I'm losing the characteristics of my datagrid evrytime i do a refresh

[g_r_a_robinson]

I am using the ItemDataBound event to format some of the colours in my datagrid depending on the contents of the row, it works great. Problem is if i do a refresh i lose all the changes made by ItemDataBound which I don't want happening. Unless something new has been added to the grid I really don't want to have to re-bind my grid everytime a refresh occurs. For the most part I don't tend to add things to my grid. Is there some way of ensuring that my ItemDataBound changes can remain, maybe in viewstate or something?

Are you binding the grid on each postback?

 

ensure that your page load event has this in it...

 

If not IsPostBack then
    'bind grid here
end if

[g_r_a_robinson]

My problem is not a result of binding again i'm just losing the characteristics of ondatabind when i do a refresh

Post your code

Heres my page_load

private void Page_Load(object sender, System.EventArgs e)
	{

		String prefix = PathPrefix;
				
		NoteHeader_PNL.BackImageUrl = prefix + "/images/completeNoteHeader.gif";

		Background.Attributes.Add("BackGround", prefix + "/images/background.gif");
		//RowHeaderBar.Attributes.Add("RowHeaderBar", prefix + "/images/barForNotes.gif");
					
		String defaultMode = JobAdder.DefaultNoteAdd;

		if (defaultMode == "normalNoteAdd")
		{
			JobAdderForTheNoteScreen_PNL.Style.Add( "display", "none" );
		}
		
		if (defaultMode == "editForDefault")
		{
			JobAdderForTheNoteScreen_PNL.Style.Add( "display", "none" );
			//JobAdderForTheNoteScreen_PNL.Visible = false;
			NoteHeader_PNL.Visible = true;
			JobAdder.DefaultNoteAdd = null;
		}

		if (JobAdder.Calendar_Checked_Status == true)
		{
			NoteList_LST.Visible = false;
			Calendar_On_Notescreen_PNL.Visible = true;
		}
		
		if (JobAdder.Calendar_Checked_Status == false)
		{
			NoteList_LST.Visible = true;
			Calendar_On_Notescreen_PNL.Visible = false;
		}


		if (IsPostBack)
		{
		}

		else		
		{				
			//Its a regular select existing job
			roleid = links.RoleID;
	
			if (roleid == 1)
			{
				viewMode = JobViewerForAdmin.JobViewMode;
								
				if (viewMode == "view")
				{
					DisplayNotes();
					JobViewerForAdmin.JobViewMode = "";
				}
					
			}
			else
			{
				viewMode = JobWithNoteViewer.JobViewMode;
								
				if (viewMode == "view")
				{
					DisplayNotes();
					JobWithNoteViewer.JobViewMode = "";
				}

			}
		}				

		// First time around, lets populate the list boxes.
		if (!IsPostBack)
		{
			PopulateActionsDropDown();  
		}

			// Otherwise its a basic job add
		else
		{
					
		}


	}







Heres my bind function

private void BindNotes()
	{
		roleid = links.RoleID;
		
		if (roleid == 1)
		{
			userID = links.UserID;//JobViewerForAdmin.UsrID;

			jobID = (int)Session["JobID_By_Session"];
			//jobID = JobViewerForAdmin.JobID;
			if (jobID == 0)    // I put these in here for the add new job section
			{					// that needs to return an update view
				//jobID = (int)ViewState["jobID"];
				jobID = (int)Session["JobID_By_Session"];//JobSystem.JobIDforDefault;
				//JobViewerForAdmin.JobID = 0;//xyz

			}
		}
		else
		{
			userID = links.UserID;
			jobID = (int)Session["JobID_By_Session"];//JobWithNoteViewer.JobID;
			if (jobID == 0)
			{
				jobID = (int)Session["JobID_By_Session"];//JobSystem.JobIDforDefault;
				//JobWithNoteViewer.JobID = 0;//xyz
			}
		}
	
		noteSystem = new NoteSystem();
		noteData = noteSystem.GetNotesByUserAndJobID(userID,jobID);

	// Lets get the note id's and save them in our array for later
		DataTable noteTable = noteData.Tables[NotesData.NOTES_TABLE];

		if (NotesData.FlagUpdateNote != true)
		{
			noteIDList.Clear();
	

			foreach (DataRow noteID in noteTable.Rows)
			{
				int noteid = Int32.Parse(noteID[NotesData.NOTES_ID_FIELD].ToString());
		
				noteIDList.Add(noteid);
				IEnumerator E = arraylist.GetEnumerator();
				E.MoveNext();
			}
		}

		noteView = noteData.Tables[NotesData.NOTES_TABLE].DefaultView;

		NoteList_LST.DataSource = noteView;
		NoteList_LST.DataBind();
	}





heres my ItemDataBound event

private void NoteList_LST_ItemDataBound(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)

You're not calling BindNotes() from anywhere.

[g_r_a_robinson]

sorry i missed this, this is invoke from the page_load:

 

 

public void DisplayNotes()

{

if (JobAdder.DefaultNoteAdd == "normalNoteAdd")

{

JobAdderForTheNoteScreen_PNL.Style.Add( "display", "none" );

NoteHeader_PNL.Visible = true;

JobAdder.DefaultNoteAdd = null;

}

 

else

{

JobAdderForTheNoteScreen_PNL.Style.Add( "display", "block" );

NoteHeader_PNL.Visible = false;

//JobViewerForAdmin.JobID = 0;

}

 

 

BindNotes();

 

}
