String to DataTable in using C#.Net

Title:How to bind data table using string array in using c#

We have already learnt data binding to data source controls.Now i would like to show how would we use the array list to bind the data to grid view etc.

Some  examples for JQuery Auto complete text boxhow to bind or Export CSV data to data table in below example describes the logic of iteration of array list to  data table.In the below i have used a string array to hold the string data and a grid view to display the resultant data of Data table.
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<asp:GridView ID="GvOrdr" runat="server"></asp:GridView>

DataTable dtOrdrName = new DataTable();
dtOrdrName.Columns.Add(new DataColumn("Name", typeof(string)));
string[] strSplitOp = new string[] { "bhaskar", "Siva", "Ram" };
for (int i = 0; i <= strSplitOp.Length - 1; i++)
DataRow NewDrow = dtOrdrName.NewRow();
NewDrow["Name"] = strSplitOp[i].ToString();
GvOrdr.DataSource = dtOrdrName;

UniqueId and ClientID in

Here i have given two scenarios to explain those importance in
In case of a control which is placed in a web form without Master Page:
The Id and Name attribute rendered to the browser are same as Id of control on server and thus the same Id/Name can be used

for programming a control in java script

In case of a control which is placed in a web form with Master Page:

The control Client side Id="<%=ServerofControl.ClientID%>" example:ct100_ContentPlaceHolderId_ServerIdofControl

The control Client side Name="<%=ServerofControl.UniqueID%>" example:ct100$ContentPlaceHolderId$ServerIdofControl

1.Add a text box and HTML button to webform/content page which has been page
<asp:TextBox runat="server" ID="txtwform"/>

<input type="button" value="cbutton" onclick="Show()"/>

2.Add the following to the web form (cphHead isId of ContentPaveHolder added to Head Section of Master Page)
<asp:Content ID="chead" ContentPlaceHolderID="cphead" runat="server">

function Show()
var test=document.<%=Page.Form.ame%>.<%=txtwform.UniqueID%>;

How to create object reference in Wpf

The creation of object reference in wpf will be easy when we compare with previous version of XAML.In previous versions we have to declare and binding Element name .In updated XAML we can used X:Reference to create object reference
<Label Target="{Binding ElementName=OId}">OrderId</Label>
<TextBox x:Name="Oid" />

 updated version:
<Label Target="{x:Reference Oid}">OrderId</Label>
<TextBox x:Name="Oid" />
<Label Target="{x:Reference Oname}">OrderName</Label>
<TextBox x:Name="Oname" />
<Label Target="{x:Reference Oslaes}">Sales</Label>
<TextBox x:Name="Osales" />
Note:The XAML X:Reference can supported in WPF frame work.In  XAML 2006 we have to use binding to reference the object

The ALTER TABLE statement conflicted with the FOREIGN KEY constraint

It Will happen when the primary key Field has null value which has been referenced to child table with foreign key relation.To avoid these kind of errors we need get the records which has null value in parent table.To get those details we need to use the below query .

select  * from Order O LEFT JOIN Sales s on O.Order_Id= s.Order_Id
WHERE s.Order_Id is null

If you are not get any data using this query ,we can solve in other using below queries

Second Method:
First i will get the records  which is not null  using foreign key filed.Then i will check the FK value with PK values .If any FK is referenced to null i will update record with existing PK value
select *from order where order_id is not null
update order  set order_id=4 where order_id=5
