Try using --
for(int i=1;i<=10;i++)
{
(TextBox) txt = (TextBox)FindControl(this.ClientID + "TextBox"+i);
}

OR

for(int i=1;i<=10;i++)
{
(TextBox) txt = (TextBox)FindControl(this.ClientID + "_TextBox"+i);
}

Hope this works for you.

The description which is shown in IntelliSense come from XML file. So, you should probably check whether this doc XML file exists or not.

Hi, i'm using asp.net 2.0 & c#. i have a functionality which i would be implementing in all my classes (e.g. language change [en-US], [zh-CN], etc.). i found a solution in the web that says i should inherit a base class. here's how my code would probably look like:

public partial class SiteHra_SiteHraHome : MyBaseClass{
}

public class MyBaseClass{
}

Here's my question.. Should MyBaseClass inherit System.Web.UI?

Thanks in advance!

If it's a webform, your base class should inherit from System.Web,UI.Page.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

how to show message box when data is in gridview on temporary basis.

Hi All
I developed my website in asp.net 2.0. i used master page. there are top menu and left menu in website.
left menu are related to particular top menu. when i click on any left menu page open there.
On the page there is some textboxes and other server controls. I insert some values in textboxes and click ADD TO Grid button. Then all values added temporarily to
the gridview below. like this user can add many rows in grid. after that he can save all rows in database on a single click of SAVE button. I used Datatable to bind gridview.
But if user added the rows in grid view and rather than pressing SAVE button he click on other top menu or left menu.
in this case there should be a message box when he click to another top or left menu. message like this - Do you want to save the records ?
if user click yes then control must be on the same page or data must be saved otherwise open the other menu.
Google (Gmail) also provide such type of facility, when you write some text to send but you do not send the message then there is also message box like
Do you want to Save this message as draft or Discard the message ?
I also want to do such type of activity.
Your answer is appreciated.

Hey Rajesh,

Don't just look only Google. We also have like that in our CP.

Have you never seen the text as below?? Smile | :)

Are you sure you want to naviate away from this page? 

You will lose any unsaved text. Is this OK? 

Press OK to continue, or Cancel to stay on the current page.

You can attach the javascript function in "onbeforeunload" event.

Hi All,

I have got some web pages which can be seen properly (with the style sheets applied to the page's contents) from the domain i am working on. But when others from a different domain or when accessed from anywhere else, the page seems to be missing its style sheet. Confused | :confused:

Can anyone please suggest some possible solutions so that i can try it out to tackle this? Sigh | :sigh:

the page from different domain is missing the CSS, right? Are you also working on that different domain? If you are not working on that then why you care? For example, you try to access the google homepage. The google homepage looks disorder. but what do you want to do about that? sooner or later, Google will fix their homepage..

How to access API functions in a C++ ActiveX Control from ASP.NET Page using either C# or VB

Member 253045010-Dec-07 10:22

10-Dec-07 10:22

I have spun my wheels already. I have also looked pretty much everywhere for my specific use case but I have not been able to find anything that helps me. Please help.

I have an ASP.NET page embedding an unmanaged C++ OCX within the page using the following code.

[code]

<%@ Page AspCompat="true" Language="C#" AutoEventWireup="true" CodeBehind="Anywhere.aspx.cs" Inherits="Anywhere_Example_CSharp.AnywhereExample" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>

<script runat="server" language="C#">
public void btn1_Click(object sender, EventArgs e)
{
mycontrol.AddUnconnected(10, 10, 0, 0);
}
</head>

<body>
<form id="form1" runat="server">
<asp:Button ID="Button1" runat="server" Text="Add Person" OnClick="btn1_Click" />
<OBJECT id="mycontrol" style="WIDTH: 773px; HEIGHT: 488px" classid=clsid:F3AA9E66-A723-11D2-A17D-0060975A5AFA>
<PARAM NAME="_Version" VALUE="65536">
<PARAM NAME="_ExtentX" VALUE="20452">
<PARAM NAME="_ExtentY" VALUE="12912">
<PARAM NAME="_StockProps" VALUE="0">
</OBJECT>
<asp:Label id="lblMessage" runat="server" />
<asp:PlaceHolder id="phMyPlaceHolder" runat="server" />
</form>
</body>
[/code]

The control get displayed properly. The trouble comes when I try to get access to the API functions in the OCX with ID "mycontrol". What I wanna do is call the method mycontrol.AddUnconnected(0, 0, 0, 0) on the OCX. Unfortunately this is not working.

In fact if I have function

[code]
public void btn1_Click(object sender, EventArgs e)
{
mycontrol.AddUnconnected(10, 10, 0, 0);
}
[/code]

not commented out as shown, the page is not displayed whereas if I comment out the line

[code]
mycontrol.AddUnconnected(10, 10, 0, 0);
[/code]

The page is displayed and the control works fine, except I cannot call the API functions.

How do I make the control that has been embedded inside a page using the <object> tag as shown above accessible to my server side controls / and server side scripts?

Your help is appreciated.

Thanks,

Melody

Somebody sure has embedded a C++ OCX in ASP.NET. SOS.

