Dynamically added Checked Changed Event is not Firing

[anish222]

hi seniors.. I have added columns and checkboxes Dynamically... But met with a problem that the CheckedChanged Event is not fired.. here is my Code..

protected void ddlRole_SelectedIndexChanged(object sender, EventArgs e)
{


        for (int i = 0; i < DtOperation.Rows.Count; i++)
        {
            Dt.Columns.Add(DtOperation.Rows[i][0].ToString());
        }
        dgrDynamic.DataSource = Dt;
        dgrDynamic.DataBind();   
.
.
        //addind check boxes dynamically.

        tcCheckCell = new TableCell();
        var checkBox = new CheckBox();

       // ActivityID|OperationID is stored to work it at the time of Save in CheckedChanged.

       checkBox.ID = DtOperation.Rows[i][0] + "|" + DtOperation.Rows[i][2];
       checkBox.AutoPostBack = true;
       checkBox.Checked = true;
       checkBox.CheckedChanged +=new EventHandler(checkBox_CheckedChanged);

        tcCheckCell.Controls.Add(checkBox);
                                        dgrDynamic.Rows[j].Cells.RemoveAt(GetColumnIndexByName((int)DtOperation.Rows[i][2]));
                    dgrDynamic.Rows[j].Cells.AddAt(GetColumnIndexByName((int)DtOperation.Rows[i][2]), tcCheckCell);
                    //(int)DtOperation.Rows[i][2]+2   
}


void checkBox_CheckedChanged(object sender, EventArgs e)
{

You need to re-load the dynamically created controls in your PageInit event or else the events for these controls will not be fired.

See how to use dynamic controls in asp.net for more information.
