Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

Remember i order to do that in U2 you must register the U1 and after that you can access your u1 method in U2 like this

u1.Mymethod();

Hope this Helps

Good Morning lakshmichawala

I will show you an Example of how you do it. i will create a Small Example.

First i will create a usercontrol and name i U1 like and it will have a method that will display a string like this

cs will look like this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class U1 : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    public String Message()
    {
        return "Message from U1 User control";
    }
}

and the html will be like this

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="U1.ascx.cs" Inherits="U1" %>
<asp:Label ID="lblU1" runat="server" Text="Usercontrol 1"></asp:Label>

and second thing is to create a Second user control and name it U2

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="U2.ascx.cs" Inherits="U2" %>
<%@ Register src="U1.ascx" tagname="U1" tagprefix="uc1" %>
<asp:Label ID="lblU2" runat="server" Text="User Control 2"></asp:Label>

<p>
    &nbsp;</p>
<p>
    &nbsp;</p>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

as you can see i have registered the U1 and in my U2 i can use the Function that i have made public like this in the button click

protected void Button1_Click(object sender, EventArgs e)
 {
     U1 obj = new U1();

     String Message;

     Message = obj.Message();

     Response.Write(Message);

 }

and a hardcoded message will come from the U1.

Hope this helps

Thanks

If you're trying to interact between two already loaded instances of different user controls I would possibly use an event. For example, when u2 button is clicked raise an event to the calling page, the calling page can then call the method in u2 as it already knows about it.

Alternatively, you can create a property on u2 of type u1 and the consuming page could set the property on u2 to the instance of u1 on the page, u2 will then have access to u1 and its methods.

What does it mean ? If you want to take database back up, from where ASP.NET came from. This is only about C#.

I have table like that:

wel here is Event

void grid_RowCreated(object sender, GridViewRowEventArgs e) {
if (e.Row.DataItem == null) {
return;
}
LinkButton cmdCity = (LinkButton)e.Row.FindControl("cmdCity");
if (cmdCity != null) {
int id = (int)grid.DataKeys[e.Row.RowIndex].Value;
cmdCity.CommandArgument = id.ToString();
}
}

and this event retrieves from data only one field concrete ID
I want to retriwe another ID's to like countryid, regionid or etc.

How do that??

The obvious way is to create a string datakey which is an amalgamation of ids. There's only one data key value, so it needs to contain the values you want, or give you what you need to look them up

I have not written whole code but
when This Event will rise, corresponding row from data binds to e.Row.DataItem
and this line

int id = (int)grid.DataKeys[e.Row.RowIndex].Value;

retrieves only one field from data and it's PK ID.
I want to retrieve aother values too.

there is grid.DataKeys[e.Row.RowIndex].Values too, but i didn't understand ho do it.

I have created a very powerful web-based software as part of my thesis. Though, nobody helped me in my project, yet I have to submit my software with full source code. Some of the features of my software are unique & even not available in SAS or SPSS. However, some of the scientists at my Instt. will publish & commercialize it without mentioning my name anywhere and all my effort will so far, would become futile.

Is there, any way that I can make the source code uneditable or encrypted, so that nobody can edit it except me. Or is there any way that I put my name in the source code such that nobody will be able to remove afterwards.

Please help Frown | :(
