Question

Hello developers I am using VS 2010 .I have a dev express grid in which I have a checkbox column.The problem is When i check the checkbox it gets checked but when i move to any other cell or column the checkbox gets automatically unchecked.Till now my code is as follows

 if (e.Column.ToString()=="Active" )
            {

                RepositoryItemCheckEdit edit = UserInfoGridView.GridControl.RepositoryItems.Add("CheckEdit") as RepositoryItemCheckEdit;


                column = e.Column;
                column.OptionsColumn.AllowSort = DevExpress.Utils.DefaultBoolean.False;
                column.Visible = true;
                column.VisibleIndex = 3;
                column.FieldName = "CheckMarkSelection";
                column.Caption = "Active";
                column.OptionsColumn.ShowCaption = true;
                column.OptionsColumn.AllowEdit = true;
                column.OptionsColumn.AllowSize = false;


                column.UnboundType = DevExpress.Data.UnboundColumnType.Boolean;

                column.ColumnEdit = edit;

            }

Well I found the Answer………What I did was this

   public frmLoad()
    {


        InitializeComponent();


        string DisplayQuery = "Select * from TableName";
         MasterDs = SqlHelper.ExecuteDataset(CommonClass.ConnectionString, CommandType.Text, DisplayQuery);
        MasterDs.Tables[0].Columns.Add("FLAG", typeof(string));

        MainGrid.DataSource = MasterDs.Tables[0];
        gridview.PopulateColumns();

        gridview.Columns["ID"].VisibleIndex = -1;
        gridview.Columns["FLAG"].VisibleIndex = -1;

        DevExpress.XtraEditors.Repository.RepositoryItemCheckEdit selectnew = new DevExpress.XtraEditors.Repository.RepositoryItemCheckEdit();
        gridview.Columns["ColName"].ColumnEdit = selectnew;
        selectnew.NullText = "";
        selectnew.ValueChecked = "Y";
        selectnew.ValueUnchecked = "N";
        selectnew.ValueGrayed = "-";

    }
