Please can you an example with a code sample

protected void Page_Load(object sender, EventArgs e)
{
// ** Player Calls**

if (!Page.IsPostBack)
{
if (!object.Equals(Session["UserId"], null))
{
string getPlayerCallsQuery = "SELECT P.PlayerCallId, P.ScID, G.Id FROM PalsCallList AS P, GameRegister AS G WHERE (G.Id='" + Session["UserId"].ToString() + "' and G.Id = P.ScID )";
dt = dbClass.ConnectDataBaseReturnDT(getPlayerCallsQuery);
if (dt.Rows.Count > 0)
{
PalsCallList.DataSource = dt;
PalsCallList.DataBind();
}
}
}



// **Get Player Games**
if (!Page.IsPostBack)
{
if (!object.Equals(Session["UserId"], null))
{
string getPlayerGames = "SELECT m.ScID, m.PlayerName, m.PlayerCallId, G.Id FROM mGame AS m, GameRegister AS G WHERE (G.Id='" + Session["UserId"].ToString() + "' and G.PlayerName = m.PlayerName )";
dt = dbClass.ConnectDataBaseReturnDT(getPlayerGames);
if (dt.Rows.Count > 0)
{
GridViewPlayerGames.DataSource = dt;
GridViewPlayerGames.DataBind();

}
}
}
}



// The click event
protected void PalsCallList_ItemCommand(object source, DataListCommandEventArgs e)
{
if (!IsPostBack)
{
if (!object.Equals(Session["UserId"], null))
{
if (e.CommandName == "Accept")
{
Label PlayerCallID = (Label)e.Item.FindControl("PlayerCallId1");
string PlayerCallID2 = PlayerCallID.Text;
string getPlayerCallId = "SELECT COUNT(*) FROM mGame WHERE (PlayercallId = '" + PlayerCallID2 + "')";
string getPlayerName = "SELECT PlayerName FROM GameRegister WHERE (Id = '" + Session["UserId"].ToString() + "')";
DataSet ds = new DataSet();
SqlCommand cmd = new SqlCommand();
object dPlayerCallId = dbClass.ExecuteDBScalar(getPlayerCallId);
object dPlayerName = dbClass.ExecuteDBScalar(getPlayerName);
int scalarValue1 = (Int32)dPlayerCallId;
string scalarValue2 = dPlayerName.ToString();
string PlayerName = scalarValue2;
string PlayerCallId = PlayerCallID2;
string ScID = Session["UserId"].ToString();

if (scalarValue1 < 4)
{


string CreateGame = "INSERT INTO [mGame] (ScID,PlayerName,PlayerCallId) VALUES('" + Session["UserId"].ToString() + "','" + PlayerName + "','" + PlayerCallId + "')";
dbClass.ConnectDataBaseToInsert(CreateGame);
string DeletePal = "DELETE (*) From PalsCallList where (ScId ='" + Session["UserId"].ToString() + "'AND PlayerCallId ='" + PlayerCallId + "')";
dbClass.ConnectDataBaseToDelete(DeletePal);

Response.Redirect("~/GamePage.aspx?Id=" + Session["UserId"].ToString());
}
}
}
}
}

Hi, Please help, I posted a question, but it was voted to be closed. I have tried all I could to resolve but to no avail. I improved my question as below.

I am working on a web application that has many pages including Master page. One page I call UserBestPage.aspx (not real name) has GridView control that has a custom template, in the template I have a PlaceHolder control with ID= phRow where I will like to put Button control dynamically at run time. So in UserBestPage.aspx.cs I also have a Class I called CreateUserButton that will create three buttons that I will user in the same code-behind page by calling their method.

My question is, how do I code my CreateUserButton Class, and how to call the method to where I want it to be.

This is the code I tried:

public class CreateUserButton
{
}
public void CreateUser1Button()
{
ContentPlaceHolder ContentPlaceHolder1 = Page.Master.FindControl("ContentPlaceHolder1") as ContentPlaceHolder;

PlaceHolder phRows = (PlaceHolder)ContentPlaceHolder1.FindControl("phRow");
Button b = new Button();
phRow.Controls.Add(b);
}

But how do I resolve the issue. I am still new in this. please help.

Hi, thanks for your help so far. I tried the code the former error message was gone, but new error message is: System.NullReferenceException: Object reference not set to an instance of an object.pointing to placeholder.Controls.Add(button);
