Dont think it is possible.
U need to use different validation controls for different text boxes.

I think you need to loop thru each textbox and assign the validator to it.

Or you could create validators for each textbox.

Surely this would simply update the "ControlToValidate" property multiple times and still end up verifying only a single textbox?

I have a java script

function goToNewPage(dropdownlist)
{ var url = dropdownlist.options(dropdownlist.selectedIndex).value;
if (url != "")
{ window.open(url); } }

I have a dropdownlist and in code behind file I have this code

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList1.Attributes.Add("onchange","goToNewPage(this.value)");

}

But it is not doing anything. Even if I set break points it doen't go there.

All I want that if I select ant item in dropdownlist it takes me to some url.

Try placing this in page load event and remove selected index changed event.

You can put a alert in your javascript and see whether you are getting any message or not.

I have a table with two columns
AppName AppLocation
TestApp1 folder1
TestApp2 folder2
TestApp3 folder3
TestApp4 folder4

I have to shows data of column AppName in dropdown list.
I created a sqldatasource and bound that to dropdownlist.
I set DataTextField = AppName and DataValueField = AppLocation.

Now I have a java script I called it at onchange method e.g which is always in or tags in html. But as I already bound the dropdownlist with datasource so in html source I couldn’t see or tags so where is onchange method where I can call java script.

Hello,

i am working on a project that requires users to goto a certain web page and this web page will display their system specs

i can do that using ASP.net / WMI, however that will give me the specs for the server, what i really need actaully is the specs for the client (ex. OS, Physical Memory, computerName, etc.)
is there a way to do that without doing ActiveX approach?

any ideas

thank you Smile | :)

It is showing me following items which are in database.

first index though I attach sqldatasource to dropdown.

--Select Item--
App1
App2
App3

Do something like this:

dropdownlist.Items.Add(new ListItem("--Select Item--"));
dropdownlist.AppendDataBoundItems = true;

dropdownlist.datasource = somedatasource;
dropdownlist.TextField = "Something";
dropdownlist.ValueField = "somefield";
dropdownlist.DataBind();

Thats all you have to do. Add an item in the list and then set AppendDataBoundItems = true before you bind the list to a data source.

Walk all controls on a page [modified]

I've created a literal for each of my text snippets (<asp:literal id="ABCDUnique">blah blah blah). I have other literals that are updated based on code execution, so that is the reason all literals start with ABCD.

In Page_Load, I do something like:

string pageName = "UniqueName";
languageCode = 1;  // Maps to English in database // Global to page
TranslateControls(pageName, this.Controls);

I then define the TranslateControls method as:

private void TranslateControls(string pageName, ControlCollection controls)
{
   for (int i=0; i < controls.Count; i++)
   {
      Control ctrl = controls[i];
      if (ctrl.HasControls())
      {
         // logger.Trace("Control: {0} has {1} child controls.", ctrl.UniqueID, ctrl.Controls.Count);
         TranslateControls(pageName, ctrl.Controls);
      }
      else
      {
         if (ctrl.GetType() == typeof(System.Web.UI.WebControls.Literal))
         {
            // check name
            if (ctrl.UniqueID.StartsWith("ABCD"))
            {
               // Replace with database lookup
               Literal litTemp = (Literal)ctrl;
               Database db = new Database();
               string textTranslation = db.GetText(pageName, ctrl.UniqueID, languageCode);
               litTemp.Text = textTranslation;
            }
         }
      }
   }
}

Problem is, some controls are ignored -- when logging/stepping through, it appears that they are not part of the ControlCollection. Any thoughts/ideas?

-- modification
When page is initially loaded, all controls are displayed properly. However, on postback, some controls are missed and appear blank (odd, as they have initial text, and the db.GetText method returns either valid text or ctrl.UniqueID surrounded by underscores).
-- end modification

Thanks,
Glenn

Even with the else removed, the literals do not appear.

Knowing this bit had something to do with it, after much head-banging/debugging, I realized that my literal was not listed in the .cs file.

My non-required fields displayed, as they are defined:

<label for="txtBillFirstName"><asp:label id="lblBillFirstName" runat="server"><asp:literal runat="server" id="litTextBillNameFirst">First Name:</asp:literal></asp:label></label><br />

but the [initially] required fields were not, defined as:

<label for="txtBillFirstName"><asp:label id="lblBillFirstName" runat="server">* <asp:literal runat="server" id="litTextBillNameFirst">First Name:</asp:literal></asp:label></label>

Apparently, you can have an asp:literal in an asp:label if it is the only thing in the label, but mixing text with a literal doesn't appear to work.

The initial text displayed on the page load, but not on a postback - not sure why even the * didn't show up. Some of the fields are only required based on selections made on the form, so if I cause the error conditions, those labels displayed as required, which threw me off track a little.
