommand="UPDATE [Cart] SET [PhoneName] = PhoneName, [Amount] = #Amount, [Price] = Price, [TotalPrice] = TotalPrice WHERE [Id] = #original_Id" DataSourceMode="DataReader">
<DeleteParameters>
<asp:Parameter Name="original_Id" Type="Int32" />
</DeleteParameters>
<InsertParameters>
<asp:Parameter Name="PhoneName" Type="String" />
<asp:Parameter Name="Amount" Type="Int32" />
<asp:Parameter Name="Price" Type="String" />
<asp:Parameter Name="TotalPrice" Type="String" />
</InsertParameters>
<UpdateParameters>
<asp:Parameter Name="PhoneName" Type="String" />
<asp:Parameter Name="Amount" Type="Int32" />
<asp:Parameter Name="Price" Type="String" />
<asp:Parameter Name="TotalPrice" Type="String" />
<asp:Parameter Name="original_Id" Type="Int32" />
</UpdateParameters>
</asp:SqlDataSource>

The problem occurs when SelectCommand output inside SqlDataSource using field names with whitespaces (marked with SELECT * ... which selects all columns without using alias), while BoundField inside GridView control doesn't accept field/column names using whitespaces.
Therefore, you need to use SELECT statement in SelectCommand mentioning all field names used for DataField attribute in GridView, and only alias all columns that have whitespaces on them like this:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ...
SelectCommand="SELECT [RegID], [First Name] AS First_Name, [Last Name] AS Last_Name, [Email ID] AS Email_ID, [Password], [Confirm Password] AS Confirm_Password, DOB, Gender FROM [Registration] WHERE ([Email ID] = #Email_ID)"
...>
...
</asp:SqlDataSource>
Then in your GridView, declare all DataField field names with underscores or just remove whitespaces following convention in SelectCommand inside SqlDataSource, and use them with SortExpression attribute:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="4" DataKeyNames="RegID" DataSourceID="SqlDataSource1" ForeColor="Black" GridLines="Horizontal">
<Columns>
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
<asp:BoundField DataField="RegID" HeaderText="RegID" InsertVisible="False" ReadOnly="True" SortExpression="RegID" />
<asp:BoundField DataField="First_Name" HeaderText="First Name" SortExpression="First_Name" />
<asp:BoundField DataField="Last_Name" HeaderText="Last Name" SortExpression="Last_Name" />
<asp:BoundField DataField="Email_ID" HeaderText="Email ID" SortExpression="Email_ID" />
<asp:BoundField DataField="Password" HeaderText="Password" SortExpression="Password" />
<asp:BoundField DataField="Confirm_Password" HeaderText="Confirm Password" SortExpression="Confirm_Password" />
<asp:BoundField DataField="DOB" HeaderText="DOB" SortExpression="DOB" />
<asp:BoundField DataField="Gender" HeaderText="Gender" SortExpression="Gender" />
</Columns>
...
</asp:GridView>
With these setup above, the binding on BoundField should be working properly without changing field names inside DB.
NB: ... marks removed sections on code sample for brevity.

*I belive that the source of the error is in the bold lines
The Update function:
[DataObjectMethod(DataObjectMethodType.Update)]
public static int UpdateAnimal(Animal a, string newsAdress)
Animal a is the object paramter which the grid view get by using the select function,
but the adress is another paramter from session source which the function gets too.
However, since I added this paramter I have this new error.
Thanks.
You can do it like this:
Change your method with this one
public void UpdateAnimal(int animalId, string name, bool vertebrates, bool vegetarian, string newsAdress)
{
}
and your ObjectDataSource
<asp:ObjectDataSource ID="ObjectDataSourceAnimals" runat="server" DeleteMethod="DeleteAnimal" SelectMethod="GetAllAnimals" TypeName="BLProject.Animal" UpdateMethod="UpdateAnimal">
<DeleteParameters>
<asp:Parameter Name="a" Type="Object" />
<asp:SessionParameter Name="newsAdress" SessionField="Adress" Type="String" />
</DeleteParameters>
<SelectParameters>
<asp:ControlParameter ControlID="textSearch" Name="Search" PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="dropdownlistAnimalToSearch" Name="type" PropertyName="SelectedValue" Type="String" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="animalId" Type="Int32"/>
.......the other fields from Animal that you want to update
<asp:Parameter Name="name" Type="String"/>
<asp:Parameter Name="vegetarian" Type="Boolean"/>
<asp:Parameter Name="vertebrates" Type="Boolean"/>
<asp:SessionParameter DefaultValue="D:\\project\\Ilan Project 29-11\\Web\\NewsInfo" Name="newsAdress" SessionField="Adress" Type="String" />
</UpdateParameters>
</asp:ObjectDataSource>
Seems that when using DataObjectTypeName you cannot add parameters. The solution is to send some or all the properties of the Animal row edited as parameters plus the other parameter.
If you want to use OldValuesParameterFormatString="original_{0}", add this int original_animalid to the method input parameters.
I'm writing an web-app that keeps track of deadlines. With this app you have to be able to update records that are being saved in an SQL DB.
However I'm having some problem with my update in my aspx-file.

Thx in advance
You are using #ms_id in the where clause of your SQL Statement, but the line that sets that <asp:Parameter ... /> is commented out. Try uncommenting:
<%-- <asp:Parameter Name="ms_id" Type="String" /> --%>
and try again
This line;
<%-- <asp:Parameter Name="ms_id" Type="String" />--%>
appears to be commented out and is used in the SQL where clause.
I have a gridview where the data it shows depends on the textbox and button control. Since the gridview doesnt show anything (unless a user typed an input in the textbox) how can I fill it with all data from the tables? I'm thinking of inserting another gridview inside of the EmptyDataTemplate but is there any way I could show all the records even without user input?
Just started in ASP.NET so I really need your help guys.

I want to display all the records from a table if a user doesn't type any input (or fill the EmptyDataTemplate with records from the database).
Thanks again!
Execute the Select command of the returning data source as its gonna return the entire rows od the table and bind to the original grid in the (!IsPostBack) of the page_load and next time when you need to bind data based on text box input execute the query and bind the data to same grid.
