Listview not updating databsase with Dropdown list values - sql

Question

When I edit items in a Listview from a Dropdown list and press the standard update button the data is not updating.
This is the structure of my database.
CREATE TABLE [dbo].[Assets]
(
[AssetID] [INT] IDENTITY(20000,1) PRIMARY KEY NOT NULL,
[Asset] NVARCHAR(20) NOT NULL,
[Symbol] NVARCHAR(20) NULL,
[AssetType] NVARCHAR(20) CONSTRAINT chk_asttype CHECK (assettype IN ('Currencies',
'Indices',
'Stocks',
'Commodities')) NOT NULL,CREATE TABLE[dbo].[times]
(
timeid [INT] IDENTITY(20010,1) PRIMARY KEY NOT NULL,
timevalues NVARCHAR (15) DEFAULT '15 Minutes' NOT NULL
)CREATE TABLE [dbo].[results]
(
[resultid] [INT] IDENTITY(20016,1) PRIMARY KEY NOT NULL,
[result] [NVARCHAR](10)CONSTRAINT chk_result CHECK (result IN ('Won',
'Lost',
'Draw',
'Prepare',
'New Signal'))
)CREATE TABLE [dbo].[binarysignals]
(
[signalid] [INT] IDENTITY(30000,1) PRIMARY KEY NOT NULL,
[assetid] [INT]CONSTRAINT fk_binastid FOREIGN KEY REFERENCES assets(assetid) NOT NULL,
[signaldate][DATE] DEFAULT Getdate() NOT NULL,
[direction][VARCHAR](4) CONSTRAINT chk_bindirection CHECK (direction IN ('Call',
'Put')) DEFAULT NULL,
[strikeprice] [SMALLMONEY] DEFAULT NULL,
[expiryprice] [SMALLMONEY] DEFAULT NULL,
[starttime][SMALLDATETIME] DEFAULT NULL,
[expirytime][NVARCHAR](20) DEFAULT NULL,
[resultid] [INT]CONSTRAINT fk_binresid FOREIGN KEY REFERENCES results(resultid) DEFAULT 20016 NOT NULL,
[lastupdatedtime][SMALLDATETIME] DEFAULT Getdate() NOT NULL,
)
And here is my ASP.Net markup code

document.getElementById("lblTime").innerHTML = dt.toLocaleTimeString();
window.setTimeout("ShowTime()", 1000);
}

I try to update the Results value which is a Foreign key stored in the Binary Signals table coming from the Results table. Result field is used as the display text and the ResultId as the value for the dropdown list

Answer 1

Solved. The below was missing from the EditItemTemplate
<asp:Label ID="SignalIDLabel" runat="server" Text='<%# Bind("SignalID")%>'/>
