handling control array in runtime
-
i'm trying to implement control array in my app. the no of control will depend on user's requirement. total number will be gathered from database. therefore i had to make the code within a method.
private void CreatePictureBoxes() { .... .... PictureBox[] pcbMem = new PictureBox[intCount]; Label[] lblMem = new Label[intCount]; .... }since i'm doing the whole code in a method i can't access those controls outside of that method. it's also not possible for me to create them in class level as the total index is unkown to me initially. i don't know how to reasign the length of an array so it's being a problem for me. so please help me out to creating the controls so that i can use them from anywhere. -

Just declare them at class level and instanciate them inside the method.
PictureBox[] pcbMem;
Label[] lblMem;private void CreatePictureBoxes()
{
....
....
this.pcbMem = new PictureBox[intCount];
this.lblMem = new Label[intCount];
....
}

To solve this problem, you could use a generic list. using System.Collections.Generic; List pcbMem = new List(); Private void CreatePictureBoxes() { ... for (int i = 0; i < intCount; i++) { PictureBox myPcb = new PictureBox(); ... pcbMem.Add(myPcb); } }