I have found a way to do by using javascript injection but that is not adequate. And even if that worked I still have a problem with passing values that are set using JavaScript back to the server.
Example code below

<br />
<br />
        protected void Page_Load(object sender, EventArgs e)<br />
        {                        <br />
            {<br />
<br />
                //register a script block (client side) for responding to Add Unconnected events<br />
                string ls_script = "<script language=\"JavaScript\">";<br />
                ls_script += "\n";<br />
                ls_script += "<!--";<br />
                ls_script += "\n";<br />
                ls_script += "function AddUnconnected() { ";<br />
                ls_script += "\n";                <br />
                ls_script += "\n";    <br />
            <br />
                //get handle to the progeny ocx already displayed on the screen. Use it to add individual<br />
                ls_script += "var ocx = document.getElementById(\"progeny\"); \n";                <br />
                ls_script += "if (ocx != null) { \n";<br />
                ls_script += "  var upn = ocx.AddUnconnected(0, 0, 0, 0); \n";<br />
                ls_script += "  var mom = ocx.AddPerson(upn, 2, 0); \n";                //mother<br />
                ls_script += "  var pap = ocx.AddPerson(upn, 1, 0); \n";                //father<br />
                ls_script += "  ocx.SmartDraw();\n";<br />
<br />
                //ls_script += " var xmlh = document.getElementById(\"MyXML\"); \n";<br />
                //ls_script += " if (xmlh != null) { \n";<br />
                //ls_script += "  xmlh.value = ocx.GetXMLString(); \n";<br />
                //ls_script += "   alert(xmlh.value); ";<br />
                //ls_script += "} \n";                <br />
<br />
                //Now set the value for the element XMLSTRING to the new xml string<br />
                ls_script += " var xml = document.getElementById(\"XMLSTRING\"); \n";<br />
                ls_script += " if (xml != null) xml.innerText = ocx.GetXMLString(); \n";<br />
                ls_script += "} \n";<br />
                ls_script += "alert(\"Nuclear Family Created\"); \n";              <br />
                ls_script += "}";<br />
                ls_script += "\n";<br />
                ls_script += "// -->";<br />
                ls_script += "\n";<br />
                ls_script += "</script>";<br />
                this.Page.RegisterClientScriptBlock("AddUnconnected", ls_script);<br />
<br />
                //add an event attribute to Button1 for responding to client side click events<br />
                this.Button1.Attributes.Add("onclick", "AddUnconnected()");                <br />

writing at server side??

Hi everyone, since I'm an ASP newbie, can you recommend a good article dealing with writing at the server side?? Take guest book postings as an example in which a page would write text from a text box down to a file in the server..

A quick tip about how to do it would be appreciated!
Thank you guys!

You can use standard C# code to write to flat files, but a guestbook is far more likely to write to a database.

Really??

And that would write at the server side not the client side?? Using the same read/write streams from IO??

I'll try it now, thanks Christian Smile | :)

Accessing property of inner class with <%# bind() %>

Federico Orlandini10-Dec-07 8:31

10-Dec-07 8:31

Hi all,

assuming that we have an FormView which is binded with an ObjectDataSource, which provide a List<myobject> list as SELECT result.
The list provided by the ObjectDataList is composed by some object of MyObject class, which is the following:

class MyObject
{
int a;
int b;
InnerObject oInner;
}

The InnerObject class is the following:

class InnerObject
{
int alpha;
string bravo;
}

I would like to bind the Text property on a asp:label object with the MyObject.oInner.bravo string, using the Eval().
Have you any idea about I can do it? Is it possible? Confused | :confused:

Thanks a lot
Regards
Federico

Yes, just bind to it as normal. Instead of binding to MyProperty, bind to oInner.bravo.

Hello Christian,

thanks for your reply. The Bind("oInner.bravo") works only with a Label in my FormView's ItemTemplate. If I try to use it in a DropDownList like the following:

<asp:dropdownlist id="ddlCategoriaCorsoEdit" runat="server" datasourceid="odsCategorie" datatextfield="Titolo" datavaluefield="ID" selectedvalue="<%# Bind("oInner.bravo") %>

I got a build error: "Unknow server tag" in the ASPX page

<uc1:visualizzacorso id="VisualizzaCorso1" runat="server" />

where VisualizzaCorso is my formview.
Have you any idea how it happens?? Smile | :)

Federico

Location of the web-services DLL

Hi,
I'm new to asp.net and using IIS in general.

I followed the steps at http://www.builderau.com.au/strategy/architecture/soa/Utilise-Web-services-in-the-real-world/0,339028264,339130846,00.htm[^]

- used wsdl.exe to generate a .cs file from the wsdl file.
- compiled the .cs file into a dll.

I installed IIS on my WinXP. I think it installed IIS 5.1. I tested sample asp.net vb and c# aspx code and it works fine.

My question is, where do I place the generated DLL? I have the sample.aspx that uses the DLL in the C:\Inetpub\wwwroot itself. I placed the DLL in this directory itself, but when I run the aspx, I get an error with the following line in aspx:
]]>
CS0246: The type or namespace name 'SampleNS' could not be found (are you missing a using directive or an assembly reference?)

It looks like it is not finding the DLL. Where am I supposed to place the DLL? I created a bin directory under C:\Inetpub\wwwroot and placed the dll there, but that didnt help either.

Can someone help?

Thank you so much.
