Hi Bhavtosh , I am able to make some headway into the problem , however i don't
suggest this to be an ideal solution as it is more a turnaround to get the things done
, what i have done is : Created a UserControl having a button say btnFirst and
another user control with btnSecond , now i have set a couple of public properties
that can serve my logic by setting some bool values which can be checked and necessary
logic can be executed , For E.g: My UserControl1 having btnFirst is as follows :
***************************************** First User Control
************************************************************
namespace UserControlTry
{
using System;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
public abstract class FirstButton : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.Button btnFirst;
protected bool hasClicked;
private void Page_Load(object sender, System.EventArgs e)
{
}
public void btnFirst_Click(object sender, System.EventArgs e)
{
hasClicked = true;
Session["boolVal"] = hasClicked;
}
public bool HasClicked
{
get
{
hasClicked = (bool)Session["boolVal"];
return hasClicked;
}
}
}
}
Now crazy thing out here is button click event is public because as u will see the
code in main webpage , it need to call this event from there , otherwise it leads to
another peculiar problem .
*************************************** Second User Control Code is As Follows
**************************************************************
namespace UserControlTry
{
using System;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
public abstract class SecondButton : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.Button btnSecond;
protected bool checkVisibility;
private void Page_Load(object sender, System.EventArgs e)
{
}
public bool setVisibility
{
get
{
return checkVisibility;
}
set
{
checkVisibility = value;
if(checkVisibility == true)
this.btnSecond.Visible = true;
else
this.btnSecond.Visible = false;
}
}
}
}
************************************************* Main Web Page That hosts both user
control ************************************************
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
namespace UserControlTry
{
public class WebForm1 : System.Web.UI.Page
{
protected FirstButton FirstButton1;
protected SecondButton SecondButton1;
private void Page_Load(object sender, System.EventArgs e)
{
if(!IsPostBack)
FirstButton1.Load += new System.EventHandler(FirstButton1.btnFirst_Click);
checkForButtonsVisibility();
}
public void checkForButtonsVisibility()
{
if(FirstButton1.HasClicked == true)
SecondButton1.setVisibility = false;
else
SecondButton1.setVisibility = true;
}
}
}
**************************************************************************************************************************************
Now the problem and the issue that i was facing was that series of event take place
like this :
1. Main Page Load event .
2. User Control's Load Event .
3. User Control's button's Click Event .
so in normal case it use to work but for second button to vanish first button has to
be clicked twice , because page load of web page use to take place before user control
, so what i did was made that event public and set it on load of user control , so it
started happening in first shot but had to compromise with security ,
i hope u can get it , i think sarvana's solution is also really good and neat way to
get things done ,
Please get back to me in case of any discrepancy ,
Regards ,
Mrinal
