Why save them in the web config? only config settings should be there.

How about a separate xml file. You then have total control over the format of the xml and can read it using the XMLDocument object.

If you have knowledge, let others light their candles at it.

I am interested in the connectionstrings as there will be several conectionstrings in the web.config i.e. one for each database.
The database is selected on the start page and then the correct connectionstring should be used.
What do you think now?
Thanks

The difference with connection strings is threefold.

Firstly the nodes are distinguised by their name attribute

Secondly they are, or can be secured. Connection strings can be encrypted, stored in the registry and so on

Thirdly, they are easily maintainable in the IIS managment console.

Web,Config is the right place for them.

Yes, I do at present have the appsettings for other settings...
In this appsetting each line has a key which allows me to refer to it in code.
For example let's say today I add a setting for a business i.e. <lob>Accounts then next week there will be a new business, so then I will add another line to the setting i.e. <lob>Audits and so forth. So you see, these lines get added to every time.
Somehow I need to retrieve these values and populate a dropdownlist with i.e.Accoounts, Audits, etc...
The question is how do I refer to these settings if there is no key?
Thanks

Multiple Dynamic Control Postback Issue [modified]

Good morning,

I've searched the web for a week to find a solution to a problem, but I can't figure it out, so now I'll try to post directly what the problem is and hope that someone could explain me how to go ahead. I'm new to Asp.Net, and some years have passed since I used to programme in C/C++.

I have an aspx page with two "Controller" textboxes.
If you insert a number X in TB1, on the OnTextChanged event, a Placeholder is populated with X TextBoxes (the number you entered).
If you insert a number H in TB2, on the OnTextChanged event, a Placeholder2 is populated with H TextBoxes (the number you entered).

The problem is that each time you enter a number you have a postback, hence after the first time, you loose all the data and the TextBox Controls in the PlaceHolder already populated. I cannot use Ajax UPdatePanel, so I know I should save the user data with the viewstate or Session, but i don't have idea of how to recall them to repopulate the PlaceHolder after Postback.

Here is my code ~~C++~~C#(I tried to leave just the interesting parts).

<table>
    <tr><td valign="middle"></td>
             <td><asp:TextBox ID="cldtb" runat="server" OnTextChanged="cldtb_OnTextChanged" AutoPostBack="true"></asp:TextBox></td>
        <td valign="middle"><asp:Panel id="pnlEnterNumbers" runat="server">
           <asp:PlaceHolder id="myPlaceHolder" runat="server" /></asp:Panel> </td> </tr>

</table>

  protected void cldtb_OnTextChanged(object sender, System.EventArgs e)
  {
      int I, intNumberCount;

          // Get number of items to be entered.
          intNumberCount = System.Convert.ToInt16(cldtb.Text);

          if (intNumberCount > 0)
          {
              //Add one textbox to enter each item.
              System.Web.UI.WebControls.TextBox txtNumber;
              for (I = 1; I <= intNumberCount; I++)
              {
                  txtNumber = new System.Web.UI.WebControls.TextBox();
                  txtNumber.ID = "birthdate" + I;
                  txtNumber.MaxLength = 8;
                  myPlaceHolder.Controls.Add(txtNumber);

              }

              // Add number of items to viewstate
              ViewState["NumberCount"] = (I - 1);
              //Session["holdMe"] = myPlaceHolder;
          }
}

Still way to much, but it does show that you have no idea what you are doing.

Why are you creating the controls dynamically in the first place?

Thank you Mark.

Yes, I made a mistake in writing, I know it is C#.
I need dynamic controls because their number depends on the value of a static control.
I solved my problem with javascript.

I'm studying tutorials, and I'm learning step by step while practicing, also thanks to experts like you, that explain newbies how to proceed...

Using textbox with AJAX toolkit autocomplete control

Danpeking18-Feb-10 3:31

18-Feb-10 3:31

Hi, I have hooked up a textbox to an autocomplete extender control and it seems to work fine with me restricting what is displayed as the user types via a web method in the code behind. I am using the CreateAutoCompleteItem key value pairs method. I have also created an OnClientItemSelected event which can update the value of a hidden field.

The problem I have is when the user might want to retrieve a record and I want the textbox to display the correct value when the page loads. If possible making my textbox have key value pairs, etc.

Can anybody please suggest a way?
Thanks

this is code i wrote to check check boxes in datalist control
but if i checked all checkboxes only it is returning true not for one or multiple checkboxes
help me... Confused | :confused:

foreach (DataListItem dli in DataList1.Items)
        {
            CheckBox Chk = (CheckBox)dli.FindControl("CheckBox1");
            if (Chk.Checked)
            {
                str13 = "cheked";
            }
            else
            {
                str13 = "you need to check";
            }
        }

If you are talking about the value of LblErr.Text, it will always be according to the checked state of your last item in DataList1.
I am sure you can easily guess why is it so.

If you want your str13 to have "cheked" for one or multiple checkbox checked, just add a break statement just after the statement str13 = "cheked";

foreach (DataListItem dli in DataList1.Items)        
{
        CheckBox Chk = (CheckBox)dli.FindControl("CheckBox1");
        if (Chk.Checked)
        {
            str13 = "cheked";
            break;
        }
        else
        {
            str13 = "you need to check";
        }
}
LblErr.Visible = true;
LblErr.Text = str13;

This should solve your problem.

Your format should be dd/MM/yyyy HH:mm

It looks like you do not have Word (or the correct version of it) installed on your server.
