updating column rows in GridView C#

updating column rows in GridView C# - c#

I have a problem that I couldn't find a solution for.
As seen in the picture below, i have a gridView to display list of events. what i want is to compare "eventEndDate" column values with the current day, in order to update the last column rows, "eventStatus".
So, I added a while loop to read through the database and get the values of "EventEndDate" as the following:
while (reader.Read())
{
result.Add(reader.GetValue(4).ToString());
}
reader.Close();
Then, within the load method also I added these codes:
string currentDate = DateTime.Now.ToString("MMMM/d/yyyy");
//endDate = DateTime.Now.ToString("MMMM/d/yyyy");
//TextBox1.Text = Session["CountryName"].ToString();
country = Session["CountryName"].ToString();
SqlDataSource1.SelectCommand = "SELECT * FROM EventsEnglish WHERE CountryName ='" + country + "'";
SqlDataSource1.DataBind();
foreach (var lastDay in result)
{
string lastDayDate = Convert.ToDateTime(lastDay).ToString("MMMM/d/yyyy");
if (DateTime.ParseExact(lastDayDate, "MMMM/d/yyyy", CultureInfo.InvariantCulture) > DateTime.ParseExact(currentDate, "MMMM/d/yyyy", CultureInfo.InvariantCulture))
{
SqlDataSource1.UpdateCommand = "UPDATE EventsEnglish SET EventStatus = Open";
SqlDataSource1.DataBind();
}
else
{
SqlDataSource1.UpdateCommand = "UPDATE EventsEnglish SET EventStatus = Close";
SqlDataSource1.DataBind();
}
the problem is, I don't get any error messages but the event status doesn't update ...
So, what is i'm doing wrong???

please use ExecuteNonQuery() to update your table.

I am doing the same thing for a project. I use this type of c# grid connecting to sql server and the updates works fine, (you only have to change the boundfield values, the sql command for the update and the parameters for the update.

Dropdownlist in gridview edit template doesnt' update value of column

So I have a gridview that is bounded with a sql data source. After that I changed a edit template for one column and instead of textBox I used a dropdownlist. In that dropdownlist I entered two items and their values. Now when I update a gridview column where I installed dropdownlist doesn't update it old value to its new value but gets a NULL value.
This is my code:

Is there any other stuff I need to change so this could work ?

You need to Bind your DropDownList to your database field
<asp:DropDownList ID="ddlStatus" runat="server"
SelectedValue='<%# Bind("StatusP") %>'>
<asp:ListItem Value="">None</asp:ListItem>
<asp:ListItem Value="Prihvaćena">Prihvaćena</asp:ListItem>
<asp:ListItem Value="Odbijena">Odbijena</asp:ListItem>
</asp:DropDownList>
The key part is
SelectedValue='<%# Bind("StatusP") %>'
This will cause the value you select to pass to your datasource.

edit in detailsview with dropdownlist

I am fairly new at ASP.NET c#. I would like to edit a detailsview with a dropdown list. I have followed the instructions on this link -- This link-- and it was exactly what I orrigionally thought of. This is flawed however, because although I can see the items on my dropdown list, it does not actually update the database. I am at a loss. I have been trying to find an answer for a couple of days now and am unsure of what I need to do. Is there something I need to do in the backend? I will attach my code at the end as well. Currently I have nothing going on in the backend.

what am i doing wrong?

I would suggest adding an OnUpdating event handler so you can look at the CommandText before the query is executed. That should help you identify if there's an issue with the query.
In the markup:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" OnUpdating="SqlDataSource1_Updating" ... >
In the code-behind:
protected void SqlDataSource1_Updating(object sender, SqlDataSourceCommandEventArgs e)
{
string updateQuery = e.Command.CommandText;
//inspect the update query
}

Display data from another table in C#, Visual Studio 2010 (data binding?)

I have the following problem: I have 2 tables:
1) table1: STRANKA (ID_STRANKE(primary key), IME, PRIIMEK, TELEFON, NASLOV, POSTA)
2) table2: VOZILO (REG_STEVILKA(primary key), ID_STRANKE, ZNAMKA, MODEL, LETO_IZDELAVE, PROSTORNINA_MOTORJA, MOC_MOTORJA, TIP_MOTORJA, VIN_STEVILKA)
Each member of "STRANKA" can have 0:n members of "VOZILO", while each member of "VOZILO" has exactly 1 member from "STRANKA".
Now, I have DetailsView (DetailsView2 is actual name in code) which displays all columns from a certain member of "VOZILO". Now - what I want to do is to replace the column "ID_STRANKE" with "IME + PRIIMEK". To do this I must somehow connect these two tables or something ... I really don't know how to do it. Can somebody help? Thanks!

You need to join your 2 data tables. I've combined the two columns from STRANKE as one column and added STRANKE_ID as a data key, you could return them separately and use a template field :
<asp:DetailsView ID="DetailsView2" runat="server" AutoGenerateRows="False"
CellPadding="4" DataKeyNames="REG_STEVILKA,ID_STRANKE" DataSourceID="SqlDataSource4"
