I have a MasterPage.master file and a BasePage class. The BasePage has a method called SetStatus where it uses the Master property's FindControl to get a reference to a TextBox and set the Text property. This method is called from child pages to update the status of some operation.

The problem I am having is that the text box is not being updated. It seems like the Text property keeps getting reset back to empty string somehow. I have stepped through the code and everything seems to be going well.

Any tips?

Thanks

Hi i am alkesh kashyap here the code which is working with myself properly If your problem solved from it then marked as

answer.

TextBox txtTemp = (TextBox)this.Master.FindControl("txtBoxID");
        //This line is use to check the text
        string text = txtTemp.Text;
        txtTemp.Text = "This is New Text";

Hi Friend,

The following code shows that , how to access master page controls and update them

void Page_Load ( ) {
   // gets a reference to a TextBox control inside a ContentPlaceHolder
   TextBox mpTextBox;
   ContentPlaceHolder mpContentPlaceHolder = 
      ( ContentPlaceHolder ) Master.FindControl ( "ContentPlaceHolder1" );
   if ( mpContentPlaceHolder != null ) {
      mpTextBox = ( TextBox ) mpContentPlaceHolder.FindControl ( "TextBox1" );
      if ( mpTextBox != null ) {
         mpTextBox.Text = "TextBox found!";
      }
   }
   // gets a reference to a Label control that not in a ContentPlaceHolder
   Label mpLabel = ( Label ) Master.FindControl ( "masterPageLabel" );
   if ( mpLabel != null ) {
      Label1.Text = "Master page label = " + mpLabel.Text;
   }
}

Kindly revert me is there any clarification.

Thanks for the responses. However, my problem is not how to update the text box which I have it coded just fine. The problem is the text goes back to empty.

Here is what I have so far:

protected void SetStatus(string message) {
  Label lblStatus = (Label)Master.FindControl("lblStatus");

  lblStatus.Visible = true;
  lblStatus.Text = message;
}

The above method is in my base page class and it's being called from child pages. The code executes but for some reason the text is not getting updated. I am not sure exactly why as I have seen sometimes the Page_Load is getting fired twice when I post back and maybe this is causing the problem. I tried tracing but it wasn't very helpfull. Is there any kind of tool that let's you see when a certain control is being updated and by who?

Thanks
 

alaa_tm:

1. protected void SetStatus(string message) {  
2.   Label lblStatus = ((Label)Master.FindControl("lblStatus"));  
3.   
4.   lblStatus.Visible = true;  
5.   lblStatus.Text = message;  
6. }  

protected void SetStatus(string message) {
  Label lblStatus = ((Label)Master.FindControl("lblStatus"));

  lblStatus.Visible = true;
  lblStatus.Text = message;
}

Hi Alaa

Try it Like this

((Label)(Page.Master.FindControl("lblstatus"))).Text = Message;

Hope this Help
