QuestionInsert/Update/Delete Records in Dynamic Generated Textbox/Checkbox and Loop Through All Records Pin
guodl3-Jan-13 10:11
guodl3-Jan-13 10:11 
Hi,

Please enlight me how to insert/update/delete records based on generated textbox/checkbox.

I used the following code to generate the textbox/checkbox:

ASP.NET
<asp:Repeater ID="myRepeater" runat="server" >
 <HeaderTemplate>
     <table >
        <thead><tr>
          <th>Terminal Tab</th>
          <th>Terminal Attributes</th>
          <th>Values
        </th></tr></thead>
        <tbody>
 </HeaderTemplate>
        
 <ItemTemplate>
          <tr>
    	      <td><%# Eval("TabName") %></td>
	      <td><%# Eval("TagName") %></td>
              <td><%# GenerateTag(Eval("Datatype"))%></td>
          </tr>
 </ItemTemplate>
 <FooterTemplate>
            </tbody>
            </table>
 </FooterTemplate>
</asp:Repeater>


Below is the function of GenerateTag:

C#
/// <summary>
/// Generate tages based on data type.
/// </summary>
/// <param name="objDataType"></param>

protected string GenerateTag(object objDataType)
{
    String strTags = "";

    switch (objDataType.ToString()) {
        case "Char":
            strTags = "<input id=tagText type=text  />";
            break;
        case "Int":
            strTags = "<input id=tagInt type=text  />";
            break;
        case "Boolean":
            strTags = "<input id=cbx type=checkbox  />";
            break;
        default:
            strTags = "<input id=strInput type=text />";
            break;
    }
    return strTags;
}


I use the following SQL statement in myRepeater:

C#
           string strSQL = @"
        Select       T.ID
                              , T.TabID  TabID
                              , Tab.Name TabName
                              , T.TagName
                              , T.AppID
                              , T.DataType
                              , T.MinLen
                              , T.MaxLen
                              , A.Name AppName
                              , T.Description
         From TerminalAttrTag T 
              Left Join TerminalAttrApp A   on T.AppID = A.ID 
              Left Join TerminalAttrTab Tab on T.TabID = Tab.ID     
                 Where T.AppID = {0} or T.AppID = 1 
                               Order by T.TabID, T.SeqNo
                   ";
 
strSQL = String.Format(strSQL, AppID);
 
myRepeater.DataSource = bl.GetDataSet(ConnectionString, strSQL);
myRepeater.DataBind();


In screen, it shows:

Terminal Tab    Attributes    Values

Host Config     Host Name     (Textbox)
Host Config     Host IP       (Textbox)
Host Config     Timeout       (Textbox)


I can input below info:

Terminal Tab    Attributes    Values

Host Config     Host Name     Host Main
Host Config     Host IP       172.1.1.1
Host Config     Timeout       30


Now I want to be able to click "Add" button to input below record (2nd records). 

Terminal Tab    Attributes    Values

Host Config     Host Name     Host Backup
Host Config     Host IP       172.2.2.2
Host Config     Timeout       50


I am thinking to use DetailsView but in the end I give up due to the dynamic generated textbox.

1. Please enlight me how I can add code in 'Add' button to insert records. Or which part of code need to be fixed or rewrite? And please advise the suitable way to handle this.

2. After problem of add/delete/update records solved, please enlight me how to loop through the records. I need to save all records to database or xml files.

Thank you for your patient.
