Insert selected records (checkboxes) from asp gridView & perform CRUD operations

Scenario :- I have to perform CRUD operation for selected records ( check boxes) in a GridView  ID as described in the image.

No what we are doing  is to perform a for loop on datatgrid & get selected checkbox id in a string varibale separted by ','.After that we will create a DB function that will split the checkbox ID'd string in new row for each id.


It will make CRUD operation very easy


GridView in aspx:-

  <asp:DataGrid ID="grdList" DataKeyField="diagnosis_id" Runat="server" AutoGenerateColumns="False"
AllowPaging="False" PageSize="100" ShowHeader="true"  >
<Columns>
<asp:BoundColumn DataField="diagnosis_name" HeaderText="DIAGNOSIS" SortExpression="diagnosis_name asc">
<HeaderStyle Width="75%" HorizontalAlign="Center" ></HeaderStyle>
<ItemStyle CssClass="greylabelsmall"></ItemStyle>
</asp:BoundColumn>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid>

VB function to get selected checkboxes in datagrid

 Private Sub GetCheckedBox()
        For Each item As DataGridItem In grdICDList.Items
            If CType(item.FindControl("chkICD"), CheckBox).Checked Then
                icdIds = icdIds + Convert.ToString( grdList .DataKeys.Item(item.ItemIndex)) + ","
            End If
        Next
        If icdIds.Length > 0 Then
            If icdIds.LastIndexOf(",") > 0 Then
                icdIds = icdIds.Substring(0, icdIds.Length - 1)
            End If
            'SaveICDs()
            InsertDiagnosis(icdIds)
        End If
    End Sub

Now create a db Function like this:-


CREATE  FUNCTION [dbo].[Split]      
(      
 @RowData varchar(8000),      
 @SplitOn nvarchar(5)      
)       
RETURNS @RtnValue table      
(      
 Id int identity(1,1),      
 Data nvarchar(100)      
)      
AS       
BEGIN      
 Declare @Cnt int      
 Set @Cnt = 1      
      
 While (Charindex(@SplitOn,@RowData)>0)      
 Begin      
  Insert Into @RtnValue (data)      
  Select      
   Data = ltrim(rtrim(Substring(@RowData,1,Charindex(@SplitOn,@RowData)-1)))      
      
  Set @RowData = Substring(@RowData,Charindex(@SplitOn,@RowData)+1,len(@RowData))      
  Set @Cnt = @Cnt + 1      
 End      
       
 Insert Into @RtnValue (data)      
 Select Data = ltrim(rtrim(@RowData))      
      
 Return      
END 








And Use it in your stored procedures like this :-





                INSERT INTO INSERTABC         
                        (CPTID,   
                         
                         ICDID,   
                         CREATED_USER,         
                         CREATED_DATE,         
                         ISDELETED)         
       SELECT @CPTID,LTRIM(RTRIM(DATA)), @CREATED_USER,  GETDATE(),0   FROM SPLIT(@ICDIDS,','






Example :--


  SELECT DATA  FROM SPLIT(@ICDIDS, ',' )
Data will give you select check boxes ID in new rows.
